Found 30 papers in cond-mat As early as 1867, two years after the introduction of the concept of entropy
by Clausius, Maxwell showed that the limitations imposed by the second law of
thermodynamics depend on the information that one possesses about the state of
a physical system. A "very observant and neat-fingered being", later on named
Maxwell demon by Kelvin, could arrange the molecules of a gas and induce a
temperature or pressure gradient without performing work, in apparent
contradiction to the second law. One century later, Landauer claimed that
"information is physical", and showed that certain processes involving
information, like overwriting a memory, need work to be completed and are
unavoidably accompanied by heat dissipation. Thermodynamics of information
analyzes this bidirectional influence between thermodynamics and information
processing. The seminal ideas that Landauer and Bennett devised in the 1970s
have been recently reformulated in a more precise and general way by realizing
that informational states are out of equilibrium and applying new tools from
non-equilibrium statistical mechanics.
Over the last decade, there have been considerable efforts to observe
non-abelian quasi-particles in novel quantum materials and devices. These
efforts are motivated by the goals of demonstrating quantum statistics of
quasi-particles beyond those of fermions and bosons and of establishing the
underlying science for the creation of topologically protected quantum bits. In
this review, we focus on efforts to create topological superconducting phases
hosting Majorana zero modes. We consider the lessons learned from existing
experimental efforts, which are motivating both improvemensts to current
platforms and exploration of new approaches. Although the experimental
detection of non-abelian quasi-particles remains challenging, the knowledge
gained thus far and the opportunities ahead offer high potential for discovery
and advances in this exciting area of quantum physics.
The interplay between dissipation and correlation can lead to new emergent
phenomena. Here we study non-equilibrium phases of matter with robust
topological degeneracy of steady states, which is a generalization of the
ground-state topological degeneracy of closed systems. Specifically, we
construct two representative Lindbladians using engineered dissipation, and
exactly solve the steady states with topological degeneracy. We find that while
the degeneracy is fragile under noise in two dimensions, it is stable in three
dimensions, where a genuine many-body phase with topological degeneracy is
realized. We identify universal features of dissipative topological physics
such as the deconfined emergent gauge field and slow relaxation dynamics of
topological defects. The transition from a topologically ordered phase to a
trivial phase is also investigated via numerical simulation. Our work
highlights the essential difference between ground-state topological order in
closed systems and steady-state topological order in open systems.
In graphene, the approximate SU(4) symmetry associated with the spin and
valley degrees of freedom in the quantum Hall (QH) regime is reflected in the
4-fold degeneracy of graphene's Landau levels (LL's). Interactions and the
Zeeman effect break such approximate symmetry and lift the corresponding
degeneracy of the LLs. We study how the breaking of the approximate SU(4)
symmetry affects the properties of graphene's QH edge modes located in
proximity to a superconductor. We show how the lifting of the 4-fold degeneracy
qualitatively modifies the transport properties of the QH-superconductor
heterojunction. For the zero LL, by placing the edge modes in proximity to a
superconductor, it is in principle possible to realize a 1D topological
superconductor supporting Majoranas in the presence of sufficiently strong
Zeeman field. We estimate the topological gap of such a topological
superconductor and relate it to the properties of the QH-superconductor
interface.
Recent experiments indicate that crystalline graphene multilayers exhibit
much of the richness of their twisted counterparts, including cascades of
symmetry-broken states and unconventional superconductivity. Interfacing Bernal
bilayer graphene with a WSe$_2$ monolayer was shown to dramatically enhance
superconductivity -- suggesting that proximity-induced spin-orbit coupling
plays a key role in promoting Cooper pairing. Motivated by this observation, we
study the phase diagram of spin-orbit-coupled rhombohedral trilayer graphene
via self-consistent Hartree-Fock simulations, elucidating the interplay between
displacement field effects, long-range Coulomb repulsion, short-range (Hund's)
interactions, and substrate-induced Ising spin-orbit coupling. In addition to
generalized Stoner ferromagnets, we find various flavors of intervalley
coherent ground states distinguished by their transformation properties under
electronic time reversal, ${\rm C}_3$ rotations, and an effective anti-unitary
symmetry. We pay particular attention to broken-symmetry phases that yield
Fermi surfaces compatible with zero-momentum Cooper pairing, identifying
promising candidate orders that may support spin-orbit-enhanced
superconductivity.
