Found 45 papers in cond-mat We analyze possible nodal superconducting phases that emerge from a doped
nodal-line semimetal. We show that nodal-line superconducting phases are
favored by interactions mediated by short-range ferromagnetic fluctuations or
Hund's coupling. It is found that the leading pairing channels are
momentum-independent, orbital-singlet and spin-triplet. In the pairing state,
we show that the Bogoliubov-de Gennes (BdG) Hamiltonian hosts a pair of
topologically protected nodal rings on the equators of the torus Fermi surface
(FS). Using a topological classification for gapless systems with inversion
symmetry, we find that these nodal rings are topologically nontrivial and
protected by integer-valued monopole charges $\nu = \pm 2$. In the scenario of
pairing driven by ferromagnetic fluctuations, we analyze the fate of
superconductivity in the magnetically ordered phase. Based on Ginzburg-Landau
free energy analysis, we find the energetically favored superconducting state
is characterized by the coexistence of two pairing orders whose $\bf d$-vectors
are perpendicular to the magnetization axis $\bf M$ with their phases unfixed.
In this case, each nodal loop in the pairing state splits into two, carrying a
$\pm 1$ monopole charge. For bulk-boundary correspondence, these nodal rings
enclose flat-band Majorana zero modes on top and bottom surface Brillouin Zones
with distinct $\mathbb{Z}$-valued topological invariants.
With neutron star applications in mind, we developed a theory of diffusion in
mixtures of superfluid, strongly interacting Fermi liquids. By employing the
Landau theory of Fermi liquids, we determined matrices that relate the currents
of different particle species, their momentum densities, and the partial
entropy currents to each other. Using these results, and applying the
quasiclassical kinetic equation for the Bogoliubov excitations, we derived
general expressions for the diffusion coefficients, which properly incorporate
all the Fermi liquid effects and depend on the momentum transfer rates between
different particle species. The developed framework can be used as a starting
point for systematic calculations of the diffusion coefficients (as well as
other kinetic coefficients) in superfluid Fermi mixtures, particularly, in
superfluid neutron stars.
We develop a model to describe the mixed valence regime in magic-angle
twisted bilayer graphene (MATBG) using the recently developed heavy-fermion
framework. By employing the large-$N$ slave-boson approach, we derive the
self-consistent mean field equations and solve them numerically. We find that
the SU(8) symmetry constraint moir\'e system exhibits novel mixed-valence
properties which are different from conventional heavy-fermions systems. We
find the solutions describing the physics at the filling near the Mott
insulator regime in the limit of strong Coulomb interactions between the
flat-band fermions. Our model can provide additional insight into the possible
microscopic origin of unconventional superconductivity in MATBG.
In this study, we conducted a numerical investigation on the Hall conductance
($\sigma_{Hall}$) of graphene based on the magnetic energy band structure
calculated using a nonperturbative magnetic-field-containing relativistic
tight-binding approximation (MFRTB) method. The nonperturbative MFRTB can
revisit two types of plateaus for the dependence of $\sigma_{Hall}$ on Fermi
energy. One set is characterized as wide plateaus (WPs). These WPs have filling
factors (FFs) of 2, 6, 10, 14, etc. and are known as the half-integer quantum
Hall effect. The width of WPs decreases with increasing FF, which exceeds the
decrease expected from the linear dispersion relation of graphene. The other
set is characterized by narrow plateaus (NPs), which have FFs of 0, 4, 8, 12,
etc. The NPs correspond to the energy gaps caused by the spin-Zeeman effect and
spin-orbit interaction. Furthermore, it was discovered that the degeneracy of
the magnetic energy bands calculated using the nonperturbative MFRTB method
leads to a quantized $\sigma_{Hall}$.
Single-atom catalysts are considered as a promising method for efficient
energy conversion, owing to their advantages of high atom utilization and low
catalyst cost. However, finding a stable two-dimensional structure and high
hydrogen evolution reaction (HER) performance is a current research hotspot.
Herein, based on the first-principles calculations, we identify the HER
properties of six catalysts (TM@MoSi2N4, TM = Sc, Ti, V, Fe, Co, and Ni)
comprising transition metal atoms anchored on MoSi2N4 monolayer. The results
show that the spin-polarized states appear around the Fermi level after
anchoring TM atoms. Therefore, the energy level of the first available
unoccupied state for accommodating hydrogen drops, regulating the bonding
strength of hydrogen. Thus, the single transition metal atom activates the
active site of the MoSi2N4 inert base plane, becoming a quite suitable site for
the HER. Based on {\Delta}GH*, the exchange current density and volcano diagram
of the corresponding catalytic system were also calculated. Among them,
V@MoSi2N4 ({\Delta}GH* = -0.07 eV) and Ni@MoSi2N4 ({\Delta}GH* = 0.06 eV)
systems show efficient the HER property. Our study confirms that the transition
metal atom anchoring is an effective means to improve the performance of
electrocatalysis, and TM@MoSi2N4 has practical application potential as a high
efficiency HER electrocatalyst.
Despite its apparent complexity, our world seems to be governed by simple
laws of physics. This volume provides a philosophical introduction to such
laws. I explain how they are connected to some of the central issues in
philosophy, such as ontology, possibility, explanation, induction,
counterfactuals, time, determinism, and fundamentality. I suggest that laws are
fundamental facts that govern the world by constraining its physical
possibilities. I examine three hallmarks of laws--simplicity, exactness, and
objectivity--and discuss whether and how they may be associated with laws of
physics.
Topological quantum materials (TQMs) have symmetry protected band structures
with useful electronic properties that have applications in information,
sensing, energy, and other technologies. In the past 10 years, the applications
of TQMs in the field of energy conversion and storage mainly including water
splitting, ethanol electro-oxidation, battery, supercapacitor, and relative
energy-efficient devices have attracted increasing attention. The novel quantum
states in TQMs provide a stable electron bath with high conductivity and
carrier mobility, long lifetime, and determined spin states, making TQMs an
ideal platform for understanding the surface reactions and looking for highly
efficient materials for energy conversion and storage. In this Perspective, we
present an overview of the recent progress regarding topological quantum
catalysis. We describe the open problems, and the potential applications of
TQMs in water splitting, batteries, supercapacitors, and other prospects in
energy conversion and storage.
