Found 30 papers in cond-mat The characterization of ground states among all quantum states is an
important problem in quantum many-body physics. For example, the celebrated
entanglement area law for gapped Hamiltonians has allowed for efficient
simulation of 1d and some 2d quantum systems using matrix product states. Among
ground states, some types, such as cat states (like the GHZ state) or
topologically ordered states, can only appear alongside their degenerate
partners, as is understood from the theory of spontaneous symmetry breaking. In
this work, we introduce a new class of simple states, including the $W$ state,
that can only occur as a ground state alongside an exactly degenerate partner,
even in gapless or disordered models. We show that these states are never an
element of a stable gapped ground state manifold, which may provide a new
method to discard a wide range of 'unstable' entanglement area law states in
the numerical search of gapped phases. On the other hand when these degenerate
states are the ground states of gapless systems they possess an excitation
spectrum with $O(1/L^2)$ finite-size splitting. One familiar situation where
this special kind of gaplessness occurs is at a Lifshitz transition due to a
zero mode; a potential quantum state signature of such a critical point. We
explore pathological parent Hamiltonians, and discuss generalizations to higher
dimensions, other related states, and implications for understanding
thermodynamic limits of many-body quantum systems.
Heterostructures of two-dimensional transition metal dichalcogenides (TMDs)
are emerging as a promising platform for investigating exotic correlated states
of matter. Here, we propose to engineer Bose-Fermi mixtures in these systems by
coupling inter-layer excitons to doped charges in a trilayer structure. Their
interactions are determined by the inter-layer trion, whose spin-selective
nature allows excitons to mediate an attractive interaction between charge
carriers of only one spin species. Remarkably, we find that this causes the
system to become unstable to topological p+ip superconductivity at low
temperatures. We then demonstrate a general mechanism to develop and control
this unconventional state by tuning the trion binding energy using a
solid-state Feshbach resonance.
In this preview, we discuss how to combine concepts of Weyl fermions, amazing
electronic properties of bulk Weyl semimetals, and advances in molecular beam
epitaxy with the needs of semiconductor industry, through the fabrication of
TaAs thin films.
Recent experiments have uncovered a distinctive magnetic metal in
lightly-doped multilayer graphene, coined the \textit{quarter metal}. This
quarter metal consolidates all the doped carriers, originally distributed
evenly across the four (or twelve) Fermi surfaces of the paramagnetic state,
into one expansive Fermi surface by breaking time-reversal and/or inversion
symmetry. In this work, we map out a comprehensive mean-field phase diagram of
the quarter-metal in rhombohedral trilayer graphene within the four dimensional
parameter space spanned by the density $n_e$, interlayer electric potential
$U$, external magnetic field parallel to the two-dimensional material plane
$B_{\parallel}$ and Kane-Mele spin-orbit coupling $\lambda$. We found an
annular Lifshitz phase transition and a Ising-XY phase transition and locate
these phase boundaries on the experimental phase diagram. The movement of the
Ising-XY phase boundary offers insights into $\lambda$. Our analysis reveals
that it moves along the line $\partial n_e/\partial B_{\parallel} \sim
-0.5\times 10^{11} \text{cm}^{-2}\text{T}^{-1}$ within the
$n_e$-$B_{\parallel}$ parameter space when $\lambda=30\mu$eV. Additionally, we
estimated the in-plane spin susceptibility of the valley-Ising quarter-metal
$\chi_{_\parallel}\sim 8~\mu\text{eV} ~\text{T}^{-2}$. Beyond these
quantitative findings, two general principles emerge from our study: 1) The
valley-XY quarter metal's dominance in the $n_e-U$ parameter space grows with
an increasing number of layers due to the reduce valley polarization variations
within the Fermi sea. 2) Layer polarization near the band edge plays an
important role in aiding the re-entrance of the paramagnetic state at low
density. The insights derived from the quarter metal physics may shed light on
the complex behaviors observed in other regions of the phase diagram.