Two-dimensional van der Waals materials have become an established platform
to engineer flat bands which can lead to strongly-correlated emergent
phenomena. In particular, the family of Ta dichalcogenides in the 1\textit{T}
phase presents a star-of-David charge density wave that creates a flat band at
the Fermi level. For TaS$_2$ and TaSe$_2$ this flat band is at half filling
leading to a magnetic insulating phase. In this work, we theoretically
demonstrate that ligand substitution in the TaSe$_{2-x}$Te$_x$ system produces
a transition from the magnetic insulator to a non-magnetic metal in which the
flat band gets doped away from half-filling. For $x\in[{0.846},{1.231}]$ the
spin-polarized flat band is self-doped and the system becomes a magnetic metal.
In this regime, we show that attractive interactions promote three different
spin-triplet superconducting phases as a function of $x$, corresponding to a
nodal f-wave and two topologically-different chiral p-wave superconducting
phases. Our results establish monolayer TaSe$_{2-x}$Te$_{x}$ as a promising
platform for correlated flat band physics leading to unconventional
superconducting states.
We investigate the extrinsic spin-orbit torque (SOT) on the surface of
topological insulators (TIs), which are characterized by two-dimensional warped
Dirac surface states, in the presence of an in-plane magnetization. The
interplay between extrinsic spin-orbit scattering and the in-plane
magnetization results in a net spin density leading to a SOT. Previous theory
suggested that the SOT could only be generated by an out-of-plane magnetic
field component, and any in-plane magnetic contribution could be gauged away.
However, we demonstrate theoretically that with an in-plane magnetization, the
SOT can be finite in TIs due to extrinsic spin-orbit scattering. In the case of
a TI model with a linear dispersion relation, the skew scattering term is zero,
and the extrinsic spin-orbit scattering influences the side-jump scattering,
leading to a finite SOT in TIs. However, when considering the warping term,
finite intrinsic and skew scattering terms will arise, in addition to
modifications to other scattering terms. We further show that the SOT depends
on the azimuthal angles of the magnetization and an external electric field. By
adjusting the extrinsic spin-orbit strength, Fermi energy, magnetization
strength and warping strength, the resulting SOTs can be maximized. These
findings shed light on the interplay between spin-orbit coupling and
magnetization in TIs, offering insights into the control and manipulation of
spin currents in these systems.
Slip avalanches are ubiquitous phenomena occurring in 3D materials under
shear strain and their study contributes immensely to our understanding of
plastic deformation, fragmentation, and earthquakes. So far, little is known
about the role of shear strain in 2D materials. Here we show some evidence of
two-dimensional slip avalanches in exfoliated rhombohedral MoS2, triggered by
shear strain near the threshold level. Utilizing interfacial polarization in
3R-MoS2, we directly probe the stacking order in multilayer flakes and discover
a wide variety of polarization domains with sizes following a power-law
distribution. These findings suggest slip avalanches can occur during the
exfoliation of 2D materials, and the stacking orders can be changed via shear
strain. Our observation has far-reaching implications for developing new
materials and technologies, where precise control over the atomic structure of
these materials is essential for optimizing their properties as well as for our
understanding of fundamental physical phenomena.
Continuous phase transitions in equilibrium statistical mechanics were
successfully described 50 years ago with the development of the renormalization
group framework. This framework was initially developed in the context of phase
transitions whose universal properties are captured by the long wavelength (and
long time) fluctuations of a Landau order parameter field. Subsequent
developments include a straightforward generalization to a class of $T = 0$
phase transitions driven by quantum fluctuations. In the last 2 decades it has
become clear that there is a vast landscape of quantum phase transitions where
the physics is not always usefully (or sometimes cannot be) formulated in terms
of fluctuations of a Landau order parameter field. A wide class of such phase
transitions - dubbed deconfined quantum critical points - involve the emergence
of fractionalized degrees of freedom coupled to emergent gauge fields. Here I
review some salient aspects of these deconfined critical points.