Electrons in two-dimensional (2D) Dirac materials carry local band geometric
quantities, such as the Berry curvature and orbital magnetic moments, which,
combined with electron-phonon coupling, may affect the phonon dynamics in an
unusual way. Here, we propose intrinsic nonreciprocal linear and circular
phonon dichroism in magnetic 2D Dirac materials, which originate from nonlocal
band geometric quantities of electrons and reduce to pure Fermi-surface
properties for acoustic phonons. We find that to acquire the nonreciprocity,
the Fermi pocket anisotropy rather than the chirality of electrons is crucial.
Two possible mechanisms of Fermi pocket anisotropy are suggested: (i) trigonal
warping and out-of-plane magnetization or (ii) Rashba spin-orbit interaction
and in-plane magnetization. As a concrete example, we predict appreciable and
tunable nonreciprocal phonon dichroism in 2H-MoTe 2 on a EuO substrate. Our
finding points to a different route towards electrical control of phonon
nonreciprocity for acoustoelectronics applications based on 2D quantum
materials.
Light-matter interactions in solid-state systems have attracted considerable
interest in recent years. Here, we report on a room-temperature study on the
interaction of tungsten disulfide (WS$_2$) monolayer excitons with a hybrid
plasmon polariton (HPP) mode supported by nanogroove grating structures milled
into single-crystalline silver flakes. By engineering the depth of the
nanogroove grating, we can modify the HPP mode at the A-exciton energy from
propagating surface plasmon polariton-like (SPP-like) to localized surface
plasmon resonance-like (LSPR-like). Using reflection spectroscopy, we
demonstrate strong coupling between the A-exciton mode and the lower branch of
the HPP for a SPP-like configuration with a Rabi splitting of 68 meV. In
contrast, only weak coupling between the constituents is observed for LSPR-like
configurations. These findings demonstrate the importance to consider both the
plasmonic near-field enhancement and the plasmonic damping during the design of
the composite structure since a possible benefit from increasing the coupling
strength can be easily foiled by larger damping.
A topological insulator is a quantum material which possesses conducting
surfaces and an insulating bulk. Despite extensive researches on the properties
of Dirac surface states, the characteristics of bulk states have remained
largely unexplored. Here we report the observation of spinor-dominated
magnetoresistance anomalies in the topological insulator $\beta $-Ag$_2$Se,
induced by a magnetic-field-driven band topological phase transition. These
anomalies are caused by intrinsic orthogonality in the wave-function spinors of
the last Landau bands of the bulk states, in which backscattering is strictly
forbidden during a band topological phase transition. This new type of
longitudinal magnetoresistance, purely controlled by the wave-function spinors
of the last Landau bands, highlights a unique signature of electrical transport
around the band topological phase transition. With further reducing the quantum
limit and gap size in $\beta $-Ag$_2$Se, our results may also suggest possible
device applications based on this spinor-dominated mechanism and signify a rare
case where topology enters the realm of magnetoresistance control.
We studied the influence of a magnetic field (MF) on epitaxial growth and
magnetic properties of Fe(001) films deposited on MgO(001). Thanks to modular
sample holders and a specialized manipulator in our multi-chamber ultrahigh
vacuum system, the films could be deposited and annealed in an in-plane MF of
100 mT. In situ scanning tunnelling microscopy showed that MF had a strong
influence on the film morphology, and, in particular, on the structure of
surface steps. The magnetic properties were studied ex situ using magneto-optic
Kerr effect (MOKE) magnetometry and microscopy. We showed that the moderate
in-plane magnetic field applied during growth has the visible impact on the
magnetic properties. The observed angular dependence of the MOKE loops and
domain structures were discussed based on a magnetization reversal model. In
particular we found that magnetization reversal occurs via 90{\deg} domains and
the reversal differs for the no-field and in-field grown samples, in
correlation with the film morphology.
Solution-processed two-dimensional (2D) materials hold promise for their
scalable applications. However, the random, fragmented nature of the
solution-processed nanoflakes and the poor percolative conduction through their
discrete networks limit the performance of the enabled devices. To overcome the
problem, we report conduction modulation of the solution-processed 2D materials
via the Stark effect. Using liquid-phase exfoliated molybdenum disulfide (MoS2)
as an example, we demonstrate nonlinear conduction modulation with a switching
ratio of >105 by the local fields from the interfacial ferroelectric
P(VDF-TrFE). Through density-functional theory calculations and in situ Raman
scattering and photoluminescence spectroscopic analysis, we understand the
modulation arises from a charge redistribution in the solution-processed MoS2.
Beyond MoS2, we show the modulation may be viable for the other
solution-processed 2D materials and low-dimensional materials. The effective
modulation can open their electronic device applications.
We report the doping high concentration of tetravalent Ge4+ ions (5 mol % for
x = 0.05 to 30 mol % for x = 0.30) at the Fe3+ sites of Fe2-xGexO3 system by
chemical coprecipitation route. The charge state of Fe and Ge ions has been
modified into lower values, in addition to their normal +3 and +4 states, to
stabilize the rhombohedral phase of hematite ({\alpha}-Fe2O3) structure. X-ray
photoelectron spectra and optical band gap measurements indicated a combination
of ionic and covalence character of metal-oxygen bonds as an effect of Ge
doping in hematite structure. The Ge doped hematite samples have exhibited wide
band gap semiconductor properties with band gap 4.50-4.70 eV and remarkably
enhanced electrical conductivity ({\sigma} ~ 10-4 S/m) in comparison to
{\alpha}-Fe2O3 (10-11 S/m). The thermo-conductivity measurements using warming
and cooling modes showed a highly irreversible feature in the semiconductor
regime at higher temperatures. Some of the samples indicated metal-like state
at lower temperature, in addition to semiconductor state. Our experimental
results confirmed the strategy of enhancing electrical conductivity by doping
tetravalent ions in hematite structure. It has been understood that combination
of ionic and covalence character of the metal-oxygen bonds has played an
important role in modifying the semiconductor properties in Ge doped Fe2O3
system.