We here introduce the concept of fragile topological dislocation modes, which
are localized only in a fraction of a topological phase, while otherwise leak
into the bulk continuum. We show that such dislocation modes are hosted in an
obstructed atomic topological phase in the two-dimensional Su-Schrieffer-Heeger
model, but only in a finite region with an indirect gap at high energy. These
dislocation modes are realized as chiral pairs at finite energies with
protection stemming from a combination of the chiral (unitary particle-hole)
and the point group (C$_{4v}$) symmetries, but only when the indirect gap is
open. In this regime, we corroborate the stability of the defect modes by
following their localization and also by explicitly adding a weak chemical
potential disorder. Our findings, therefore, should be consequential for the
experimental observation of such modes in designer topological crystals and
classical metamaterials.
Granular flows are ubiquitous in nature with single flows traversing a wide
range of dynamic conditions from initiation to deposition. Basal forces exerted
by environmental granular flows are responsible for the generation of
observable seismic signals. To fully realize the benefit of seismic
measurements, basal granular forces must be linked to macroscopic internal flow
dynamics across a wide range of flow conditions. We utilize discrete element
simulations to observe dry and submerged granular flows under plane-shear and
inclined flow configurations, relating bulk kinematics and rheology to basal
forcing signals. We find that regardless of the flow geometry/initiation the
variance in basal forcing scales with a local non-dimensional shear-rate (or
inertial number I), and this scaling tracks four different flow regimes spanned
by our simulations: (1) an unsteady particle rearrangement regime when
$I<10^{-3}$, where basal forces are dominated by low frequencies; (2) an
intermediate regime when $10^{-3}< I<10^{-2}$, where granular temperature is
isotropic and basal forces start to become noise-like, (3) a transitional
regime at $10^{-2}<I<10^{-1}$, where the increase in basal tractions with
increasing shear-rates stalls as the granular bed dilates, partially destroying
the contact network and configurational memory, and (4) a fully collisional
regime when $I>10^{-1}$, where granular temperature is anisotropic in the
stream-wise direction, and the signal becomes white noise-like up to a cutoff
frequency that is dependent on particle size and shear-rate. This effort
suggests that basal forces, recorded in instrumented channels or inverted from
seismic signals, can be used to interpret complex granular processes in
geophysical flows.
Recent experiments reported that the magnetic field can drive the Lifshitz
transition and one-dimensional (1D) Weyl nodes in the quantum limit of
three-dimensional pentatellurides, as they own low carrier densities and can
achieve the extreme quantum limit at a low magnetic field. In this paper, we
will investigate the conditions for the existence of the 1D Weyl nodes and
their dc transport properties. We find that in the strong topological insulator
(TI) phase of ZrTe5, the formation of the Weyl nodes depends heavily on the
carrier density; while in the weak TI phase of HfTe5, the Weyl nodes are more
likely to appear. These behaviors are attributed to the fact that in the strong
and weak TI phases, the zeroth Landau levels exhibit opposite evolutions with
the magnetic field. Moreover, the signatures of the critical fields that
characterize the distinct behaviors of the system can be directly captured in
the conductivities.
To push upper boundaries of effective thermal conductivity in polymer
composites, a fundamental understanding of thermal transport mechanisms is
crucial. Although there is intensive simulation research, systematic
experimental investigation on thermal transport in polymer composites is
limited. To better understand thermal transport processes, we design polymer
composites with perfect fillers (graphite) and defective fillers (graphite
oxide); we choose polar polyvinyl alcohol (PVA) as a matrix model; and we
identify how thermal transport occurs across heterogeneous interfaces. Measured
thermal conductivities of in PVA/defective filler composites is higher than
those of PVA/perfect filler composites, while measured thermal conductivities
in defective fillers are lower than those of perfect fillers. An effective
quantum mechanical model is developed, showing that the vibrational state of
the defective level plays a critical role in enhancing the thermal conductivity
with increased defect concentration. Our experimental and model results have
suggested that defects in polymer composites may enhance thermal transport in
polymer composites by promoting vibrational resonant couplings.
A valley filter capable of generating a valley-polarized current is a crucial
element in valleytronics, yet its implementation remains challenging. Here, we
propose a valley filter made of a graphene bilayer which exhibits a 1D
moir\'{e} pattern in the overlapping region of the two layers controlled by
heterostrain. In the presence of a lattice modulation between layers, electrons
propagating in one layer can have valley-dependent dissipation due to valley
asymmetric interlayer coupling, thus giving rise to a valley-polarized current.