Dirac semi-metal with magnetic atoms as constituents delivers an interesting
platform to investigate the interplay of Fermi surface (FS) topology, electron
correlation, and magnetism. One such family of semi-metal is YbMn$Pn_2$ ($Pn$ =
Sb, Bi), which is being actively studied due to the intertwined spin and charge
degrees of freedom. In this Letter, we investigate the relationship between the
magnetic/crystal structures and FS topology of YbMnSb$_2$ using single crystal
x-ray diffraction, neutron scattering, magnetic susceptibility,
magnetotransport measurement and complimentary DFT calculation. Contrary to
previous reports, the x-ray and neutron diffraction reveal that YbMnSb$_2$
crystallizes in an orthorhombic $Pnma$ structure with notable anti-phase
displacement of the magnetic Mn ions that increases in magnitude upon cooling.
First principles DFT calculation reveals a reduced Brillouin zone and more
anisotropic FS of YbMnSb$_2$ compared to YbMnBi$_2$ as a result of the
orthorhombicity. Moreover, the hole type carrier density drops by two orders of
magnitude as YbMnSb$_2$ orders antiferromagnetically indicating band folding in
magnetic ordered state. In addition, the Landau level fan diagram yields a
non-trivial nature of the SdH quantum oscillation frequency arising from the
Dirac-like Fermi pocket. These results imply that YbMnSb$_2$ is an ideal
platform to explore the interplay of subtle lattice distortion, magnetic order,
and topological transport arising from relativistic quasiparticles.
The low crystal symmetry of rhenium disulphide (ReS2) leads to the emergence
of dichroic optical and optoelectronic response, absent in other layered
transition metal dichalcogenides, which could be exploited for device
applications requiring polarization resolution. To date, spectroscopy studies
on the optical response of ReS2 have relied almost exclusively in
characterization techniques involving optical detection, such as
photoluminescence, absorbance, or reflectance spectroscopy. However, to realize
the full potential of this material, it is necessary to develop knowledge on
its optoelectronic response with spectral resolution. In this work, we study
the polarization-dependent photocurrent spectra of few-layer ReS2
photodetectors, both in room conditions and at cryogenic temperature. Our
spectral measurements reveal two main exciton lines at energies matching those
reported for optical spectroscopy measurements, as well as their excited
states. Moreover, we also observe an additional exciton-like spectral feature
with a photoresponse intensity comparable to the two main exciton lines. We
attribute this feature, not observed in earlier photoluminescence measurements,
to a non-radiative exciton transition. The intensities of the three main
exciton features, as well as their excited states, modulate with linear
polarization of light, each one acquiring maximal strength at a different
polarization angle. We have performed first-principles exciton calculations
employing the Bethe-Salpeter formalism, which corroborate our experimental
findings. Our results bring new perspectives for the development of ReS2-based
nanodevices.
Momentum-matched type II van der Waals heterostructures (vdWHs) have been
designed by assembling layered two-dimensional semiconductors (2DSs) with
special band-structure combinations - that is, the valence band edge at the
Gamma point (the Brillouin-zone center) for one 2DS and the conduction band
edge at the Gamma point for the other [Ubrig et al., Nat. Mater. 19, 299
(2020)]. However, the band offset sizes, band-alignment types, and whether
momentum matched or not, all are affected by the interfacial effects between
the component 2DSs, such as the quasichemical-bonding (QB) interaction between
layers and the electrical dipole moment formed around the vdW interface. Here,
based on density-functional theory calculations, first we probe the interfacial
effects (including different QBs for valence and conduction bands, interface
dipole, and, the synergistic effects of these two aspects) on band-edge
evolution in energy and valley (location in the Brillouin zone) and the
resulting changes in band alignment and momentum matching for a typical vdWH of
monolayer InSe and bilayer WS2, in which the band edges of subsystems satisfy
the special band-structure combination for a momentum-matched type II vdWH.
Then, based on the conclusions of the studied interfacial effects, we propose a
practical screening method for robust momentum-matched type II vdWHs. This
practical screening method can also be applied to other band alignment types.
Our current study opens a way for practical screening and designing of vdWHs
with robust momentum-matching and band alignment type.