We study giant atoms coupled to a one-dimensional topological waveguide
reservoir. Under the Born-Markov approximation, we obtained practical coherence
and correlated dissipative interactions between giant atoms mediated by
topological waveguide reservoirs, which depend on the topological phase in the
topological waveguide. In the bandgap regime, only coherent interactions exist
and decay exponentially with distance, corresponding to photon-bound states'
appearance and the photon distribution's exponential decay. Then, we discuss
the appearance of photon-bound states when the frequencies of the giant atoms
lie in different band gaps. A chiral photon distribution occurs when the giant
atoms coupled to two sub-lattice points differ in intensity and resonate with
the waveguide, which stems from the fact that the photon-bound state can be
considered as a topological edge state, which is insensitive to off-diagonal
disorder. Finally, we find that for the same bandgap width, the excitation
transfer rate is faster in topological phases than in trivial phases. Our work
will promote the study of topological matter coupled to giant atoms.
Topological phase transitions go beyond Ginzburg and Landau's paradigm of
spontaneous symmetry breaking and occur without an associated local order
parameter. Instead, such transitions can be characterized by the emergence of
non-local order parameters, which require measurements on extensively many
particles simultaneously - an impossible venture in real materials. On the
other hand, quantum simulators have demonstrated such measurements, making them
prime candidates for an experimental confirmation of non-local topological
order. Here, building upon the recent advances in preparing few-particle
fractional Chern insulators using ultracold atoms and photons, we propose a
realistic scheme for detecting the hidden off-diagonal long-range order
(HODLRO) characterizing Laughlin states. Furthermore, we demonstrate the
existence of this hidden order in fractional Chern insulators, specifically for
the $\nu=\frac{1}{2}$-Laughlin state in the isotropic Hofstadter-Bose-Hubbard
model. This is achieved by large-scale numerical density matrix renormalization
group (DMRG) simulations based on matrix product states, for which we formulate
an efficient sampling procedure providing direct access to HODLRO in close
analogy to the proposed experimental scheme. We confirm the characteristic
power-law scaling of HODLRO, with an exponent $\frac{1}{\nu} = 2$, and show
that its detection requires only a few thousand snapshots. This makes our
scheme realistically achievable with current technology and paves the way for
further analysis of non-local topological orders, e.g. in topological states
with non-Abelian anyonic excitations.
Ultraviolet-ozone (UV-O3) treatment is a simple but effective technique for
surface cleaning, surface sterilization, doping and oxidation, and is
applicable to a wide range of materials. In this study, we investigated how
UV-O3 treatment affects the optical and electrical properties of molybdenum
disulfide (MoS2), with and without the presence of a dielectric substrate. We
performed detailed photoluminescence (PL) measurements on 1-7 layers of MoS2
with up to 8 minutes of UV-O3 exposure. Density functional theory (DFT)
calculations were carried out to provide insight into oxygen-MoS2 interaction
mechanisms. Our results showed that the influence of UV-O3 treatment on PL
depends on whether the substrate is present, as well as the number of layers.
The PL intensity of the substrate-supported MoS2 decreased dramatically with
the increase of UV-O3 treatment time and was fully quenched after 8 mins.
However, the PL intensity of the suspended flakes was less affected. 4 minutes
of UV-O3 exposure was found to be optimal to produce p-type MoS2, while
maintaining above 80% of the PL intensity and the emission wavelength, compared
to pristine flakes (intrinsically n-type). Our electrical measurements showed
that UV-O3 treatment for more than 6 minutes not only caused a reduction in the
electron density but also deteriorated the hole-dominated transport. It is
revealed that the substrate plays a critical role in the manipulation of the
electrical and optical properties of MoS2, which should be considered in future
device fabrication and applications.
In recent years, higher-order topological phases have attracted great
interest in various fields of physics. These phases have protected boundary
states at lower-dimensional boundaries than the conventional first-order
topological phases due to the higher-order bulk-boundary correspondence. In
this review, we summarize current research progress on higher-order topological
phases in both crystalline and non-crystalline systems. We firstly introduce
prototypical models of higher-order topological phases in crystals and their
topological characterizations. We then discuss effects of quenched disorder on
higher-order topology and demonstrate disorder-induced higher-order topological
insulators. We also review the theoretical studies on higher-order topological
insulators in amorphous systems without any crystalline symmetry and
higher-order topological phases in nonperiodic lattices including quasicrystals
and hyperbolic lattices, which have no crystalline counterparts. We conclude
the review by a summary of experimental realizations of higher-order
topological phases and discussions on potential directions for future study.
Synthetic antiferromagnets have great potential as skyrmion carriers in which
new properties are expected for these spin textures, owing to changed
magnetostatics and the absence of net topological charge. Here we numerically
simulate the static and dynamic behaviour of skyrmions in these systems and
clearly highlight the benefits compared to ferromagnetic single layers. In
particular, our results show a reduction of the skyrmion radius, an increase of
their velocity under current, and a vanishing of their topological deflection.
We also provide a robust and straightforward analytical model that captures the
physics of such skyrmions. Finally, by extending the model to the case of an
unbalanced SAF, we show some conditions for the system that optimise the
properties of the skyrmion for potential spintronic devices.
