Found 32 papers in cond-mat Helicity is a fundamental property of Dirac fermions. Yet, how it changes in
transport processes remains largely mysterious. We uncover, theoretically, the
rule of spinor state transformation and consequently universal helicity
redistribution in two cases of transport through potentials of electrostatic
and mass types, respectively. The former is dictated by Lorentz boost and its
complex counterpart in Klein tunneling regime. The latter is governed by an
abstract rotation group we identified, which reduces to SO(2) when acting on
the plane of effective mass and momentum. This endows an extra structure
foliating the Hilbert space of Dirac spinors, establishes miraculously a
unified yet latent connection between helicity, Klein tunneling, and Lorentz
boost. Our results thus deepen the understanding of relativistic quantum
transport, and may open a new window for exotic helicity-based physics and
applications in mesoscopic systems.
Relating the quantized Hall response of correlated insulators to many-body
topological invariants is a key challenge in topological quantum matter. Here,
we use Streda's formula to derive an expression for the many-body Chern number
in terms of the single-particle interacting Green's function and its derivative
with respect to a magnetic field. In this approach, we find that this many-body
topological invariant can be decomposed in terms of two contributions, $N_3[G]
+ \Delta N_3[G]$, where $N_3[G]$ is known as the Ishikawa-Matsuyama invariant,
and where the second term involves derivatives of the Green's function and the
self energy with respect to the magnetic perturbation. As a by product, the
invariant $N_3[G]$ is shown to stem from the derivative of Luttinger's theorem
with respect to the probe magnetic field. These results reveal under which
conditions the quantized Hall conductivity of correlated topological insulators
is solely dictated by the invariant $N_3[G]$, providing new insight on the
origin of fractionalization in strongly-correlated topological phases.
Motivated by remarkable properties of superfluid edge dislocations in solid
Helium-4, we discuss a broad class of quantum systems -- boundaries in phase
separated lattice states, magnetic domain walls, and ensembles of Luttinger
liquids -- that can be classified as Transverse Quantum Fluids (TQF). After
introducing the general idea of TQF, we focus on a coupled array of Luttinger
liquids forming an incoherent TQF. This state is a long-range ordered
quasi-one-dimensional superfluid, topologically protected against quantum phase
slips by tight-binding of instanton dipoles, that has no coherent
quasi-particle excitations at low energies. Incoherent TQF is a striking
example of the irrelevance of the Landau quasiparticle criterion for
superfluidity in systems that lack Galilean invariance. We detail its
phenomenology, to motivate a number of experimental studies in condensed matter
and cold atomic systems.
The simulation of quantum Hall physics with rotating quantum gases is
witnessing a revival due to recent experimental advances that enabled the
observation of a Bose-Einstein condensate entirely contained in its lowest
kinetic energy state, i.e. the lowest Landau level. We theoretically describe
this experimental result, and show that it can be interpreted as a squeezing of
the geometric degree of freedom of the problem, the guiding center metric. This
"geometric squeezing" offers an unprecedented experimental control over the
quantum geometry in Landau-level analogues, and at the same time opens a
realistic path towards achieving correlated quantum phases akin to quantum Hall
states with neutral atoms.
In recent years, the 'kirigami' technique has gained significant attention
for creating meta-structures and meta-materials with exceptional
characteristics, such as unprecedented stretchability. These properties, not
typically inherent in the original materials or structures, present new
opportunities for applications in stretchable electronics and photovoltaics.
However, despite its scientific and practical significance, the application of
kirigami patterning on a monolayer of tungsten disulfide (WS2), a van der Waals
material with exceptional mechanical, electronic, and optical properties, has
remained unexplored. This study utilizes molecular dynamics (MD) simulations to
investigate the mechanical properties of monolayer WS2 with rectangular
kirigami cuts. We find that, under tensile loading, the WS2 based kirigami
structure exhibits a notable increase in tensile strain and a decrease in
strength, thus demonstrating the effectiveness of the kirigami cutting
technique in enhancing the stretchability of monolayer WS2. Additionally,
increasing the overlap ratio enhances the stretchability of the structure,
allowing for tailored high strength or high strain requirements. Furthermore,
our observations reveal that increasing the density of cuts and reducing the
length-to-width ratio of the kirigami nanosheet further improve the fracture
strain, thereby enhancing the overall stretchability of the proposed kirigami
patterned structure of WS2.