Charge-transfer excitations are of paramount importance for understanding the
electronic structure of copper-oxide based high-temperature superconductors. In
this study, we investigate the response of a
Bi$_2$Sr$_2$CaCu$_2$O$_{\mathrm{8}+ \delta}$ crystal to the charge
redistribution induced by an infrared ultrashort pulse. Element-selective
time-resolved core-level photoelectron spectroscopy with a high energy
resolution allows disentangling the dynamics of oxygen ions with different
coordination and bonds thanks to their different chemical shifts. Our
experiment shows that the O\,$1s$ component arising from the Cu-O planes is
significantly perturbed by the infrared light pulse. Conversely, the apical
oxygen, also coordinated with Sr ions in the Sr-O planes, remains unaffected.
This result highlights the peculiar behavior of the electronic structure of the
Cu-O planes. It also unlocks the way to study the out-of-equilibrium electronic
structure of copper-oxide-based high-temperature superconductors by identifying
the O\,$1s$ core-level emission originating from the oxygen ions in the Cu-O
planes. This ability could be critical to gain information about the
strongly-correlated electron ultrafast dynamical mechanisms in the Cu-O plane
in the normal and superconducting phases.
Characterizing the anchoring properties of smectic liquid crystals (LCs) in
contact with bacterial solutions is crucial for developing biosensing
platforms. In this study, we investigate the anchoring properties of a smectic
LC when exposed to Bacillus Subtilis and Escherichia coli bacterial solutions
using interfaces with known anchoring properties. By monitoring the optical
response of the smectic film, we successfully distinguish different types of
bacteria, leveraging the distinct changes in the LC's response. Through a
comprehensive analysis of the interactions between bacterial proteins and the
smectic interface, we elucidate the potential underlying mechanisms responsible
for these optical changes. Additionally, we introduce the utilization of
topological defects; the focal conic domains (FCDs), at the smectic interface
as an indicative measure of the bacterial concentration. Our findings
demonstrate the significant potential of smectic LCs and their defects for
biosensing applications and contribute to our understanding of bacteria- LC
interactions, paving the way for advancements in pathogen detection and
protein-based sensing.
Understanding the origin of damping mechanisms in magnetization dynamics of
metallic ferromagnets is a fundamental problem for nonequilibrium many-body
physics of systems where quantum conduction electrons interact with localized
spins assumed to be governed by the classical Landau-Lifshitz-Gilbert (LLG)
equation. It is also of critical importance for applications as damping affects
energy consumption and speed of spintronic and magnonic devices. Since the
1970s, a variety of linear-response and scattering theory approaches have been
developed to produce widely used formulas for computation of
spatially-independent Gilbert scalar parameter as the magnitude of the Gilbert
damping term in the LLG equation. The largely-unexploited-for-this-purpose
Schwinger-Keldysh field theory (SKFT) offers additional possibilities, such as
rigorously deriving an extended LLG equation by integrating quantum electrons
out. Here we derive such equation whose Gilbert damping for metallic
ferromagnets in $d=1$-$3$ dimensions is nonlocal-i.e., dependent on position of
all localized spins at a given time-and nonuniform, even if all localized spins
are collinear and spin-orbit coupling (SOC) is absent. This is in sharp
contrast to standard lore, where nonlocal damping is possible only if localized
spins are noncollinear, while SOC is required to obtain a standard Gilbert
damping scalar parameter for collinear localized spins. The same mechanism,
which is physically due to retarded response of conduction electronic spins to
the motion of localized spins, generates wavevector-dependent damping on spin
waves, whereas nonzero SOC makes nonlocal damping anisotropic. Our analytical
formulas, with their nonlocality being more prominent in low spatial dimensions
$d \le 2$, are fully corroborated by numerically exact $d=1$ quantum-classical
simulations.
An axion insulator is a three-dimensional (3D) topological insulator (TI), in
which the bulk maintains the time-reversal symmetry or inversion symmetry but
the surface states are gapped by surface magnetization. The axion insulator
state has been observed in molecular beam epitaxy (MBE)-grown magnetically
doped TI sandwiches and exfoliated intrinsic magnetic TI MnBi2Te4 flakes with
an even number layer. All these samples have a thickness of ~10 nm, near the
2D-to-3D boundary. The coupling between the top and bottom surface states in
thin samples may hinder the observation of quantized topological
magnetoelectric response. Here, we employ MBE to synthesize magnetic TI
sandwich heterostructures and find that the axion insulator state persists in a
3D sample with a thickness of ~106 nm. Our transport results show that the
axion insulator state starts to emerge when the thickness of the middle undoped
TI layer is greater than ~3 nm. The 3D hundred-nanometer-thick axion insulator
provides a promising platform for the exploration of the topological
magnetoelectric effect and other emergent magnetic topological states, such as
the high-order TI phase.