Topological nodal-line semimetals are always characterized by the drumhead
surface states at the open boundaries. In this paper we first derive an
analytical expression for the surface Green's function of a nodal-line
semimetal. By making use of this result, we explore the charge and spin
transport properties of a metallic chain on the surface of a nodal-line
semimetal, as functions of the gate voltage applied on the top of the material.
According to the size of the nodal loop, due to the coupling to the surface
modes, the charge conductance in the chain is found to show a robust plateau at
$e^{2}/h$, or to exhibit multiple valleys at $e^{2}/h$. Correspondingly, the
spin polarization of the transmitted current is $100\%$ at the plateau region,
or exhibits multiple peaks at nearly $100\%$. This feature can be viewed as a
transport signature of the topological nodal-line semimetals.
The nuclear spin, being much more isolated from the environment than its
electronic counterpart, enables quantum experiments with prolonged coherence
times and presents a gateway towards uncovering the intricate dynamics within
an atom. These qualities have been demonstrated in a variety of nuclear spin
qubit architectures, albeit with limited control over the direct environment of
the nuclei. As a contrasting approach, the combination of electron spin
resonance (ESR) and scanning tunnelling microscopy (STM) provides a bottom-up
platform to study the fundamental properties of nuclear spins of single atoms
on a surface. However, access to the time evolution of these nuclear spins, as
was recently demonstrated for electron spins, remained a challenge. Here, we
present an experiment resolving the nanosecond coherent dynamics of a
hyperfine-driven flip-flop interaction between the spin of an individual
nucleus and that of an orbiting electron. We use the unique local
controllability of the magnetic field emanating from the STM probe tip to bring
the electron and nuclear spins in tune, as evidenced by a set of avoided level
crossings in ESR-STM. Subsequently, we polarize both spins through scattering
of tunnelling electrons and measure the resulting free evolution of the coupled
spin system using a DC pump-probe scheme. The latter reveals a complex pattern
of multiple interfering coherent oscillations, providing unique insight into
the atom's hyperfine physics. The ability to trace the coherent hyperfine
dynamics with atomic-scale structural control adds a new dimension to the study
of on-surface spins, offering a pathway towards dynamic quantum simulation of
low-dimensional magnonics.
Van der Waals (vdW) heterostructures composed of two-dimensional (2D)
transition metal dichalcogenides (TMD) and vdW magnetic materials offer an
intriguing platform to functionalize valley and excitonic properties in
non-magnetic TMDs. Here, we report magneto-photoluminescence (PL)
investigations of monolayer (ML) MoSe$_2$ on the layered A-type
antiferromagnetic (AFM) semiconductor CrSBr under different magnetic field
orientations. Our results reveal a clear influence of the CrSBr magnetic order
on the optical properties of MoSe$_2$, such as an anomalous linear-polarization
dependence, changes of the exciton/trion energies, a magnetic-field dependence
of the PL intensities, and a valley $g$-factor with signatures of an asymmetric
magnetic proximity interaction. Furthermore, first principles calculations
suggest that MoSe$_2$/CrSBr forms a broken-gap (type-III) band alignment,
facilitating charge transfer processes. The work establishes that
antiferromagnetic-nonmagnetic interfaces can be used to control the valley and
excitonic properties of TMDs, relevant for the development of opto-spintronics
devices.
Magnetic skyrmions in atomically thin van der Waals (vdW) materials provide
an ideal playground to push skyrmion technology to the single-layer limit.
However, a major challenge is reliable skyrmion detection. Here, we show, based
on rigorous first-principles calculations, that all-electrical detection of
skyrmions in two-dimensional (2D) vdW magnets is feasible via scanning
tunneling microscopy as well as in planar tunnel junctions with straightforward
implementation into device architectures. We use the nonequilibrium Green's
function method for quantum transport in planar junctions, including
self-energy due to electrodes and working conditions, going beyond the standard
Tersoff-Hamann approximation. An extremely large noncollinear magnetoresistance
(NCMR) of above 10,000 % and a giant tunneling anisotropic magnetoresistance
(TAMR) of 200 % are observed for a vdW tunnel junction based on
graphite/Fe$_3$GeTe$_2$/germanene/graphite. The NCMR is more than two orders of
magnitude higher than that obtained for conventional transition-metal
interfaces. We trace the origin of the NCMR to spin-mixing between spin-up and
-down states of $p_z$ and $d_{z^2}$ character at the Fe and Te surface atoms
and the orbital matching effect at the interface. Our work paves the way for
all-electrical detection of skyrmionic spin textures in 2D vdW tunnel
junctions.
The interplay of topology and disorder in non-equilibrium quantum systems is
an intriguing subject. Here, we look for a suitable platform that enables an
in-depth exploration of the topic. To this end, We analyze the topological and
localization properties of a dimerized one-dimensional Kitaev chain in the
presence of an onsite quasiperiodic potential with its amplitude being
modulated periodically in time. The topological features have been explored via
computing the real-space winding numbers corresponding to both the Majorana
zero and the $\pi$ energy modes. We enumerate the scenario at different driving
frequencies. In particular, at some intermediate frequency regime, the phase
diagram concerning the zero mode involves two distinct phase transitions, one
from a topologically trivial to a non-trivial phase, and another from a
topological phase to an Anderson localized phase. On the other hand, the study
of the $\pi$ modes reveals the emergence of a unique topological phase, with
the bulk and the edges being fully localized, which may be called as the
Floquet topological Anderson phase. Furthermore, we study the localization
properties of the bulk states by computing the inverse and normalized
participation ratios, while the critical phase is ascertained by computing the
fractal dimension. We have observed extended, critical, and localized phases at
intermediate frequencies, which are further confirmed via a finite-size scaling
analysis. Finally, fully extended and localized phases are respectively
observed at lower and higher frequencies.