We demonstrate the utility of machine learning algorithms for the design of
Oscillatory Neural Networks (ONNs). After constructing a circuit model of the
oscillators in a machine-learning-enabled simulator and performing
Backpropagation through time (BPTT) for determining the coupling resistances
between the ring oscillators, we show the design of associative memories and
multi-layered ONN classifiers. The machine-learning-designed ONNs show superior
performance compared to other design methods (such as Hebbian learning) and
they also enable significant simplifications in the circuit topology. We
demonstrate the design of multi-layered ONNs that show superior performance
compared to single-layer ones. We argue Machine learning can unlock the true
computing potential of ONNs hardware.
Designer heterostructures, where the desired physics emerges from the
controlled interactions between different components, represent one of the most
powerful strategies to realize unconventional electronic states. This approach
has been particularly fruitful in combining magnetism and superconductivity to
create exotic superconducting states. In this work, we use a heterostructure
platform combining supramolecular metal complexes (SMCs) with a quasi-2D van
der Waals (vdW) superconductor NbSe$_2$. Our scanning tunneling microscopy
(STM) measurements demonstrate the emergence of Yu-Shiba-Rusinov (YSR) bands
arising from the interaction between the SMC magnetism and the NbSe$_2$
superconductivity. Using X-ray absorption spectroscopy (XAS) and X-ray magnetic
circular dichroism (XMCD) measurements, we show the presence of
antiferromagnetic coupling between the SMC units. These result in the emergence
of an unconventional $3\times3$ reconstruction in the magnetic ground state
that is directly reflected in real space modulation of the YSR bands. The
combination of flexible molecular building blocks, frustrated magnetic
textures, and superconductivity in heterostructures establishes a fertile
starting point to fabricating tunable quantum materials, including
unconventional superconductors and quantum spin liquids.
The magic-angle twisted bilayer graphene (MATBLG) has been demonstrated to
exhibit exotic physical properties due to the special flat bands. However,
exploiting the engineering of such properties by external fields is still in it
infancy. Here we show that MATBLG under an external magnetic field presents a
distinctive magnetoplasmon dispersion, which can be significantly modified by
transferred momentum and charge doping. Along a wide range of transferred
momentum, there exist special pronounced single magnetoplasmon and horizontal
single-particle excitation modes near charge neutrality. We provide an
insightful discussion of such unique features based on the electronic
excitation of Landau levels quantized from the flat bands and Landau damping.
Additionally, charge doping leads to peculiar multiple strong-weight
magnetoplasmons. These characteristics make MATBLG a favorable candidate for
plasmonic devices and technology applications.
We propose an experimental approach for determining thermodynamic properties
of ultracold atomic gases with short-range interactions. As a test case, we
focus on the one-dimensional (1D) Bose gas described by the integrable
Lieb-Liniger model. The proposed approach relies on deducing the Helmholtz or
Landau free energy directly from measurements of local atom-atom correlations
by utilising the inversion of a finite-temperature version of the
Hellmann-Feynman theorem. We demonstrate this approach theoretically by
deriving approximate analytic expressions for the free energies in specific
asymptotic regimes of the 1D Bose gas and find excellent agreement with the
exact results based on the thermodynamic Bethe ansatz available for this
integrable model.
Humans are constantly exposed to sequences of events in the environment.
Those sequences frequently evince statistical regularities, such as the
probabilities with which one event transitions to another. Collectively,
inter-event transition probabilities can be modeled as a graph or network. Many
real-world networks are organized hierarchically and understanding how humans
learn these networks is an ongoing aim of current investigations. While much is
known about how humans learn basic transition graph topology, whether and to
what degree humans can learn hierarchical structures in such graphs remains
unknown. We investigate how humans learn hierarchical graphs of the
Sierpi\'nski family using computer simulations and behavioral laboratory
experiments. We probe the mental estimates of transition probabilities via the
surprisal effect: a phenomenon in which humans react more slowly to less
expected transitions, such as those between communities or modules in the
network. Using mean-field predictions and numerical simulations, we show that
surprisal effects are stronger for finer-level than coarser-level hierarchical
transitions. Surprisal effects at coarser levels of the hierarchy are difficult
to detect for limited learning times or in small samples. Using a serial
response experiment with human participants (n=$100$), we replicate our
predictions by detecting a surprisal effect at the finer-level of the hierarchy
but not at the coarser-level of the hierarchy. To further explain our findings,
we evaluate the presence of a trade-off in learning, whereby humans who learned
the finer-level of the hierarchy better tended to learn the coarser-level
worse, and vice versa. Our study elucidates the processes by which humans learn
hierarchical sequential events. Our work charts a road map for future
investigation of the neural underpinnings and behavioral manifestations of
graph learning.
