Found 22 papers in cond-mat The black-hole laser (BHL) effect is the self-amplification of Hawking
radiation in the presence of a pair of horizons which act as a resonant cavity.
Its clear observation still remains a major challenge in the analogue gravity
field. In a flowing atomic condensate, the BHL effect arises in a finite
supersonic region, where Bogoliubov-Cherenkov-Landau (BCL) radiation is
resonantly excited by any static perturbation. Thus, any experimental attempt
to produce a BHL will deal with the presence of a BCL background, as already
observed in experiments. Here, we perform a theoretical study of the BHL-BCL
crossover using an idealized model where both phenomena can be unambiguously
isolated. By drawing an analogy with an unstable pendulum, we distinguish three
main regimes according to the interplay between quantum fluctuations and
classical stimulation: quantum BHL, classical BHL, and BCL. Based on quite
general scaling arguments, the nonlinear amplification of quantum fluctuations
until saturation is identified as the most robust trait of a quantum BHL. A
classical BHL behaves instead as a linear quantum amplifier, where the output
is proportional to the input. Finally, the BCL regime also acts as a linear
quantum amplifier, but its gain is exponentially smaller as compared to a
classical BHL. The results of this work not only are of interest for analogue
gravity, where they help to distinguish unambiguously each phenomenon and to
design experimental schemes for a clear observation of the BHL effect, but they
also open the prospect of finding applications of analogue concepts in quantum
technologies.
Quantum loop models are well studied objects in the context of lattice gauge
theories and topological quantum computing. They usually carry long range
entanglement that is captured by the topological entanglement entropy. I
consider generalization of the toric code model to bicolor loop models and show
that the long range entanglement can be reflected in three different ways: a
topologically invariant constant, a sub-leading logarithmic correction to the
area law, or a modified bond dimension for the area-law term. The Hamiltonians
are not exactly solvable for the whole spectra, but admit a tower of area-law
exact excited states corresponding to the frustration free superposition of
loop configurations with arbitrary pairs of localized vertex defects. The
continuity of color along loops imposes kinetic constraints on the model and
results in Hilbert space fragmentation, unless plaquette operators involving
two neighboring faces are introduced to the Hamiltonian.
The chemical fueling of transient states (CFTS) is a powerful process to
control the nonequilibrium structuring and the homeostatic function of adaptive
soft matter systems. Here, we introduce a mean-field model of CFTS based on the
activation of metastable equilibrium states in a tilted Landau bistable energy
landscape along a coarse-grained reaction coordinate (or order parameter)
triggered by a nonmonotonic two-step chemical fueling reaction. Evaluation of
the model in the quasi-static (QS) limit - valid for fast system relaxation -
allows us to extract useful analytical laws for the critical activation
concentration and duration of the transient states in dependence of physical
parameters, such as rate constants, fuel concentrations, and the system's
distance to its equilibrium transition point. We apply our model in the QS
limit to recent experiments of CFTS of collapsing responsive microgels and find
a very good performance with only a few global and physically interpretable
fitting parameters, which can be employed for programmable material design.
Moreover, our model framework also allows a thermodynamic analysis of the
energy and performed work in the system. Finally, we go beyond the QS limit,
where the system's response is slow and retarded versus the chemical reaction,
using an overdamped Smoluchowski approach. The latter demonstrates how internal
system time scales can be used to tune the time-dependent behavior and
programmed delay of the transient states in full nonequilibrium.
Epitaxial growth has become a promising route to achieve highly crystalline
continuous two-dimensional layers. However, high-quality layer production with
expected electrical properties is still challenging due to the defects induced
by the coalescence between imperfectly aligned domains. In order to control
their intrinsic properties at the device scale, the synthesized materials
should be described as a patchwork of coalesced domains. Here, we report
multi-scale and multistructural analysis on highly oriented epitaxial WS$_2$
and WSe$_2$ monolayers using scanning transmission electron microscopy (STEM)
techniques. Characteristic domain junctions are first identified and classified
based on the detailed atomic structure analysis using aberration corrected STEM
imaging. Mapping orientation, polar direction and phase at the micrometer scale
using four-dimensional STEM enabled to access the density and the distribution
of the specific domain junctions. Our results validate a readily applicable
process for the study of highly oriented epitaxial transition metal
dichalcogenides, providing an overview of synthesized materials from large
scale down to atomic scale with multiple structural information.