Hyperbolic lattices are a new type of synthetic quantum matter emulated in
circuit quantum electrodynamics and electric-circuit networks, where particles
coherently hop on a discrete tessellation of two-dimensional negatively curved
space. While real-space methods and a reciprocal-space hyperbolic band theory
have been recently proposed to analyze the energy spectra of those systems,
discrepancies between the two sets of approaches remain. In this work, we
reconcile those approaches by first establishing an equivalence between
hyperbolic band theory and $U(N)$ topological Yang-Mills theory on higher-genus
Riemann surfaces. We then show that moments of the density of states of
hyperbolic tight-binding models correspond to expectation values of Wilson
loops in the quantum gauge theory and become exact in the large-$N$ limit.
This article is the second of a three-part series that derives a
self-consistent theoretical framework of the electromechanics of arbitrarily
curved lipid membranes. Existing continuum theories commonly treat lipid
membranes as strictly two-dimensional surfaces. While this approach is
successful in many purely mechanical applications, strict surface theories fail
to capture the electric potential drop across lipid membranes, the effects of
surface charges, and electric fields within the membrane. Consequently, they do
not accurately resolve Maxwell stresses in the interior of the membrane and its
proximity. Furthermore, surface theories are generally unable to capture the
effects of distinct velocities and tractions at the interfaces between lipid
membranes and their surrounding bulk fluids. To address these shortcomings, we
apply a recently proposed dimension reduction method to the three-dimensional,
electromechanical balance laws. This approach allows us to derive an effective
surface theory without taking the limit of vanishing thickness, thus
incorporating effects arising from the finite thickness of lipid membranes. We
refer to this effective surface theory as $(2 + \delta)$-dimensional, where
$\delta$ indicates the thickness. The resulting $(2 + \delta)$-dimensional
equations of motion satisfy velocity and traction continuity conditions at the
membrane-bulk interfaces, capture the effects of Maxwell stresses, and can
directly incorporate three-dimensional constitutive models.
We study the fate of two-dimensional quadratic band crossing topological
phases under a one-dimensional quasiperiodic modulation. By employing
numerically exact methods, we fully characterize the phase diagram of the model
in terms of spectral, localization and topological properties. Unlike in the
presence of regular disorder, the quadratic band crossing is stable towards the
application of the quasiperiodic potential and most of the topological phase
transitions occur through a gap closing and reopening mechanism, as in the
homogeneous case. With a sufficiently strong quasiperiodic potential, the
quadratic band crossing point splits into Dirac cones which enables transitions
into gapped phases with Chern numbers $C=\pm1$, absent in the homogeneous
limit. This is in sharp contrast with the disordered case, where gapless
$C=\pm1$ phases can arise by perturbing the band crossing with any amount of
disorder. In the quasiperiodic case, we find that the $C=\pm1$ phases can only
become gapless for a very strong potential. Only in this regime, the subsequent
quasiperiodic-induced topological transitions into the trivial phase mirror the
well-known ``levitation and annihilation'' mechanism in the disordered case.
We perform the projector quantum Monte Carlo (QMC) simulation to study the
trion formation and quantum phase transition in the half-filled attractive
SU(3) Hubbard model on a honeycomb lattice. With increasing attractive Hubbard
interaction, our simulations demonstrate a continuous quantum phase transition
from the semimetal to charge density wave (CDW) at the critical coupling
$U_c/t=-1.52(2)$. The critical exponents $\nu=0.82(3)$ and $\eta=0.58(4)$
determined by the QMC simulation remarkably disagree with those of the $N=3$
chiral Ising universality class suggested by the effective Gross-Neveu-Yukawa
(GNY) theory, but coincide with the $N=1$ chiral Ising universality class. In
the CDW phase, we show that on-site and off-site trions coexist and the
off-site trion forms a local bond state. Our work not only illustrates the
formation of off-site trions in two-dimensional Hubbard model, but also raises
doubts about the extent of applicability of GNY model on the attractive SU(3)
Dirac fermions.
Twisted double bilayer graphene (tDBG) has emerged as an especially rich
platform for studying strongly correlated and topological states of matter. The
material features moir\'e bands that can be continuously deformed by both
perpendicular displacement field and twist angle. Here, we construct a phase
diagram representing of the correlated and topological states as a function of
these parameters, based on measurements on over a dozen tDBG devices
encompassing the two distinct stacking configurations in which the constituent
Bernal bilayer graphene sheets are rotated either slightly away from 0{\deg} or
60{\deg}. We find a hierarchy of symmetry-broken states that emerge
sequentially as the twist angle approaches an apparent optimal value of $\theta
\approx$ 1.34{\deg}. Among them, we discover a sequence of symmetry-broken
Chern insulator (SBCI) states that arise only within a narrow range of twist
angles ($\approx$ 1.33{\deg} to 1.39{\deg}). We observe an associated anomalous
Hall effect at zero field in all samples supporting SBCI states, indicating
spontaneous time-reversal symmetry breaking and possible moir\'e unit cell
enlargement at zero magnetic field.
The quantum Hall effect, fundamental in modern condensed matter physics,
continuously inspires new theories and predicts emergent phases of matter. Here
we experimentally demonstrate three types of Chern insulators with synthetic
dimensions on a programable 30-qubit-ladder superconducting processor. We
directly measure the band structures of the 2D Chern insulator along synthetic
dimensions with various configurations of Aubry-Andr\'e-Harper chains and
observe dynamical localisation of edge excitations. With these two signatures
of topology, our experiments implement the bulk-edge correspondence in the
synthetic 2D Chern insulator. Moreover, we simulate two different bilayer Chern
insulators on the ladder-type superconducting processor. With the same and
opposite periodically modulated on-site potentials for two coupled chains, we
simulate topologically nontrivial edge states with zero Hall conductivity and a
Chern insulator with higher Chern numbers, respectively. Our work shows the
potential of using superconducting qubits for investigating different
intriguing topological phases of quantum matter.