We investigate the dynamical relaxation behavior of the two-point correlation
in extended XY models with a gapless phase after quenches from various initial
states. Specifically, we study the XY chain with gapless phase induced by the
additional interactions: Dzyaloshinskii-Moriya interaction and XZY-YZX type of
three-site interaction. When quenching from the gapped phase, we observe that
the additional interactions have no effect on the relaxation behavior. The
relaxation behavior is $\delta C_{mn}(t)\sim t^{-3/2}$ and $\sim t^{-1/2}$ for
the quench to the commensurate phase and the incommensurate phase,
respectively. However, when quenching from the gapless phase, we demonstrate
that the scaling behavior of $\delta C_{mn}(t)$ is changed to $\sim t^{-1}$ for
the quench to the commensurate phase, and the decay of $\delta C_{mn}(t)$
follows $\sim t^{-1}$ or $\sim t^{-1/2}$ for the quench to the incommensurate
phase depending on the parameters of pre-quench Hamiltonian. We also establish
the dynamical phase diagrams based on the dynamical relaxation behavior of
$\delta C_{mn}(t)$ in the extended XY models.
Why do experiments only exhibit one magic angle if the chiral limit of the
Bistritzer-MacDonald Hamiltonian suggest a plethora of them? - In this article,
we investigate the remarkable stability of the first magic angle in contrast to
higher (smaller) magic angles. More precisely, we examine the influence of
disorder on magic angles and the Bistritzer-MacDonald Hamiltonian. We establish
the existence of a mobility edge near the energy of the flat band for small
disorder. We also show that the mobility edges persist even when all global
Chern numbers become zero, leveraging the $C_{2z}T$ symmetry of the system to
demonstrate non-trivial sublattice transport. This effect is robust even beyond
the chiral limit and in the vicinity of perfect magic angles, as is expected
from experiments.
Recently, the quantum spin-Hall edge channels of two-dimensional colloidal
nanocrystals of the topological insulator Bi$_2$Se$_3$ were observed directly.
Motivated by this development, we reconsider the four-band effective model
which has been traditionally employed in the past to describe thin nanosheets
of this material. Derived from a three-dimensional $\boldsymbol{k}
\boldsymbol{\cdot} \boldsymbol{p}$ model, it physically describes the top and
bottom electronic surface states that become gapped due to the material's small
thickness. However, we find that the four-band model for the surface states
alone, as derived directly from the three-dimensional theory, is inadequate for
the description of thin films of a few quintuple layers and even yields an
incorrect topological invariant within a significant range of thicknesses. To
address this limitation we propose an eight-band model which, in addition to
the surface states, also incorporates the set of bulk bands closest to the
Fermi level. We find that the eight-band model not only captures most of the
experimental observations, but also agrees with previous first-principles
calculations of the $\mathbb{Z}_{2}$ invariant in thin films of varying
thickness. Moreover, we demonstrate that the topological properties of thin
Bi$_2$Se$_3$ nanosheets emerge as a result of an intricate interplay between
the surface and bulk states, which in fact results in nontrivial Chern numbers
for the latter.
A novel spin texture formed by Cooper pair spins is found theoretically with
a phase string attached by half-quantized vortices at both ends in a unit cell
and characterized by its topologically rich vortex structure in a spin-triplet
pairing. It is stable at an intermediate field region sandwiched by two
conventional singular vortex phases below and above it. The d-vector direction
of this spin texture is tilted from the principal crystal axes, whose spin
susceptibility is neither the normal Pauli one \c{hi}N nor zero, describing
microscopically the process of the d-vector rotation phenomena observed
recently in UTe2. We compare the spin texture and singular vortex state in
relation to the quasi-particle structure with Majorana zero modes for STM, the
nuclear spin resonance spectral line width for NMR and {\mu}SR, and the vortex
form factors for SANS to facilitate the identification of the pairing symmetry
in UTe2.