Strong long-range interactions up to third nearest neighbors may induce a
topological phase transition in one-dimensional chains. Unlike the
Su-Schrieffer-Heeger model, this transition from trivial to topological phase
occurs with the emergence of a pseudospin valley structure and a twofold
nontrivial topological phase. Within a tight-binding approach, these
topological phases are analyzed in detail and it is shown that the low-energy
excitations follow a modified Dirac equation. An experimental realization in a
one-dimensional elastic chain, where it is feasible to tune directly the
third-nearest-neighbor interaction strength, is proposed.
Vortex phenomena are ubiquitous in nature, from vortices of quantum particles
and living cells [1-7], to whirlpools, tornados, and spiral galaxies. Yet,
effective control of vortex transport from one place to another at any scale
has thus far remained a challenging goal. Here, by use of topological
disclination [8,9], we demonstrate a scheme to confine and guide vortices of
arbitrary high-order charges10,11. Such guidance demands a double topological
protection: a nontrivial winding in momentum space due to chiral symmetry
[12,13] and a nontrivial winding in real space arising from collective complex
coupling between vortex modes. We unveil a vorticity-coordinated rotational
symmetry, which sets up a universal relation between the topological charge of
a guided vortex and the order of rotational symmetry of the disclination
structure. As an example, we construct a C3-symmetry photonic lattice with a
single-core disclination, thereby achieving robust transport of an optical
vortex with preserved orbital angular momentum (OAM) that corresponds solely to
one excited vortex mode pinned at zero energy. Our work reveals a fundamental
interplay of vorticity, disclination and higher-order topological phases14-16,
applicable broadly to different fields, promising in particular for OAM-based
photonic applications that require vortex guides, fibers [17,18] and lasers
[19].
Topological insulators (TI) can apply highly efficient spin-orbit torque
(SOT) and manipulate the magnetization with their unique topological surface
states, and their magnetic counterparts, magnetic topological insulators (MTI)
offer magnetization without shunting and are one of the highest in SOT
efficiency. Here, we demonstrate efficient SOT switching of a hard MTI, V-doped
(Bi,Sb)2Te3 (VBST) with a large coercive field that can prevent the influence
of an external magnetic field and a small magnetization to minimize stray
field. A giant switched anomalous Hall resistance of 9.2 $k\Omega$ is realized,
among the largest of all SOT systems. The SOT switching current density can be
reduced to $2.8\times10^5 A/cm^2$, and the switching ratio can be enhanced to
60%. Moreover, as the Fermi level is moved away from the Dirac point by both
gate and composition tuning, VBST exhibits a transition from
edge-state-mediated to surface-state-mediated transport, thus enhancing the SOT
effective field to $1.56\pm 0.12 T/ (10^6 A/cm^2)$ and the spin Hall angle to
$23.2\pm 1.8$ at 5 K. The findings establish VBST as an extraordinary candidate
for energy-efficient magnetic memory devices.
We examine possible ordered states of AA stacked bilayer graphene arising due
to electron-electron coupling. We show that under certain assumptions the
Hamiltonian of the system possesses an SU(4) symmetry. The multicomponent order
parameter is described by a $4\times4$ matrix $\hat{Q}$, for which a mean-field
self-consistency equation is derived. This equation allows Hermitian and
non-Hermitian solutions. Hermitian solutions can be grouped into three
topologically-distinct classes. First class corresponds to the charge density
wave. Second class includes spin density wave, valley density wave, and
spin-valley density wave. An ordered state in the third class is a combination
of all the aforementioned density-wave types. For anti-Hermitian $\hat{Q}$ the
ordered state is characterized by a spontaneous inter-layer loop currents
flowing in the bilayer. Depending on the topological class of the solution
these currents can carry charge, spin, valley, and spin-valley quanta. We also
discuss the special case when matrix $\hat{Q}$ is not Hermitian and not
anti-Hermitian. Utility and weak points of the proposed SU(4)-based
classification scheme of the ordered states are analyzed.