For quantum electronics, the possibility to finely tune the properties of
magnetic topological insulators (TIs) is a key issue. We studied solid
solutions between two isostructural Z$_2$ TIs, magnetic MnBi$_2$Te$_4$ and
nonmagnetic GeBi$_2$Te$_4$, with Z$_2$ invariants of 1;000 and 1;001,
respectively. For high-quality, large mixed crystals of
Ge$_x$Mn$_{1-x}$Bi$_2$Te$_4$, we observed linear x-dependent magnetic
properties, composition-independent pairwise exchange interactions along with
an easy magnetization axis. The bulk band gap gradually decreases to zero for
$x$ from 0 to 0.4, before reopening for $x>0.6$, evidencing topological phase
transitions (TPTs) between topologically nontrivial phases and the semimetal
state. The TPTs are driven purely by the variation of orbital contributions. By
tracing the x-dependent $6p$ contribution to the states near the fundamental
gap, the effective spin-orbit coupling variation is extracted. As $x$ varies,
the maximum of this contribution switches from the valence to the conduction
band, thereby driving two TPTs. The gapless state observed at $x=0.42$ closely
resembles a Dirac semimetal above the Neel temperature and shows a magnetic gap
below, which is clearly visible in raw photoemission data. The observed
behavior of the Ge$_x$Mn$_{1-x}$Bi$_2$Te$_4$ system thereby demonstrates an
ability to precisely control topological and magnetic properties of TIs.
By performing first-principles calculations in conjunction with Monte Carlo
simulations, we systematically investigated the frustrated magnetic states
induced by in-plane compressive strain in LiCrTe$_{2}$. Our calculations
support that the magnetic ground state of LiCrTe$_{2}$ crystal is A-type
antiferromagnetic (AFM), with an in-plane ferromagnetic (FM) state and
interlayer AFM coupling. Furthermore, it is found that compressive strain can
significantly alter the magnetic interactions, giving rise to a transition from
an in-plane FM to an AFM state, undergoing a helimagnetic phase. Remarkably, a
highly frustrated helimagnetic state with disordered spin spirals under
moderate strain arises from the competition between spiral propagation modes
along distinct directions. In addition, various topological spin defects emerge
in this frustrated helimagnetic phase, which are assembled from various domain
wall units. These topological defects can be further tuned with external
magnetic fields. Our calculations not only uncover the origin of exotic
frustrated magnetism in triangular lattice magnetic systems, but also offer a
promising route to engineer the frustrated and topological magnetic state,
which is of significance in both fundamental research and technological
applications.
Onsite gain-loss induced topological braiding principles of non-Hermitian
energy bands is theoretically formulated in multiband lattice models with
Hermitian hopping amplitudes. Braid phase transition occurs when the gain-loss
parameter is tuned across exceptional point degeneracies. Laboratory realizable
effective-Hamiltonians are proposed to realize braid groups $\mathbb{B}_2$ and
$\mathbb{B}_3$ of two and three bands respectively. While $\mathbb{B}_2$ is
trivially Abelian, the group $\mathbb{B}_3$ features non-Abelian braiding and
energy permutation. Phase diagrams with respect to lattice parameters to
realize braid group generators and their non-commutativity are shown. The
proposed theory is conducive to synthesize exceptional materials for
applications in topological quantum photonic computation and information
processing.
We study the effect of disorder in systems having a non-trivial Euler class.
As these recently proposed multi-gap topological phases come about by braiding
non-Abelian charged band nodes residing between different bands to induce
stable pairs within isolated band subspaces, novel properties that include a
finite critical phase under the debraiding to a metal rather than a transition
point and a modified stability may be expected when the disorder preserves the
underlying $C_2\cal{T}$ or $\cal{P}\cal{T}$ symmetry on average. Employing
elaborate numerical computations, we verify the robustness of associated
topology by evaluating the changes in the average densities of states and
conductivities for different types of disorders. Upon performing a scaling
analysis around the corresponding quantum critical points we retrieve a
universality for the localization length exponent of $\nu = 1.4 \pm 0.1$ for
Euler-protected phases, relating to 2D percolation models. We generically find
that quenched disorder drives Euler semimetals into critical metallic phases.