Irradiation of solid surfaces with high intensity, ultrashort laser pulses
triggers a variety of secondary processes that can lead to the formation of
transient and permanent structures over large range of length scales from mm
down to the nano-range. One of the most prominent examples are LIPSS - Laser
Induced Periodic Surface Structures. While LIPSS have been a scientific
evergreen for of almost 60 years, experimental methods that combine ultrafast
temporal with the required nm spatial resolution have become available only
recently with the advent of short pulse, short wavelength free electron lasers.
Here we discuss the current status and future perspectives in this field by
exploiting the unique possibilities of these 4th-generation light sources to
address by time-domain experimental techniques the fundamental LIPSS-question,
namely why and how laser-irradiation can initiate the transition of a "chaotic"
(rough) surface from an aperiodic into a periodic structure.
Facing with grave climate change and enormous energy demand, catalyzer gets
more and more important due to its significant effect on reducing fossil fuels
consumption. Hydrogen evolution reaction (HER) and oxygen evolution reaction
(OER) by water splitting are feasible ways to produce clean sustainable energy.
Here we systematically explored atomic structures and related STM images of Se
defects in PtSe2. The equilibrium fractions of vacancies under variable
conditions were detailly predicted. Besides, we found the vacancies are highly
kinetic stable, without recovering or aggregation. The Se vacancies in PtSe2
can dramatically enhance the HER performance, comparing with, even better than
Pt(111). Beyond, we firstly revealed that PtSe2 monolayer with Se vacancies is
also a good OER catalyst. The excellent bipolar catalysis of Se vacancies were
further confirmed by experimental measurements. We produced defective PtSe2 by
direct selenization of Pt foil at 773 K using a CVD process. Then we observed
the HER and OER performance of defective PtSe2 is much highly efficient than Pt
foils by a series of measurements. Our work with compelling theoretical and
experimental studies indicates PtSe2 with Se defects is an ideal bipolar
candidate for HER and OER.
We describe the chiral Kondo chain model based on the symplectic Kondo effect
and demonstrate that it has a quantum critical ground state populated by
non-Abelian anyons. We show that the fusion channel of two arbitrary anyons can
be detected by locally coupling the two anyons to an extra single channel of
chiral current and measuring the corresponding conductance at finite frequency.
Based on such measurements, we propose that the chiral Kondo chain model with
symplectic symmetry can be used for implementation of measurement-only
topological quantum computations, and it possesses a number of distinct
features favorable for such applications. The sources and effects of errors in
the proposed system are analyzed, and possible material realizations are
discussed.
We examine topological phases and symmetry-protected electronic edge states
in the context of a Rydberg composite: a Rydberg atom interfaced with a
structured arrangement of ground-state atoms. The electronic Hamiltonian of
such a composite possesses a direct mapping to a tight-binding Hamiltonian,
which enables the realization and study of a variety of systems with
non-trivial topology by tuning the arrangement of ground-state atoms and the
excitation of the Rydberg atom. The Rydberg electron moves in a combined
potential including the long-ranged Coulomb interaction with the Rydberg core
and short-ranged interactions with each neutral atom; the effective
interactions between sites are determined by this combination. We first confirm
the existence of topologically-protected edge states in a Rydberg composite by
mapping it to the paradigmatic Su-Schrieffer-Heeger dimer model. Following
that, we study more complicated systems with trimer unit cells which can be
easily simulated with a Rydberg composite.
We theoretically investigate influences of electronic circuit delay, noise
and temperature on write-error-rate (WER) in voltage-controlled magnetization
switching operation of a magnetic-topological-insulator-based (MTI) device by
means of the micromagnetic simulation. This device realizes magnetization
switching via spin-orbit torque(SOT) and voltage-controlled magnetic anisotropy
(VCMA) which originate from 2D-Dirac electronic structure. We reveal that the
device operation is extremely robust against circuit delay and signal-to-noise
ratio. We demonstrate that the WER on the order of approximately $10^{-4}$ or
below is achieved around room temperature due to steep change in VCMA. Also, we
show that the larger SOT improves thermal stability factor. This study provides
a next perspective for developing voltage-driven spintronic devices with
ultra-low power consumption.
Ultraflat bands have already been detected in twisted bilayer graphene (TBG)
and twisted bilayer transition metal dichalcogenides (tb-TMDs), which provide a
platform to investigate strong correlations. In this paper, the electronic
properties of twisted trilayer molybdenum disulfide (TTM) are investigated via
an accurate tight-banding Hamiltonian. We find that the highest valence bands
are derived from $\Gamma$-point of the constituent monolayer, exhibiting a
graphene-like dispersion or becoming isolated flat bands. The lattice
relaxation, local deformation, and electric field can significantly tune the
electronic structures of TTM with different starting stacking arrangements.