Such a process can be described by an effective non-Hermitian theory, in which
the valley filter is driven by a valley-resolved non-Hermitian skin effect.
Nearly 100\% valley-polarization can be achieved within a wide parameter range
and the functionality of the valley filter is electrically tunable. The
non-Hermitian topological scenario of the valley filter ensures high tolerance
against imperfections such as disorder and edge defects. Our work opens a new
route for efficient and robust valley filters while significantly relaxing the
stringent implementation requirements.
In this work, using binary Bose-Einstein condensate we propose a new type of
topological insulator that does not explicitly use specially designed potential
landscape, but instead utilizes spatially inhomogeneous Rabi coupling between
two components, in the form of one- or two-dimensional Su-Schrieffer-Heeger
(SSH) structure, combined with Zeeman splitting. Such Rabi lattices reveal the
appearance of topologically nontrivial phases (including higher-order ones)
controlled by spatial shift of the domains with enhanced coupling between
condensates within unit cells of the structure, where localized topological
states appear at the edges or in the corners of truncated Rabi lattice. We also
show that the properties of edge states, their spatial localization, and
location of their chemical potential within topological gap can be controlled
by interatomic interactions that lead to formation of gap topological edge
solitons bifurcating from linear edge states. Such solitons in condensates with
inhomogeneous Rabi coupling appear as very robust nonlinear topological objects
that do not require any threshold norm for their formation even in
two-dimensional geometries, and that can exist in stable form for both
attractive and repulsive interactions. Our results demonstrate considerable
enhancement of stability of solitons in topological Rabi lattices in comparison
with trivial Rabi lattices. They open new prospects for realization of
topologically nontrivial phases by spatial engineering of coupling in
multicomponent systems.
We formulate a generalized pseudospin formalism for multiband superconductors
in the presence of an external perturbing electromagnetic field. Our theory
naturally captures the effects of quantum band geometric quantities and is
valid even for flat-band superconductors. As an interesting consequence of our
theory, we show that there is an interband pairing fluctuations induced by the
external field and mediated by the quantum band geometry. Surprisingly, this
interband fluctuation is independent of the band gap, which can be understood
from the geometric nature of such novel fluctuations. We derive the generalized
equation of motion for the multiband pseudospin and the self-consistency
equation. We present a formal solution to the pseudospin equation of motion in
powers of the perturbing electromagnetic field. As a simple illustration of our
theory, we calculate the Leggett modes for the two band case.
The quasiparticles in the normal state of cuprate superconductors have been
shown to behave universally as a 3-dimensional Fermi liquid. Because of
interactions and the presence of the Fermi surfaces (or Fermi energies), the
quasiparticle energy contains, as a function of the momentum $\boldmath{p}$, a
term of the form $(p-p_0)^3 \ln ( | p-p_0 | / p_0 )$, where $p = | \boldmath{p}
|$ and $p_0$ is the Fermi momentum. The electronic specific heat coefficient
$\gamma(T)$, electrical resistivity, Hall coefficient and thermoelectric power
divided by temperature $T$, follow the logarithmic formula $a - b T^2 \ln (
T/T^*) $, $a$, $b$, and $T^*$ being constant. Singularities in the Landau
$f$-function produce the $T^2 \ln T$ dependence of the magnetic susceptibility
$\chi (T)$, and Knight shift, which gives rise to the phenomenon of the
susceptibility maximum. The logarithmic $T$-dependence of the transport
properties arises exclusively from the impurity scattering in 3-dimensional
(3D) systems, but does not from the electron-electron scattering in 2D systems.
The above logarithmic formula has been shown to explain universally the
experimental data for the normal state of all cuprate superconductors. The
decrease of $\gamma(T)$ or $\chi(T)$ with decreasing $T$ is not due to the
appearance of pseudogap or spin gap but due to its $T^2 \ln T$ variation.
In this study, a spin-1/2 anisotropic extended XY chain has been introduced
in which both time reversal and SU(2) symmetries are broken but $Z_2$ symmetry
is preserved. System exhibits the faithful coexistence of magnetic and
topological superconducting phases even in the presence of transverse magnetic
field. Location of those phases in the parameter space has been determined
precisely. Quantum phase transition is noted at zero magnetic field, as well as
magnetic long range order is found to withstand magnetic field of any strength.