We study inhomogeneous 1+1-dimensional quantum many-body systems described by
Tomonaga-Luttinger-liquid theory with general propagation velocity and
Luttinger parameter varying smoothly in space, equivalent to an inhomogeneous
compactification radius for free boson conformal field theory. This model
appears prominently in low-energy descriptions, including for trapped ultracold
atoms, while here we present an application to quantum Hall edges with
inhomogeneous interactions. The dynamics is shown to be governed by a pair of
coupled continuity equations identical to inhomogeneous Dirac-Bogoliubov-de
Gennes equations with a local gap and solved by analytical means. We obtain
their exact Green's functions and scattering matrix using a Magnus expansion,
which generalize previous results for conformal interfaces and quantum wires
coupled to leads. Our results explicitly describe the late-time evolution
following quantum quenches, including inhomogeneous interaction quenches, and
Andreev reflections between coupled quantum Hall edges, revealing a remarkably
universal dependence on details at stationarity or at late times out of
equilibrium.
Lattice geometry continues providing exotic topological phases in condensed
matter physics. Exciting recent examples are the higher-order topological
phases, manifesting via localized lower-dimensional boundary states. Moreover,
flat electronic bands with a non-trivial topology arise in various lattices and
can hold a finite superfluid density, bounded by the Chern number $C$. Here we
consider attractive interaction in the dice lattice that hosts flat bands with
$C=\pm2$ and show that the induced superconducting state exhibits a
second-order topological phase with mixed singlet-triplet pairing. The
second-order nature of the topological superconducting phase is revealed by the
zero-energy Majorana bound states at the lattice corners. Hence, the topology
of the normal state dictates the nature of the Majorana localization. These
findings suggest that flat bands with a higher Chern number provide feasible
platforms for inducing higher-order topological superconductivity.
Although condensed matter systems usually do not have higher-form symmetries,
we show that, unlike 0-form symmetry, higher-form symmetries can emerge as
exact symmetries at low energies and long distances. In particular, emergent
higher-form symmetries at zero temperature are robust to arbitrary local UV
perturbations in the thermodynamic limit. This result is true for both
invertible and non-invertible higher-form symmetries. Therefore, emergent
higher-form symmetries are exact emergent symmetries: they are not UV
symmetries but constrain low-energy dynamics as if they were. Since phases of
matter are defined in the thermodynamic limit, this implies that a UV theory
without higher-form symmetries can have phases characterized by exact emergent
higher-form symmetries. We demonstrate this in three lattice models, the
quantum clock model and emergent $\mathbb{Z}_N$ and $U(1)$ ${p}$-gauge theory,
finding regions of parameter space with exact emergent (anomalous) higher-form
symmetries. Furthermore, we perform a generalized Landau analysis of a 2+1D
lattice model that gives rise to $\mathbb{Z}_2$ gauge theory. Using exact
emergent 1-form symmetries accompanied by their own energy/length scales, we
show that the transition between the deconfined and Higgs/confined phases is
continuous and equivalent to the spontaneous symmetry-breaking transition of a
$\mathbb{Z}_2$ symmetry, even though the lattice model has no symmetry. Also,
we show that this transition line must always contain two parts separated by
multi-critical points or other phase transitions. We discuss the physical
consequences of exact emergent higher-form symmetries and contrast them to
emergent 0-form symmetries. Lastly, we show that emergent 1-form symmetries are
no longer exact at finite temperatures, but emergent $p$-form symmetries with
$p\geq 2$ are.
Belief propagation is a well-studied algorithm for approximating local
marginals of multivariate probability distribution over complex networks, while
tensor network states are powerful tools for quantum and classical many-body
problems. Building on a recent connection between the belief propagation
algorithm and the problem of tensor network contraction, we propose a block
belief propagation algorithm for contracting two-dimensional tensor networks
and approximating the ground state of $2D$ systems. The advantages of our
method are three-fold: 1) the same algorithm works for both finite and infinite
systems; 2) it allows natural and efficient parallelization; 3) given its
flexibility it would allow to deal with different unit cells. As applications,
we use our algorithm to study the $2D$ Heisenberg and transverse Ising models,
and show that the accuracy of the method is on par with state-of-the-art
results.
Standard field theoretic formulations of composite fermion theories for the
anomalous metals that form at or near even-denominator filling fractions of the
lowest Landau level do not possess Galilei invariance. To restore Galilei
symmetry, these theories must be supplemented by "correction" terms. We study
the effect of the leading "correction" term, known as the dipole term, in the
Dirac composite fermion theory (a theory that consists of a Dirac fermion
coupled to an Abelian Chern-Simons gauge field) on quantum oscillations in the
electrical resistivity due to a periodic scalar potential about
even-denominator filling fractions. We find the dipole term to be insufficient
to resolve the systematic discrepancy, discovered in [Kamburov et. al., Phys.
Rev. Lett. 113, 196801 (2014)], between the locations of the oscillation minima
predicted by Dirac composite fermion theory without Galilei invariance and
those observed in experiment. Further, in contrast to [Hossain et al., Phys.
Rev. B 100, 041112 (2019)], we find the quantum oscillations about the
half-filled and quarter-filled lowest Landau level to have qualitatively
similar behavior. This analysis uses a mean-field approximation, in which gauge
field fluctuations are neglected. Based on this and previous analyses, we
speculate the discrepancy with experiment may be an indirect signature of the
effect of gauge field fluctuations in composite fermion theory.
The dynamics of (few) electrons dissolved in an ionic fluid--as when a small
amount of metal is added to a solution while upholding its electronic
insulation--manifests interesting properties that can be ascribed to nontrivial
topological features of particle transport (e.g., Thouless' pumps). In the
adiabatic regime, the charge distribution and the dynamics of these dissolved
electrons are uniquely determined by the nuclear configuration. Yet, their
localization into effective potential wells and their diffusivity are dictated
by how the self-interaction is modeled. In this article, we investigate the
role of self-interaction in the description of localization and transport
properties of dissolved electrons in non-stoichiometric molten salts. Although
the account for the exact (Fock) exchange strongly localizes the dissolved
electrons, decreasing their tunneling probability and diffusivity, we show that
the dynamics of the ions and of the dissolved electrons are largely
uncorrelated, irrespective of the degree to which the electron self-interaction
is treated, and in accordance with topological arguments.