Finally, we show that magnetic disorder can also induce topological transitions
to quantum anomalous Hall plaquettes with local Chern numbers determined by the
initial value of the Euler invariant.
We study the Atiyah-Hirzebruch spectral sequence (AHSS) for equivariant
K-theory in the context of band theory. Various notions in the band theory such
as irreducible representations at high-symmetric points, the compatibility
relation, topological gapless and singular points naturally fits into the AHSS.
As an application of the AHSS, we get the complete list of topological
invariants for 230 space groups without time-reversal or particle-hole
invariance. We find that a lot of torsion topological invariants appear even
for symmorphic space groups.
We propose that symmetry protected topological (SPT) phases with crystalline
symmetry are formulated by equivariant generalized homologies $h^G_n(X)$ over a
real space manifold $X$ with $G$ a crystalline symmetry group. The
Atiyah-Hirzebruch spectral sequence unifies various notions in crystalline SPT
phases such as the layer construction, higher-order SPT phases and
Lieb-Schultz-Mattis type theorems. Our formulation is applicable to interacting
systems with onsite and crystalline symmetries as well as free fermions.
Global symmetries that define the number of low energy degrees of freedom
have profound consequences on universal properties near topological quantum
critical points and in other gapless or nearly gapless states of emergent
fermions. We take a $Z_2$ global symmetry (such as time-reversal) as an example
to study its effect on thermodynamic and transport properties. Although the
thermal entropy density of $Z_2$ symmetric systems is simply twice of their
counterparts without any global symmetries or the $Z_1$ class, the temperature
dependence of thermal conductivity $\kappa$ is distinctly and drastically
different for different symmetries. For systems with dynamic exponent $z=1$, in
the $Z_2$ symmetric class, we have $\kappa\propto T^{-(d-1)}$ in the quantum
critical regime near weakly interacting fixed points, while for systems with no
global symmetries (i.e., the $Z_1$ class), we have $\kappa\propto T^{-(d+3)}$,
with $d$ being the spatial dimension. Only near strong coupling fixed points,
both cases with or without $Z_2$ global symmetries follow the same scaling
function, $\kappa \propto T^{d-1}$. These distinct scalings of thermal
conductivity can also appear in gapless surface Majorana states.
Exfoliated magnetic 2D materials enable versatile tuning of magnetization,
e.g., by gating or providing proximity-induced exchange interaction. However,
their electronic band structure after exfoliation has not been probed, most
likely due to their photochemical sensitivity. Here, we provide micron-scale
angle-resolved photoelectron spectroscopy of the exfoliated intralayer
antiferromagnet MnPS$_3$ above and below the N\'{e}el temperature down to one
monolayer. The favorable comparison with density functional theory calculations
enables to identify the orbital character of the observed bands. Consistently,
we find pronounced changes across the N\'{e}el temperature for bands that
consist of Mn 3d and 3p levels of adjacent S atoms. The deduced orbital mixture
indicates that the superexchange is relevant for the magnetic interaction.
There are only minor changes between monolayer and thicker films demonstrating
the predominant 2D character of MnPS$_3$. The novel access is transferable to
other MPX$_3$ materials (M: transition metal, P: phosphorus, X: chalcogenide)
providing a multitude of antiferromagnetic arrangements.