Exact analytic results for spin-spin correlation functions have been obtained
in terms of Jordan Wigner fermionization. Existence of long range magnetic
order has been investigated numerically by finding correlation functions as
well as the Binder cumulant in the ground state. Dispersion relation, ground
state energy, and energy gap are obtained analytically. In order to find the
topologically nontrivial phase, sign of Pfaffian invariant and value of winding
number have been evaluated. Both magnetic and topological phases are robust
against the magnetic field and found to move coercively in the parameter space
with the variation of its strength. Long range orders along two orthogonal
directions and two different topological phases are found and their one-to-one
correspondence has been established. Finally casting the spinless fermions onto
Majorana fermions, properties of zero energy edge states are studied. Three
different kinds of Majorana pairings are noted. In the trivial phase,
next-nearest-neighbor Majorana pairing is found, whereas two different types of
nearest-neighbor Majorana pairings are identified in the topological
superconducting phase.
We develop a high-dimensional neural network potential (NNP) to describe the
structural and energetic properties of borophene deposited on silver. This NNP
has the accuracy of DFT calculations while achieving computational speedups of
several orders of magnitude, allowing the study of extensive structures that
may reveal intriguing moir\'e patterns or surface corrugations. We describe an
efficient approach to constructing the training data set using an iterative
technique known as the "adaptive learning approach". The developed NNP
potential is able to produce, with an excellent agreement, the structure,
energy and forces of DFT. Finally, the calculated stability of various
borophene polymorphs, including those not initially included in the training
dataset, shows better stabilization for $\nu\sim0.1$ hole density, and in
particular for the allotrope $\alpha$ ($\nu=\frac{1}{9}$). The stability of
borophene on the metal surface is shown to depend on its orientation, implying
structural corrugation patterns that can only be observed from long time
simulations on extended systems. The NNP also demonstrates its ability to
simulate vibrational densities of states and produce realistic structures, with
simulated STM images closely matching the experimental ones.
Swirling spin textures, including topologically non-trivial states, such as
skyrmions, chiral domain walls, and magnetic vortices, have garnered
significant attention within the scientific community due to their appeal from
both fundamental and applied points of view. However, their creation,
controlled manipulation, and stability are typically constrained to certain
systems with specific crystallographic symmetries, bulk, or interface
interactions, and/or a precise stacking sequence of materials. Here, we make
use of the stray field of YBa2Cu3O7-{\delta} superconducting microstructures in
ferromagnet/superconductor hybrids to imprint magnetic radial vortices in
permalloy at temperatures below the superconducting transition temperature
(TC), a method easily extended to other ferromagnets with in-plane magnetic
anisotropy. We examine the size dependence and temperature stability of the
imprinted magnetic configurations. We show that above TC, magnetic domains
retain memory of the imprinted spin texture. Micromagnetic modelling coupled
with a SC field model reveals that the stabilization mechanism leading to this
memory effect is mediated by microstructural defects. Superconducting control
of swirling spin textures below and above the superconducting transition
temperature holds promising prospects for shaping spintronics based on magnetic
textures.
The ability to modulate the spin-orbit (SO) interaction is crucial for
engineering a wide range of spintronics-based quantum devices, extending from
state-of-the-art data storage to materials for quantum computing. The use of
proximity-induced effects for this purpose may become the mainstream approach,
whereas their experimental verification using angle-resolved photoelectron
spectroscopy (ARPES) has so far been elusive. Here, using the advantages of
soft-X-ray ARPES on its probing depth and intrinsic resolution in
three-dimensional momentum k, we identify a distinct modulation of the SO
interaction in a van der Waals semiconductor (MoSe2) proximitized to a high-Z
metal (Pb), and measure its variation through the k-space. The strong SO field
from Pb boosts the SO splitting by up to 30% at the H-point of the bulk
Brillouin zone, the spin-orbit hotspot of MoSe2. Tunability of the splitting
via the Pb thickness allows its tailoring to particular applications in
emerging quantum devices.