We theoretically study the quantum transport in a three-dimensional spin-1
chiral fermion system in the presence of coulomb impurities based on the
self-consistent Born approximation. We find that the flat-band states
anomalously enhance the screening effect, and the electrical conductivity is
increased in the low-energy region. It is also found that reducing the
screening length leads to an increase in the forward scattering contribution
and, thus, an increase in the vertex correction in the high-energy region.
We investigate optically induced magnetization in Floquet-Weyl semimetals
generated by irradiation of a circularly-polarized continuous-wave laser from
the group II-V narrow gap semiconductor Zn$_3$As$_2$ in a theoretical manner.
Here, this trivial and nonmagnetic crystal is driven by the laser with a nearly
resonant frequency with a band gap to generate two types of Floquet-Weyl
semimetal phases composed of different spin states. These two phases host
nontrivial two-dimensional surface states pinned to the respective pairs of the
Weyl points. By numerically evaluating the laser-induced transient
carrier-dynamics, it is found that both spins are distributed in an uneven
manner on the corresponding surface states due to significantly different
excitation probabilities caused by the circularly-polarized laser with the
nearly resonant frequency. It is likely that such spin-polarized surface states
produce surface magnetization, and furthermore the inverse Faraday effect also
contributes almost as much as the spin magnetization. To be more specific,
excited carries with high density of the order of $10^{21}\: {\rm cm}^{-3}$ are
generated by the laser with electric field strength of a few MV/cm to result in
the surface magnetization that becomes asymptotically constant with respect to
time, around 1 mT. The magnitude and the direction of it depend sharply on both
of the intensity and frequency of the driving laser, which would be detected by
virtue of the magneto-optic Kerr effect.
The existence of fractionally quantized topological corner states serves as a
key indicator for two-dimensional second-order topological insulators (SOTIs),
yet has not been experimentally observed in realistic materials. Here, based on
effective model analysis and symmetry arguments, we propose a strategy for
achieving SOTI phases with in-gap corner states in two dimensional systems with
antiferromagnetic (AFM) order. We uncover by a minimum lattice model that the
band topology originates from the interplay between intrinsic spin-orbital
coupling and interlayer AFM exchange interactions. Using first principles
calculations, we show that the 2D AFM SOTI phases can be realized in
(MnBi$_2$Te$_4$)(Bi$_2$Te$_3$)$_{m}$ films. Moreover, we demonstrate that the
nontrivial corner states are linked to rotation topological invariants under
three-fold rotation symmetry $C_3$, resulting in $C_3$-symmetric SOTIs with
corner charges fractionally quantized to $\frac{n}{3} \lvert e \rvert $ (mod
$e$). Due to the great recent achievements in
(MnBi$_2$Te$_4$)(Bi$_2$Te$_3$)$_{m}$ systems, our results providing reliable
material candidates for experimentally accessible AFM higher-order band
topology would draw intense attentions.
Two-dimensional moir\'e materials have emerged as the most versatile
platforms for realizing quantum phases of electrons. Here, we explore the
stability origins of correlated states in WSe2/WS2 moir\'e superlattices. We
find that ultrafast electronic excitation leads to melting of the Mott states
on time scales five times longer than predictions from the charge hopping
integrals and the melting rates are thermally activated, with activation
energies of 18 and 13 meV for the one- and two-hole Mott states, respectively,
suggesting significant electron-phonon coupling. DFT calculation of the
one-hole Mott state confirms polaron formation and yields a hole-polaron
binding energy of 16 meV. These findings reveal a close interplay of
electron-electron and electron-phonon interactions in stabilizing the polaronic
Mott insulators at transition metal dichalcogenide moir\'e interfaces.
Honeycomb layered frameworks with metallophilic bilayers have garnered
traction in various disciplines due to their unique configuration and numerous
physicochemical and topological properties, such as fast ionic conduction,
coordination chemistry, and structural defects. These properties make them
attractive for energy storage applications, leading to increased attention
towards their metallophilic bilayer arrangements. This Review focuses on recent
advancements in this field, including characterisation techniques like X-ray
absorption spectroscopy and high-resolution transmission electron microscopy,
particularly for silver-based oxides. It also highlights strategies related to
cationic-deficient phases induced by topology or temperature, expanding the
compositional space of honeycomb layered frameworks with a focus on cationic
bilayer architectures. The Review further discusses theoretical approaches for
understanding the bilayered structure, especially concerning critical phenomena
at the monolayer-bilayer phase transition. Honeycomb layered frameworks are
described as optimised lattices within the congruent sphere packing problem,
equivalent to a specific two-dimensional conformal field theory. The
monolayer-bilayer phase transition involves a 2D-to-3D crossover. Overall, this
Review aims to provide a panoramic view of honeycomb layered frameworks with
metallophilic bilayers and their potential applications in the emerging field
of quantum matter. It is valuable for recent graduates and experts alike across
diverse fields, extending beyond materials science and chemistry.