Thermodynamics is a science concerning the state of a system, whether it is
stable, metastable, or unstable. The combined law of thermodynamics derived by
Gibbs about 150 years ago laid the foundation of thermodynamics. In Gibbs
combined law, the entropy production due to internal processes was not
included, and the 2nd law was thus practically removed from the Gibbs combined
law, so it is only applicable to systems under equilibrium. Gibbs further
derived the classical statistical thermodynamics in terms of the probability of
configurations in a system. With the quantum mechanics (QM) developed, the
QM-based statistical thermodynamics was established and connected to classical
statistical thermodynamics at the classical limit as shown by Landau. The
development of density function theory (DFT) by Kohn and co-workers enabled the
QM prediction of properties of the ground state of a system. On the other hand,
the entropy production due to internal processes in non-equilibrium systems was
studied separately by Onsager and Prigogine and co-workers. The digitization of
thermodynamics was developed by Kaufman in the framework of the CALPHAD
modeling of individual phases. Our recently termed zentropy theory integrates
DFT and statistical mechanics through the replacement of the internal energy of
each individual configuration by its DFT-predicted free energy. Furthermore,
through the combined law of thermodynamics with the entropy production as a
function of internal degrees of freedom, it is shown that the kinetic
coefficient matrix of independent internal processes is diagonal with respect
to the conjugate potentials in the combined law, and the cross phenomena
represented by the phenomenological Onsager reciprocal relationships are due to
the dependence of the conjugate potential of the molar quantity in a flux on
nonconjugate potentials.
Recent experimental discovery of flavor symmetry breaking metallic phases in
Bernal-stacked bilayer graphene points to the strongly interacting nature of
electrons near the top (bottom) of its valence (conduction) band.
Superconductivity was also observed in between these symmetry breaking phases
when the graphene bilayer is placed under a small in-plane magnetic field or in
close proximity to a monolayer WSe$_2$ substrate. Here we address the
correlated nature of the band edge electrons and obtain the quantum phase
diagram of their many-body ground states incorporating the effect of proximity
induced spin-orbit coupling. We find that in addition to the spin/valley flavor
polarized half and quarter metallic states, two types of intervalley coherent
phases emerge near the phase boundaries between the flavor polarized metals.
Both spin-orbit coupling and in-plane magnetic field disfavor the
spin-unpolarized valley coherent phase. Our findings suggest possible
competition between intervalley coherence and superconducting orders, arising
from the intriguing correlation effects in bilayer graphene in the presence of
spin-orbit coupling.
We present and analyze a protocol for driven-dissipatively preparing and
stabilizing a manifold of quantum manybody entangled states with
symmetry-protected topological order.
Specifically, we consider the experimental platform consisting of
superconducting transmon circuits and linear microwave resonators. We perform
theoretical modeling of this platform via pulse-level simulations based on
physical features of real devices. In our protocol, transmon qutrits are mapped
onto spin-1 systems. The qutrits' sharing of nearest-neighbor dispersive
coupling to a dissipative microwave resonator enables elimination of state
population in the $S^\mathrm{total}=2$ subspace for each adjacent pair, and
thus, the stabilization of the manybody system into the Affleck, Kennedy, Lieb,
and Tasaki (AKLT) state up to the edge mode configuration. We also analyze the
performance of our protocol as the system size scales up to four qutrits, in
terms of its fidelity as well as the stabilization time. Our work shows the
capacity of driven-dissipative superconducting cQED systems to host robust and
self-corrected quantum manybody states that are topologically non-trivial.
We review recent developments in the research of nonlinear and nonequilibrium
phenomena in solids focusing on their geometrical aspects. We start with
introducing the basic concepts of geometrical phases of Bloch electrons and
Floquet theory for periodically driven systems. Then we review recent attempts
to engineer topological phases in nonequilibrium matters such as graphene,
magnets, and superconductors irradiated with circularly polarized light. We
next review a bulk photovoltaic effect of inversion broken materials focusing
on the shift current response. The shift current is described with Berry
connections and has a close relationship to the modern theory of polarization.
We further review recent extensions of the shift current to correlated electron
systems. Finally, we explain the geometric diabatic time evolution in the Zener
tunneling process and its consequences on nonreciprocal transport.
In this study, we investigate the weak localization (WL) and weak
antilocalization (WAL) effects in twisted bilayer graphene positioned on a
hexagonal boron nitride substrate. The bottom graphene layer aligns with the
hexagonal boron nitride. The top layer of the system features a Dirac cone with
a negligible gap, while the bottom layer possesses a relatively large band gap.
With a low concentration of impurities, the quantum correction to conductivity
stems from the quantum interference between two time-reversed impurity
scattering trajectories. We discover that inter-layer scattering significantly
contributes to the conductivity correction when the Fermi surface areas of the
two valleys at low energy are comparable. A double crossover from WL to WAL
andback to WL occurs at a specific range of Fermi energy, which is particularly
intriguing.