Anomalous Hall effect (AHE), one of the most important electronic transport
phenomena, generally appears in ferromagnetic materials but is rare in
materials without magnetic elements. Here, we present a study of
La$_3$MgBi$_5$, whose band structure carries multitype Dirac fermions. Although
magnetic elements are absent in La$_3$MgBi$_5$, clear signals of AHE can be
observed. In particular, the anomalous Hall conductivity is extremely large,
reaching 42,356 $\Omega^{-1}$ cm$^{-1}$ with an anomalous Hall angle of 8.8 %,
the largest one that has been observed in the current AHE systems. The AHE is
suggested to originate from the combination of skew scattering and Berry
curvature. Another unique property discovered in La$_3$MgBi$_5$ is the axial
diamagnetism. The diamagnetism is significantly enhanced and dominates the
magnetization in the axial directions, which is the result of restricted motion
of the Dirac fermion at Fermi level. Our findings not only establish
La$_3$MgBi$_5$ as a suitable platform to study AHE and quantum transport, but
also indicate the great potential of 315-type Bi-based materials for exploring
novel physical properties.
In the quest for efficient and cost-effective photovoltaic absorber materials
beyond silicon, considerable attention has been directed toward exploring
alternatives. One such material, zincblende-derived Cu2ZnSnS4 (CZTS), has shown
promise due to its ideal band-gap size and high absorption coefficient.
However, challenges such as structural defects and secondary phase formation
have hindered its development. In this study, we examine the potential of
another compound Cu2ZnSnO4 (CZTO) with a similar composition to CZTS as a
promising alternative. Employing ab initio density function theory (DFT)
calculations in combination with an evolutionary structure prediction
algorithm, we identify that the crystalline phase of the delafossite structure
is the most stable among the 900 (meta)stable CZTO. Its thermodynamic stability
at room temperature is also confirmed by the molecular dynamics study.
Excitingly, this new phase of CZTO displays a direct band gap where the
dipole-allowed transition occurs, making it a strong candidate for efficient
light absorption. Furthermore, the estimation of spectroscopic limited maximum
efficiency (SLME) directly demonstrates the high potential of delafossite-CZTO
as a photovoltaic absorber. Our numerical results suggest that delafossite-CZTO
holds another promise for future photovoltaic applications.
Exploring the bulk-boundary correspondences and the boundary-induced
phenomena in the strongly-correlated quantum systems belongs to the most
fundamental topics of condensed matter physics. In this work, we study the
bulk-boundary competition in a simulative Hamiltonian, with which the
thermodynamic properties of the infinite-size translationally-invariant system
can be optimally mimicked. The simulative Hamiltonian is constructed by
introducing local interactions on the boundaries, coined as the
entanglement-bath Hamiltonian (EBH) that is analogous to the heat bath. The
terms within the EBH are variationally determined by a thermal tensor network
method, with coefficients varying with the temperature of the infinite-size
system. By treating the temperature as an adjustable hyper-parameter of the
EBH, we identify a discontinuity point of the coefficients, dubbed as the
``boundary quench point'' (BQP), whose physical implication is to distinguish
the point, below which the thermal fluctuations from the boundaries to the bulk
become insignificant. Fruitful phenomena are revealed when considering the
simulative Hamiltonian, with the EBH featuring its own hyper-parameter, under
the canonical ensembles at different temperatures. Specifically, a
discontinuity in bulk entropy at the BQP is observed. The exotic entropic
distribution, the relations between the symmetries of Hamiltonian and BQP, and
the impacts from the entanglement-bath dimension are also explored. Our results
show that such a singularity differs from those in the conventional
thermodynamic phase transition points that normally fall into the
Landau-Ginzburg paradigm. Our work provides the opportunities on exploring the
exotic phenomena induced by the competition between the bulk and boundaries.
We explore the spin density and charge currents arising on the surface of a
topological insulator and in a 2D Rashba metal due to magnetization gradients.