After introducing the spin-orbital coupling (SOC) effect, we find a
spin-valley-layer locking effect at the minimum of conduction band at K- and
K$^\prime$-point of the Brillouin zone, which may provide a platform to study
optical properties and magnetoelectric effects.
Spin qubits have attracted tremendous attention in the effort of building
quantum computers over the years. Natural atomic scale candidates are group-V
dopants in silicon, not only showing ultra-long lifetimes but also being
compatible with current semiconductor technology. Nevertheless, bulk dopants
are difficult to move with atomic precision, impeding the realization of
desired structures for quantum computing. A solution is to place the atom on
the surface which opens possibilities for atom level manipulations using
scanning tunneling microscopy (STM). For this purpose, bismuth appears to be a
good candidate. Here, we use ab-initio methods to study theoretically the
adsorption of bismuth atoms on the Si(001) surface and investigate the
adsorption sites and the transitions between them. We demonstrate the complex
influence of the dimer row surface reconstruction on the energy landscape seen
by a bismuth monomer and a dimer on the surface, and find anisotropic
transition paths for movement on the surface. From a deposition simulation we
obtain the expected occupation of adsorption sites. Our work lays the
foundation for further application of bismuth atoms as qubits on silicon
surfaces.
The quest to identify and observe Majorana fermions in physics and
condensed-matter systems remains an important challenge. Here, we introduce a
qubit (spin-1/2) from the occurrence of two delocalized zero-energy Majorana
fermions in a model of two spins-1/2 on the Bloch sphere within the fractional
one-half topological state. We address specific protocols in time with
circularly polarized light and the protection of this spin-1/2 state related to
quantum information protocols. We also show how disorder can play a positive
and important role allowing singlet-triplet transitions and resulting in an
additional elongated region for the fractional phase, demonstrating the
potential of this platform related to applications in topologically protected
quantum information.
It is show that one can derive a novel BPS bound for the gauged
Non-Linear-Sigma-Model (NLSM) Maxwell theory in (3+1) dimensions which can
actually be saturated. Such novel bound is constructed using Hamilton-Jacobi
equation from classical mechanics. The configurations saturating the bound
represent Hadronic layers possessing both Baryonic charge and magnetic flux.
However, unlike what happens in the more common situations, the topological
charge which appears naturally in the BPS bound is a non-linear function of the
Baryonic charge. This BPS bound can be saturated when the surface area of the
layer is quantized. The far-reaching implications of these results are
discussed. In particular, we determine the exact relation between the magnetic
flux and the Baryonic charge as well as the critical value of the Baryonic
chemical potential beyond which these configurations become thermodynamically
unstable.
Using the Landau-Ginzburg-Devonshire approach and effective media models, we
calculated the spontaneous polarization, dielectric, pyroelectric, and
electrocaloric properties of BaTiO$_3$ core-shell nanoparticles. We predict
that the synergy of size effects and Vegard stresses can significantly improve
the electrocaloric cooling (2- 7 times) of the BaTiO$_3$ nanoparticles with
diameters (10-100) nm stretched by (1-3)% in comparison with a bulk BaTiO$_3$.
To compare with the proposed and other known models, we measured the
capacitance-voltage and current-voltage characteristics of the dense
nanocomposites consisting of (28 -35) vol.% of the BaTiO$_3$ nanoparticles
incorporated in the poly-vinyl-butyral and ethyl-cellulose polymers covered by
Ag electrodes. We determined experimentally the effective dielectric
permittivity and losses of the dense composites at room temperature. According
to our analysis, to reach the maximal electrocaloric response of the core-shell
ferroelectric nanoparticles incorporated in different polymers, the dense
composites should be prepared with the nanoparticles volume ratio of more than
25 % and fillers with low heat mass and conductance, such as Ag nanoparticles,
which facilitate the heat transfer from the ferroelectric nanoparticles to the
polymer matrix. In general, the core-shell ferroelectric nanoparticles
spontaneously stressed by elastic defects, such as oxygen vacancies or any
other elastic dipoles, which create a strong chemical pressure, are relevant
fillers for electrocaloric nanocomposites suitable for advanced applications as
nano-coolers.