Topological insulators have been studied intensively over the last decades.
Earlier research focused on Hermitian Hamiltonians, but recently, peculiar and
interesting properties were found by introducing non-Hermiticity. In this work,
we apply a quantum geometric approach to various Hermitian and non-Hermitian
versions of the Su-Schrieffer-Heeger (SSH) model. We find that this method
allows one to correctly identify different topological phases and topological
phase transitions for all SSH models, but only when using the metric tensor
containing both left and right eigenvectors. Whereas the quantum geometry of
Hermitian systems is Riemannian, introducing non-Hermiticity leads to
pseudo-Riemannian and complex geometries, thus significantly generalizing from
the quantum geometries studied thus far. One remarkable example of this is the
mathematical agreement between topological phase transition curves and
lightlike paths in general relativity, suggesting a possibility of simulating
space-times in non-Hermitian systems. We find that the metric in non-Hermitian
phases degenerates in such a way that it effectively reduces the dimensionality
of the quantum geometry by one. This implies that within linear response
theory, one can perturb the system by a particular change of parameters while
maintaining a zero excitation rate.

Found 5 papers in prb We study the anomalous Hall effect (AHE) in tilted Weyl metals with Gaussian disorder due to the crossed $X$ and $\mathrm{Ψ}$ diagrams in this work. The importance of such diagrams to the AHE has been demonstrated recently in two-dimensional (2D) massive Dirac model and Rashba ferromagnets. It has b… We report thermal conductivity and Seebeck effect measurements on $\text{Mn}{({\text{Bi}}_{1−x}{\text{Sb}}_{x})}_{2}{\text{Te}}_{4}$ (MBST) with $x=0.26$ under applied magnetic fields below $50\phantom{\rule{0.16em}{0ex}}\mathrm{K}$. Our data shows clear indications of the electronic structure trans… Intense scrutiny over the last decade of experiments on a variety of platforms aiming to identify topological superconductivity has raised the stakes in this search. Because nontopological Andreev bound states at or near zero energy can resemble topological states, signatures beyond spectroscopy of zero-energy modes are called for. A key signature of a topological phase transition - namely, the closing and reopening of the superconducting gap - is mostly unobserved in previous experiments. Here, this phenomenon is reported in planar Josephson junction devices made from superconductor-semiconductor hybrid materials. Consistency between experiment and numerics, along with a number of other characteristic signatures, including dependence on phase, magnetic field, and chemical potential, support the conclusion that the observed gap closing and reopening, with associated appearance of a zero-bias conductance peaks upon reopening, are associated with topological transition. The development and characterization of three-dimensional topological magnetic textures has become an important topic in modern magnetism from both fundamental and technological perspectives. Here, the authors stabilize skyrmionic cocoons by engineering the properties of Pt/Co/Al based multilayers with variable Co thickness. These new textures can be observed in transmission with x-ray holography. Their coexistence with skyrmion tubes is particularly interesting as they can open new paths for three-dimensional spintronics. Historically, analytical treatments for the thermal Hall effect of many-body systems have been based around an underlying quasiparticle assumption. The authors introduce here a new purification-based tensor network method for the thermal Hall response of gapped systems, making no prior quasiparticle assumption. Motivated by reports of half-quantized thermal Hall response of Kitaev materials near field-suppressed magnetic order, the authors calculate the thermal Hall response in this parameter regime and find that it is large, but non-universal, ruling out the possibility of a revival of Ising topological order and a Majorana Hall state through this route.

High-resolution neutron and THz spectroscopies are used to study the magnetic excitation spectrum of ${\mathrm{Cs}}_{2}{\mathrm{CoBr}}_{4}$, a distorted-triangular-lattice antiferromagnet with nearly $XY$-type anisotropy. What was previously thought of as a broad excitation continuum [L. Facheris The relation between the spin current tensor, electric toroidal multipole, and chirality based on a relativistic quantum mechanical formalism, shows that the spin-derived polarization associated with the spin current tensor serves as a fundamental physical quantity that characterizes electric toroidal multipoles. First-principles model calculations predict a large tunable photovoltaic effect in electric-field-biased bilayers made of heteronodal-line systems, such as HSnN-MoS2 bilayers.