For topological insulators a single interconversion coefficient controls the
generation of both quantities. This coefficient is quantized to a value
proportional to the vorticity of the Dirac point which constitutes a hallmark
of parity anomaly at finite density. As such, it also unveils a robust route to
disentangle and detect the protected states of a topological insulator on a
given surface. In stark contrast, Rashba metals do not exhibit such anomalies
since they contain an even number of helical branches. Nonetheless, also these
are governed by quantized responses which, however, are not protected against
weak disorder. Furthermore, we find that for Rashba metals the interconversion
coefficients demonstrate discontinuities and a nontrivial interplay upon
varying the chemical potential, the strength of the spin-orbit coupling, and a
pairing gap. Our results have implications for the binding between magnetic
skyrmions and superconducting vortices, the emergence of Majorana zero modes,
and pave the way for superconducting diode effects mediated by out-of-plane
magnetization gradients.
The migration of helical particles in viscous shear flows plays a crucial
role in chiral particle sorting. Attaching a non-chiral head to a helical
particle leads to a rheotactic torque inducing particle reorientation. This
phenomenon is responsible for bacterial rheotaxis observed for flagellated
bacteria as Escherichia coli in shear flows. Here we use a high-resolution
microprinting technique to fabricate micro-particles with controlled and
tunable chiral shape consisting of a spherical head and helical tails of
various pitch and handedness. By observing the fully time-resolved dynamics of
these micro-particles in microfluidic channel flow, we gain valuable insights
into chirality-induced orientation dynamics. Our experimental model system
allows us to examine the effects of particle elongation, chirality, and
head-heaviness for different flow rates on the orientation dynamics, while
minimizing the influence of Brownian noise. Through our model experiments we
demonstrate the existence of asymmetric bistability of the particle orientation
perpendicular to the flow direction. We quantitatively explain the particle
equilibrium orientations as a function of particle properties, initial
conditions and flow rates, as well as the time-dependence of the reorientation
dynamics through a theoretical model. The model parameters are determined using
boundary element simulations and excellent agreement with experiments is
obtained without any adjustable parameters. Our findings lead to a better
understanding of chiral particle transport, bacterial rheotaxis and might allow
the development of targeted delivery applications.
Broadening the variety of two-dimensional (2D) materials and improving the
synthesis of ultrathin films are crucial to the development of the
semiconductor industry. As a state-of-the-art 2D material, Ga2Se2 has
attractive optoelectronic properties when it reaches the atomically-thin
regime. However, its van der Waals epitaxial growth, especially for the
atomically-thin films, has seldom been studied. In this paper, we used
molecular beam epitaxy to synthesize Ga2Se2 single-crystal films with a surface
roughness down to 1.82 nm on c-plane sapphire substrates by optimizing
substrate temperature, Se:Ga flux ratio, and growth rate. Then we used a 3-step
mode to grow Ga2Se2 films with a thickness as low as 3 tetralayers and a
surface roughness as low as 0.61 nm, far exceeding the performance of direct
growth. Finally, we found that the surface morphology strongly depends on the
Se:Ga flux ratio, and higher growth rates widened the suitable flux ratio
window for growing Ga2Se2. Overall, this work advances the understanding of the
vdW epitaxy growth mechanism for post-transition metal monochalcogenides on
sapphire substrates.
Anyons are particles obeying statistics of neither bosons nor fermions.
Non-Abelian anyons, whose exchanges are described by a non-Abelian group acting
on a set of wave functions, are attracting a great attention because of
possible applications to topological quantum computations. Braiding of
non-Abelian anyons corresponds to quantum computations. The simplest
non-Abelian anyons are Ising anyons which can be realized by Majorana fermions
hosted by vortices or edges of topological superconductors, $\nu =5/2$ quantum
Hall states, spin liquids, and dense quark matter. While Ising anyons are
insufficient for universal quantum computations, Fibonacci anyons present in
$\nu =12/5$ quantum Hall states can be used for universal quantum computations.
Yang-Lee anyons are non-unitary counterparts of Fibonacci anyons. Another
possibility of non-Abelian anyons (of bosonic origin) is given by vortex
anyons, which are constructed from non-Abelian vortices supported by a
non-Abelian first homotopy group, relevant for certain nematic liquid crystals,
superfluid $^3$He, spinor Bose-Einstein condensates, and high density quark
matter. Finally, there is a unique system admitting two types of non-Abelian
anyons, Majorana fermions (Ising anyons) and non-Abelian vortex anyons. That is
$^3P_2$ superfluids (spin-triplet, $p$-wave paring of neutrons), expected to
exist in neutron star interiors as the largest topological quantum matter in
our universe.