The thermodynamics of low-dimensional systems departs significantly from
phenomenologically deducted macroscopic laws. Particular examples, not yet
fully understood, are provided by the breakdown of Fourier's law and the
ballistic transport of heat. Low-dimensional trapped ion systems provide an
experimentally accessible and well-controlled platform for the study of these
problems. In our work, we study the transport of thermal energy in
low-dimensional trapped ion crystals, focusing in particular on the influence
of the Aubry-like transition that occurs when a topological defect is present
in the crystal. We show that the transition significantly hinders efficient
heat transport, being responsible for the rise of a marked temperature gradient
in the non-equilibrium steady state. Further analysis reveals the importance of
the motional eigenfrequencies of the crystal.
We theoretically calculate the dynamic structure factor of two-dimensional
Rashba-type spinorbit coupled (SOC) Fermi superfluid with random phase
approximation, and analyse the main characters of dynamical excitation sh own
by both density and spin dynamic structure factor during a continuous phase
transition between Bardeen-Cooper-Schrieffer superfluid and topological
superfluid. Generally we find three different excitations, including collective
phonon excitation, two-atom molecular and atomic excitations, and pair-breaking
excitations due to two-branch structure of quasi-particle spectrum. It should
be emphasized that collective phonon excitation is overlapped with a gapless DD
type pair-breaking excitation at the critical Zeeman field hc, and is imparted
a finite width to phonon peak when transferred momentum q is around Fermi
vector kF. At a much larger transferred momentum (q = 4kF ), the pair-breaking
excitation happens earlier than two-atom molecular excitation, which is
different from the conventional Fermi superfluid without SOC effect.
In conventional metal superconductors such as aluminum, the large number of
weakly bounded Cooper pairs become phase coherent as soon as they start to
form. The cuprate high critical temperature ($T_c$) superconductors, in
contrast, belong to a distinctively different category. To account for the high
$T_c$, the attractive pairing interaction is expected to be strong and the
coherence length is short. Being doped Mott insulators, the cuprates are known
to have low superfluid density, thus are susceptible to phase fluctuations. It
has been proposed that pairing and phase coherence may occur separately in
cuprates, and $T_c$ corresponds to the phase coherence temperature controlled
by the superfluid density. To elucidate the microscopic processes of pairing
and phase ordering in cuprates, here we use scanning tunneling microscopy to
image the evolution of electronic states in underdoped $\rm
Bi_2La_xSr_{2-x}CuO_{6+{\delta}}$. Even in the insulating sample, we observe a
smooth crossover from the Mott insulator to superconductor-type spectra on
small islands with chequerboard order and emerging quasiparticle interference
patterns following the octet model. Each chequerboard plaquette contains
approximately two holes, and exhibits a stripy internal structure that has
strong influence on the superconducting features. Across the insulator to
superconductor boundary, the local spectra remain qualitatively the same while
the quasiparticle interferences become long-ranged. These results suggest that
the chequerboard plaquette with internal stripes plays a crucial role on local
pairing in cuprates, and the global phase coherence is established once its
spatial occupation exceeds a threshold.
Cooperative dynamics are central to our understanding of many phenomena in
living and complex systems, including the transition to multicellularity, the
emergence of eusociality in insect colonies, and the development of
full-fledged human societies. However, we lack a universal mechanism to explain
the emergence of cooperation across length scales, across species, and scalable
to large populations of individuals. We present a novel framework for modelling
cooperation games with an arbitrary number of players by combining reaction
networks, methods from quantum mechanics applied to stochastic complex systems,
game theory and stochastic simulations of molecular reactions. Using this
framework, we propose a novel and robust mechanism based on risk aversion that
leads to cooperative behaviour in population games. Rather than individuals
seeking to maximise payouts in the long run, individuals seek to obtain a
minimum set of resources with a given level of confidence and in a limited time
span. We explicitly show that this mechanism leads to the emergence of new Nash
equilibria in a wide range of cooperation games. Our results suggest that risk
aversion is a viable mechanism to explain the emergence of cooperation in a
variety of contexts and with an arbitrary number of individuals greater than
three.
A comparative theoretical study is presented for the rhombohedral R3 and R3m
phase HfO2, of two possible forms in its heavily Zr-doped ferroelectric thin
films found recently in experiments. Their structural stability and
polarization under the in-plane compressive strain are comprehensively
investigated. We discovered that there is a phase transition from R3 to R3m
phase under the biaxial compressive strain. Both the direction and amplitude of
their polarization can be tuned by the strain. By performing a symmetry mode
analysis, we are able to understand its improper nature of the
ferroelectricity. These results may help to shed light on the understanding of
the hafnia ferroelectric thin films.