We investigate the interplay between altermagnetic spin-splitting and
nonsymmorphic symmetries using the space group no. 62 as a testbed. Studying
different magnetic orders by means of first-principles calculations, we find
that the altermagnetism (AM) is present in the C-type magnetic configuration
while it is absent for the G-type and A-type configurations due to different
magnetic space group types. The nonsymmorphic symmetries constrain the system
to a four-fold degeneracy at the border of the Brillouin zone with semi-Dirac
dispersion. In the case of large hybridization as for transition metal
pnictides, the interplay between AM and nonsymmorphic symmetries generates an
intricate network of several crossings and anticrossings that we describe in
terms of semi-Dirac points and glide symmetries. When we add the spin-orbit
coupling (SOC), we find a Neel-vector dependent spin-orbit splitting at the
time-reversal invariant momenta points since the magnetic space groups depend
on the Neel vector. The magnetic space group type-I produces antiferromagnetic
hourglass electrons that disappear in the type-III. When the Neel vector is
along x, we observe a glide-protected crossing that could generate a nodal-line
in the altermagnetic phase. The SOC splits the remaining band crossings and
band anticrossings producing a large anomalous Hall effect in all directions
excluding the Neel-vector direction
Steady illumination of a non-centrosymmetric semiconductor results in a bulk
photovoltaic current, which is contributed by real-space displacements
(`shifts') of charged quasiparticles as they transit between Bloch states. The
shift induced by interband excitation via absorption of photons has received
the prevailing attention. However, this excitation-induced shift can be far
outweighed ($\ll$) by the shift induced by intraband relaxation, or by the
shift induced by radiative recombination of electron-hole pairs. This
outweighing ($\ll$) is attributed to (i) time-reversal-symmetric, intraband
Berry curvature, which results in an anomalous shift of quasiparticles as they
scatter with phonons, as well as to (ii) topological singularities in the
interband Berry phase (`optical vortices'), which makes the photovoltaic
current extraordinarily sensitive to the linear polarization vector of the
light source. Both (i-ii) potentially lead to nonlinear conductivities of order
$mAV^{-2}$, without finetuning of the incident radiation frequency, band gap,
or joint density of states.
Magnetic skyrmions are vortex-like quasiparticles characterized by long
lifetime and remarkable topological properties. That makes them a promising
candidate for the role of information carriers in magnetic information storage
and processing devices. Although considerable progress has been made in
studying skyrmions in classical systems, little is known about the quantum
case: quantum skyrmions cannot be directly observed by probing the local
magnetization of the system, and the notion of topological protection is
elusive in the quantum realm. Here, we explore the potential robustness of
quantum skyrmions in comparison to their classical counterparts. We
theoretically analyze the dynamics of a quantum skyrmion subject to local
projective measurements and demonstrate that the properties of the skyrmionic
quantum state change very little upon external perturbations. We further show
that by performing repetitive measurements on a quantum skyrmion, it can be
completely stabilized through an analog of the quantum Zeno effect.
Skyrmionic devices exhibit energy-efficient and high-integration data storage
and computing capabilities due to their small size, topological protection, and
low drive current requirements. So, to realize these devices, an extensive
study, from fundamental physics to practical applications, becomes essential.
In this article, we present an exhaustive review of the advancements in
understanding the fundamental physics behind magnetic skyrmions and the novel
data storage and computing technologies based on them. We begin with an
in-depth discussion of fundamental concepts such as topological protection,
stability, statics and dynamics essential for understanding skyrmions,
henceforth the foundation of skyrmion technologies. For the realization of
CMOS-compatible skyrmion functional devices, the writing and reading of the
skyrmions are crucial. We discuss the developments in different writing schemes
such as STT, SOT, and VCMA. The reading of skyrmions is predominantly achieved
via two mechanisms: the Magnetoresistive Tunnel Junction (MTJ) TMR effect and
topological resistivity (THE). So, a thorough investigation into the Skyrmion
Hall Effect, topological properties, and emergent fields is also provided,
concluding the discussion on skyrmion reading developments. Based on the
writing and reading schemes, we discuss the applications of the skyrmions in
conventional logic, unconventional logic, memory applications, and neuromorphic
computing in particular. Subsequently, we present an overview of the potential
of skyrmion-hosting Majorana Zero Modes (MZMs) in the emerging Topological
Quantum Computation and helicity-dependent skyrmion qubits.
Here we present the family of titanium-based kagome metals of the form
LnTi$_3$Bi$_4$ (Ln: La...Gd$^{3+}$, Eu$^{2+}$, Yb$^{2+}$). Single crystal
growth methods are presented alongside detailed magnetic and thermodynamic
measurements. The orthorhombic (Fmmm) LnTi$_3$Bi$_4$ family of compounds
exhibit slightly distorted titanium-based kagome nets interwoven with zig-zag
lanthanide-based (Ln) chains. Crystals are easily exfoliated parallel to the
kagome sheets and angular resolved photoemission (ARPES) measurements highlight
the intricacy of the electronic structure in these compounds, with Dirac points
existing at the Fermi level. The magnetic properties and the associated
anisotropy emerge from the quasi-1D zig-zag chains of Ln, and impart a wide
array of magnetic ground states ranging from anisotropic ferromagnetism to
complex antiferromagnetism with a cascade of metamagnetic transitions. Kagome
metals continue to provide a rich direction for the exploration of magnetic,
topologic, and highly correlated behavior. Our work here introduces the
LnTi$_3$Bi$_4$ compounds to augment the continuously expanding suite of complex
and interesting kagome materials.

Found 4 papers in prl Optical mirrors determine cavity properties by means of light reflection. Imperfect reflection gives rise to open cavities with photon loss. We study an open cavity made of atom-dimer mirrors with a tunable reflection spectrum. We find that the atomic cavity shows anti-$\mathcal{PT}$ symmetry. The a… In direct-drive inertial confinement fusion, the laser bandwidth reduces the laser imprinting seed of hydrodynamic instabilities. The impact of varying bandwidth on the performance of direct-drive DT-layered implosions was studied in targets with different hydrodynamic stability properties. The stab… When zeros appear in the Green function, as in strongly correlated systems, the invariant ${N}_{3}$ for the two-dimensional quantum anomalous Hall insulator not necessarily encodes a topological invariant of the ground state, in contrast to expectations. Oscillatory behavior is ubiquitous in out-of-equilibrium systems showing spatiotemporal pattern formation. Starting from a linear large-scale oscillatory instability—a conserved-Hopf instability—that naturally occurs in many active systems with two conservation laws, we derive a corresponding amplit…