Transition metal dichalcogenides (TMDCs) combine both strong
light-matter-interaction and strong Coulomb-interaction for the formation of
optically excitable excitons. Through radiative feedback control, a mechanism
to control the linewidth can be applied, which modifies optical transition
spectra. Here, we extend these investigations to the absorption spectra of
TMDCs in a variety of geometries with respect to non-Markovian
exciton-phonon-scattering contributions. Our approach is based on the self
consistent solution of the microscopic Bloch equations and the macroscopic
solution of the wave equation. We discuss the formation of a phonon sideband
for MoSe$_2$ embedded in SiO$_2$, and two setups for enhancing or suppressing
the phonon sideband in the spectrum.
Excitations in the form of quantized vortex rings are known to exist in
superfluid $^{4}He$ at energies and momenta exceeding those of the Landau
phonon-roton spectrum. They form a vortex branch of elementary excitations
spectrum which is disconnected from the Landau spectrum. Interference of vortex
ring excitations determines wake patterns due to uniformly traveling sources in
bulk superfluid at low speeds and pressures. The dispersion law of these
excitations resembles that of gravity waves on deep water with infrared wave
number cutoff. As a result, vortex wake patterns featuring elements of the
Kelvin ship wake are predicted. Specifically, at lowest speeds the pattern with
fully developed transverse and diverging wavefronts is present. At intermediate
speeds transverse wavefronts are absent within a cone whose opening angle
increases with the source velocity. At largest speeds only diverging wavefronts
confined within a cone whose opening angle decreases with the source velocity
are found. When experimentally observed, these changes in appearance of wake
patterns serve as indicators of the beginning part of the vortex branch of
elementary excitations.
Electrons can organize themselves into charge-ordered states to minimize the
effects of long-ranged Coulomb interactions. In the presence of a lattice,
commensurability constraints lead to the emergence of incompressible
Wigner-Mott (WM) insulators at various rational electron fillings, $\nu~=p/q$.
The mechanism for quantum fluctuation-mediated melting of the WM insulators
with increasing electron kinetic energy remains an outstanding problem. Here we
analyze numerically the bandwidth-tuned transition out of the WM insulator at
$\nu=1/5$ on infinite cylinders with varying circumference. For the two-leg
ladder, the transition from the WM insulator to the Luttinger liquid proceeds
via a distinct intermediate phase with gapless Cooper-pairs and gapped
electronic excitations. The resulting Luther-Emery liquid is the analog of a
strongly fluctuating superconductor. We place these results in the context of a
low-energy bosonization based theory for the transition. On the five-leg
cylinder, we provide numerical evidence for a direct continuous transition
between the WM insulator and a metallic phase across which the spin and
charge-gaps vanish simultaneously. We comment on the connections to ongoing
experiments in dual-gated bilayer moir\'e transition metal dichalcogenide
materials.
Global symmetries greatly enrich the landscape of topological quantum phases,
playing an essential role from topological insulators to fractional quantum
Hall effect. Topological phases in mixed quantum states, originating from
decoherence in open quantum systems or disorders in imperfect crystalline
solids, have recently garnered significant interest. Unlike pure states, mixed
quantum states can exhibit average symmetries -- symmetries that keep the total
ensemble invariant but not on each individual state. In this work, we present a
systematic classification and characterization of average symmetry-protected
topological (ASPT) phases applicable to generic symmetry groups, encompassing
both average and exact symmetries, for bosonic and fermionic systems. Moreover,
we formulate the theory of average symmetry-enriched topological (ASET) orders
in disordered bosonic systems. Our systematic approach helps clarify nuanced
issues in previous literature and uncovers compelling new physics. Notably, we
discover that (1) the definition and classification of ASPT phases in decohered
and disordered systems exhibit subtle differences; (2) despite these
differences, ASPT phases in both settings can be classified and characterized
under a unified framework of defect decoration and spectral sequence; (3) this
systematic classification uncovers a plethora of ASPT phases that are
intrinsically mixed, implying they can exclusively manifest in decohered or
disordered systems where part of the symmetry is average; (4) similarly for
ASET, we find intrinsically disordered phases exhibiting exotic anyon behaviors
-- the ground states of such phases necessarily contain localized anyons, with
gapless (yet still localized) excitation spectral.