The remarkable technical contributions of Michael E. Fisher to statistical
physics and the development of the renormalization group are widely known and
deeply influential. But less well-known is his early and profound appreciation
of the way in which renormalization group created a revolution in our
understanding of how physics -- in fact, all science -- is practiced, and the
concomitant adjustment that needs to be made to our conception of the purpose
and philosophy of science. In this essay, I attempt to redress this imbalance,
with examples from Fisher's writings and my own work. It is my hope that this
tribute will help remove some of the confusion that surrounds the scientific
usage of minimal models and renormalization group concepts, as well as their
limitations, in the ongoing effort to understand emergence in complex systems.
This paper will be published in "50 years of the renormalization group",
dedicated to the memory of Michael E. Fisher, edited by Amnon Aharony, Ora
Entin-Wohlman, David Huse and Leo Radzihovsky, World Scientific (in press).
ARPES studies of the protected surface states in the Topological Insulator $%
Bi_{2}Te_{3}$ have revealed the existence of an important hexagonal warping
term in its electronic band structure. This term distorts the shape of the
Dirac cone from a circle at low energies to a snowflake shape at higher
energies. We show that this implies important modifications of the interband
optical transitions which no longer provide a constant universal background as
seen in graphene. Rather the conductivity shows a quasilinear increase with a
slightly concave upward bending as energy is increased. Its slope increases
with increasing magnitude of the hexagonal distortion as does the magnitude of
the jump at the interband onset. The energy dependence of the density of states
is also modified and deviates downward from linear with increasing energy.
Charge Density Waves (CDW) are commonly associated with the presence of
near-Fermi level states which are separated from others, or "nested", by a
wavector of $\mathbf{q}$. Here we use Angle-Resolved Photo Emission
Spectroscopy (ARPES) on the CDW material Ta$_2$NiSe$_7$ and identify a total
absence of any plausible nesting of states at the primary CDW wavevector
$\mathbf{q}$. Nevertheless we observe spectral intensity on replicas of the
hole-like valence bands, shifted by a wavevector of $\mathbf{q}$, which appears
with the CDW transition. In contrast, we find that there is a possible nesting
at $\mathbf{2q}$, and associate the characters of these bands with the reported
atomic modulations at $\mathbf{2q}$. Our comprehensive electronic structure
perspective shows that the CDW-like transition of Ta$_2$NiSe$_7$ is unique,
with the primary wavevector $\mathbf{q}$ being unrelated to any low-energy
states, but suggests that the reported modulation at $\mathbf{2q}$, which would
plausibly connect low-energy states, might be more important for the overall
energetics of the problem.
Kramers nodal lines (KNLs) have recently been proposed theoretically as a
special type of Weyl line degeneracy connecting time-reversal invariant
momenta. KNLs are robust to spin orbit coupling and are inherent to all
non-centrosymmetric achiral crystal structures, leading to unusual spin,
magneto-electric, and optical properties. However, their existence in in real
quantum materials has not been experimentally established. Here we gather the
experimental evidence pointing at the presence of KNLs in SmAlSi, a
non-centrosymmetric metal that develops incommensurate spin density wave order
at low temperature. Using angle-resolved photoemission spectroscopy, density
functional theory calculations, and magneto-transport methods, we provide
evidence suggesting the presence of KNLs, together with observing Weyl fermions
under the broken inversion symmetry in the paramagnetic phase of SmAlSi. We
discuss the nesting possibilities regarding the emergent magnetic orders in
SmAlSi. Our results provide a solid basis of experimental observations for
exploring correlated topology in SmAlSi.
We demonstrate that non-diffusive, fluid-like heat transport, such as heat
backflowing from cooler to warmer regions, can be induced, controlled, and
amplified in extreme thermal conductors such as graphite and hexagonal boron
nitride. We employ the viscous heat equations, i.e. the thermal counterpart of
the Navier-Stokes equations in the laminar regime, to show with
first-principles quantitative accuracy that a finite thermal viscosity yields
steady-state heat vortices, and governs the magnitude of transient temperature
waves. Finally, we devise strategies that exploit devices' boundaries and
resonance to amplify and control heat hydrodynamics, paving the way for novel
experiments and applications in next-generation electronic and phononic
technologies.