The study of geometrically frustrated many-body quantum systems is of central
importance to uncover novel quantum mechanical effects. We design a scheme
where ultracold bosons trapped in a one-dimensional state-dependent optical
lattice are modeled by a frustrated Bose-Hubbard Hamiltonian. A derivation of
the Hamiltonian parameters based on Cesium atoms, further show large tunability
of contact and nearest-neighbour interactions. For pure contact repulsion, we
discover the presence of two phases peculiar to frustrated quantum magnets: the
bond-order-wave insulator with broken inversion symmetry and a chiral
superfluid. When the nearest-neighbour repulsion becomes sizeable, a further
density-wave insulator with broken translational symmetry can appear. We show
that the phase transition between the two spontaneously-symmetry-broken phases
is continuous, thus representing a one-dimensional deconfined quantum critical
point not captured by the Landau-Ginzburg-Wilson symmetry-breaking paradigm.
Our results provide a solid ground to unveil the novel quantum physics induced
by the interplay of non-local interactions, geometrical frustration, and
quantum fluctuations.
Colloidal probe Atomic Force Microscopy allows to explore sliding states of
vanishing friction, i.e. superlubricity, in mesoscopic graphite contacts.
Superlubricity is known to appear upon formation of a triboinduced transfer
layer, originated by material transfer of graphene flakes from the graphitic
substrate to the colloidal probe. Previous studies suggest that friction
vanishes due to crystalline incommensurability at the newly formed interface.
However this picture still lacks several details, such as the roles of the
tribolayer roughness and of loading conditions. Hereafter we gain deeper
insight into the tribological response of micrometric silica beads sliding on
graphite under ambient conditions. We show that the tribotransferred flakes
behave as lubricious nanoasperities with a twofold role. First, they decrease
the silica-graphite true contact area, in fact causing a breakdown of adhesion
and friction by one order of magnitude. Second, they govern mechanical
dissipation through the specific energy landscape experienced by the
topographically-highest triboinduced nanoasperity. Remarkably, such contact
junctions can undergo a load-driven atomic-scale transition from continuous
superlubric sliding to dissipative stick-slip, that agrees with the
single-asperity Prandtl-Tomlinson model. Superlubricity in mesoscopic
silica-graphite junctions may therefore arise from the load-controlled
competition between interfacial crystalline incommensurability and contact
pinning effects at one dominant nanoasperity.
Physical mechanisms of structural transformations in deposited metallic
clusters exposed to an electron beam of a transmission electron microscope
(TEM) are studied theoretically and computationally. Recent TEM experiments
with size-selected Au$_{923}$ clusters softly deposited on a carbon substrate
showed that the clusters undergo structural transformations from icosahedron to
decahedron and face-center cubic (fcc) structures upon exposure to a 200-keV
electron beam. In this paper, we demonstrate that the relaxation of collective
electronic (plasmon) excitations formed in deposited metal clusters can induce
the experimentally observed structural transformations. Such excitations in the
clusters are formed mainly due to the interaction with low-energy secondary
electrons emitted from a substrate. The characteristic occurrence times for
plasmon-induced energy relaxation events are several orders of magnitude
shorter than those for the momentum transfer events by energetic primary
electrons to atoms of the cluster. The theoretical analysis is complemented by
molecular dynamics simulations, which show that an icosahedral Au$_{923}$
cluster softly deposited on graphite is transformed into an fcc-like structure
due to the vibrational excitation of the cluster.
Exceptional points (EPs) of non-Hermitian (NH) systems have recently
attracted increasing attention due to their rich phenomenology and intriguing
applications. Compared to the predominantly studied second-order EPs,
higher-order EPs have been assumed to play a much less prominent role because
they generically require the tuning of more parameters. Here we experimentally
simulate two-dimensional topological NH band structures using single-photon
interferometry, and observe topologically stable third-order EPs obtained by
tuning only two real parameters in the presence of symmetry. In particular, we
explore how different symmetries stabilize qualitatively different third-order
EPs: the parity-time symmetry leads to a generic cube-root dispersion, while a
generalized chiral symmetry implies a square-root dispersion coexisting with a
flat band. Additionally, we simulate fourfold degeneracies, composed of the
non-defective twofold degeneracies and second-order EPs. Our work reveals the
abundant and conceptually richer higher-order EPs protected by symmetries and
offers a versatile platform for further research on topological NH systems.