We present the first successful application of the matrix product state (MPS)
representing a thermal quantum pure state (TPQ) in equilibrium in two spatial
dimensions over almost the entire temperature range. We use the Kitaev
honeycomb model as a prominent example hosting a quantum spin liquid (QSL)
ground state to target the two specific-heat peaks previously solved nearly
exactly using the free Majorana fermionic description. Starting from the
high-temperature random state, our TPQ-MPS framework on a cylinder precisely
reproduces these peaks, showing that the quantum many-body description based on
spins can still capture the emergent itinerant Majorana fermions in a ${\mathbb
Z}_2$ gauge field. The truncation process efficiently discards the high-energy
states, eventually reaching the long-range entangled topological state
approaching the exact ground state for a given finite size cluster. An
advantage of TPQ-MPS over exact diagonalization or purification-based methods
is its lowered numerical cost coming from a reduced effective Hilbert space
even at finite temperature.
Probabilistic computing is a novel computing scheme that offers a more
efficient approach than conventional CMOS-based logic in a variety of
applications ranging from optimization to Bayesian inference, and invertible
Boolean logic. The probabilistic-bit (or p-bit, the base unit of probabilistic
computing) is a naturally fluctuating entity that requires tunable
stochasticity; by coupling low-barrier stochastic Magnetic Tunnel Junctions
(MTJs) with a transistor circuit, a compact implementation is achieved. In this
work, through integrating stochastic MTJs with 2D-MoS$_{2}$ FETs, the first
on-chip realization of a key p-bit building block displaying
voltage-controllable stochasticity is demonstrated. In addition, supported by
circuit simulations, this work provides a careful analysis of the three
transistor-one magnetic tunnel junction (3T-1MTJ) p-bit design, evaluating how
the characteristics of each component influence the overall p-bit output. This
understanding of the interplay between the characteristics of the transistors
and the MTJ is vital for the construction of a fully functioning p-bit, making
the design rules presented in this article key for future experimental
implementations of scaled on-chip p-bit networks.
Random packings of stiff rods are self-supporting mechanical structures
stabilized by their geometrical and topological complexity. To understand why,
we deploy X-ray computerized tomography to unveil the structure of the packing.
This allows us to define and directly visualize the spatial variations in
"entanglement," a mesoscopic field that characterizes the local average
crossing number, a measure of the topological complexity of the packing. We
show that the entanglement field has information that is distinct from the
density, orientational order, and contact distribution of the packing. We find
that increasing the aspect ratio of the constituent rods in a packing leads to
an abrupt change in the entanglement, correlated with a sharp transition in the
mechanical response of the packing. This leads to an entanglement phase diagram

When a quantum-dot electron spin is electrically driven to perform coherent Rabi oscillations, it can polarize nuclear spins through a resonance analogous to the Hartmann-Hahn effect known from NMR. Here, the authors theoretically analyze such a polarization rate in a generic setup including GaAs, Si, and Ge, and both electron and hole spin qubits. They present measurements in $n$-GaAs and estimate that the effect is also observable in Si. It might offer control over the Overhauser nuclear field in gated quantum dots. [Phys. Rev.

The scattering matrix is a crucial characterization of a physical system. The authors present here a systematic topological theory of scattering matrices, focusing on their singular values and vectors. They identify topological characteristics such as winding number, Berry phase, and skew polarization. The theory uncovers the topological nature of coherent perfect absorption and introduces coherent perfect extinction, where a coherent wave is completely extinguished through interference. These findings advance the understanding of scattering and have implications for novel wave devices. [Phys. Rev. B 108, 155418] Published Tue Oct 17, 2023 |

The authors investigate here the dynamics of free fermions in a random potential system under continuous monitoring. Repeated measurements are known to induce an entanglement phase transition from a logarithmically entangled critical state to area law, while disorder leads to Anderson localization. They show that their interplay results in a stable critical phase at finite disorder strength and dissipation, which drive a transition consistent with Berezinskii-Kosterlitz-Thouless universality. This work is important for testing such phase transitions in quantum dot arrays and nanowires. [Phys. Rev. B 108, 165126] Published Tue Oct 17, 2023 |