Nominally identical materials exchange net electric charge during contact
through a mechanism that is still debated. `Mosaic models', in which surfaces
are presumed to consist of a random patchwork of microscopic donor/acceptor
sites, offer an appealing explanation for this phenomenon. However, recent
experiments have shown that global differences persist even between
same-material samples, which the standard mosaic framework does not account
for. Here, we expand the mosaic framework by incorporating global differences
in the densities of donor/acceptor sites. We develop an analytical model,
backed by numerical simulations, that smoothly connects the global and
deterministic charge transfer of different materials to the local and
stochastic mosaic picture normally associated with identical materials. Going
further, we extend our model to explain the effect of contact asymmetries
during sliding, providing a plausible explanation for reversal of charging sign
that has been observed experimentally.
Flexible strain gauges with 88% optical transmittance, of reduced graphene
oxide (rGO) on poly dimethylsiloxne membranes, are produced form monolayers of
graphene oxide assembled into densely packed sheets at an immiscible
hexane/water interface and subsequently reduced in HI vapor to increase
electrical conductivity. Pre-straining and relaxing the membranes introduces a
population of cracks into the rGO film. Subsequent straining opens these
cracks, inducing piezoresistivity. Reduction for 30 s forms an array of
parallel cracks that do not individually span the membrane and results in a
strain gauge with a usable strain range > 0.2 and gauge factor of 20 - 100 at
low strain levels that increases with increasing pre-strain. In all cases the
gauge facto decreases with increasing applied strain and asymptotes to a value
of about 3, as it approaches the pre-strain value. If the rGO is reduced for 60
s, the cracks fully span the width of the membrane, leading to an increased
gauge resistance but a much more sensitive strain gauge with GF ranging from
1000 - 16000. However, the usable strain range reduces to < 0.01. A simple
equivalent resistor model is proposed to describe the behaviour of both gauge
types. The gauges show a repeatable and stable response with loading
frequencies up to 1 kHz and have been used to detect human body motion in a
simple e-skin demonstration.
How multiple observables mutually influence their dynamics has been a crucial
issue in statistical mechanics. We introduce a new concept, "quantum velocity
limits," to establish a quantitative and rigorous theory for non-equilibrium
quantum dynamics for multiple observables. Quantum velocity limits are
universal inequalities for a vector the describes velocities of multiple
observables. They elucidate that the speed of an observable of our interest can
be tighter bounded when we have knowledge of other observables, such as
experimentally accessible ones or conserved quantities, compared with the
conventional speed limits for a single observable. We first derive an
information-theoretical velocity limit in terms of the generalized correlation
matrix of the observables and the quantum Fisher information. The velocity
limit has various novel consequences: (i) conservation law in the system, a
fundamental ingredient of quantum dynamics, can improve the velocity limits
through the correlation between the observables and conserved quantities; (ii)
speed of an observable can be bounded by a nontrivial lower bound from the
information on another observable; (iii) there exists a notable non-equilibrium
tradeoff relation, stating that speeds of uncorrelated observables, e.g.,
anti-commuting observables, cannot be simultaneously large; (iv) velocity
limits for any observables on a local subsystem in locally interacting
many-body systems remain convergent even in the thermodynamic limit. Moreover,
we discover another distinct velocity limit for multiple observables on the
basis of the local conservation law of probability current, which becomes
advantageous for macroscopic transitions of multiple quantities.
Non-Hermitian Floquet topological phases appear in systems described by
time-periodic non-Hermitian Hamiltonians. This review presents a sum-up of our
studies on non-Hermitian Floquet topological matter in one and two spatial
dimensions. After a brief overview of the literature, we introduce our
theoretical framework for the study of non-Hermitian Floquet systems and the
topological characterization of non-Hermitian Floquet bands. Based on our
theories, we describe typical examples of non-Hermitian Floquet topological
insulators, superconductors and quasicrystals with a focus on their topological
invariants, bulk-edge correspondences, non-Hermitian skin effects, dynamical
properties and localization transitions. We conclude this review by summarizing
our main discoveries and discussing potential future directions.