Topological quantum computation by way of braiding of Majorana fermions is
not universal quantum computation. There are several attempts to make universal
quantum computation by introducing some additional quantum gates or quantum
states. However, there is an embedding problem that $M$-qubit gates cannot be
embedded straightforwardly in $N$ qubits for $N>M$. This problem is inherent to
the Majorana system, where logical qubits are different from physical qubits
because braiding operations preserve the fermion parity. By introducing
$2N$-body interactions of Majorana fermions, topological-nontopological hybrid
universal quantum computation is shown to be possible. Especially, we make a
systematic construction of the C$^{n}$Z gate, C$^{n}$NOT gate and the
C$^{n}$SWAP gate.
Green's function zeros, which can emerge only if correlation is strong, have
been for long overlooked and believed to be devoid of any physical meaning,
unlike Green's function poles. Here, we prove that Green's function zeros
instead contribute on the same footing as poles to determine the topological
character of an insulator. The key to the proof, worked out explicitly in 2D
but easily extendable in 3D, is to express the topological invariant in terms
of a quasiparticle thermal Green's function matrix $G_*(i\epsilon,\mathbf{k})=
1/\big(i\epsilon-H_*(\epsilon,\mathbf{k})\big)$, with hermitian
$H_*(\epsilon,\mathbf{k})$, by filtering out the positive definite
quasiparticle residue. In that way, the topological invariant is easily found
to reduce to the TKNN formula for quasiparticles described by the
non-interacting Hamiltonian $H_*(0,\mathbf{k})$. Since the poles of the
quasiparticle Green's function $G_*(\epsilon,\mathbf{k})$ on the real frequency
axis correspond to poles and zeros of the physical-particle Green's function
$G(\epsilon,\mathbf{k})$, both of them equally determine the topological
character of an insulator.
We present a machine-learning model based on normalizing flows that is
trained to sample from the isobaric-isothermal ensemble. In our approach, we
approximate the joint distribution of a fully-flexible triclinic simulation box
and particle coordinates to achieve a desired internal pressure. This novel
extension of flow-based sampling to the isobaric-isothermal ensemble yields
direct estimates of Gibbs free energies. We test our NPT-flow on monatomic
water in the cubic and hexagonal ice phases and find excellent agreement of
Gibbs free energies and other observables compared with established baselines.
We study the non equilibrium Casimir-Lifshitz force between graphene-based
parallel structures held at different temperatures and in presence of an
external thermal bath at a third temperature. The graphene conductivity, which
is itself a function of temperature, as well as of chemical potential, allows
us to tune in situ the Casimir-Lifshitz force. We explore different non
equilibrium configurations while considering different values of the graphene
chemical potential. Particularly interesting cases are investigated, where the
force can change sign going from attractive to repulsive or where the force
becomes non monotonic with respect to chemical potential variations, contrary
to the behaviour under thermal equilibrium.

Found 6 papers in prb Structure factors obtained from diffraction experiments are one of the most important quantities for characterizing the electronic and structural properties of materials. Methods for calculating this quantity from plane-wave density functional theory (DFT) codes are typically prohibitively expensive… I propose monoradical nanographenes without ${C}_{3}$ symmetry as building blocks to design two-dimensional carbon crystals.

Based on first-principles calculations, here we propose a 2D IMC class assembled from diatomic molecules whose building blocks are derived from a single el… We show that the rainbow state, which has volume-law entanglement entropy for most choices of bipartitions, can be embedded in a many-body localized spectrum. For a broad range of disorder strengths in the resulting model, we numerically find a narrow window of highly entangled states in the spectru… Topological insulators in two-dimensional systems are well-understood within the context of free-fermion systems. Nevertheless, comprehending their strongly interacting counterparts presents a significant challenge. Here, the authors developed an innovative lattice model based on $U(1{)}_{f}$ fermionic charge decorations. The model furnishes a rigorous mathematical framework for delving into fermionic symmetry-protected topological phases that conserve $U(1{)}_{f}$ charge, among other types of symmetries. Notably, this research expands the existing theoretical landscape by presenting an exactly solvable Hamiltonian with a finite local Hilbert space and a sophisticated classification scheme for continuous symmetries. We elucidate the properties of a robust transverse polarization mode in heterostructures of transition metal dichalcogenides. This
