Found 27 papers in cond-mat We present a theory unifying the topological responses and anomalies of
various gapless fermion systems exhibiting Fermi surfaces, including those with
Berry phases, and nodal structures, which applies beyond non-interacting limit.
As our key finding, we obtain a general approach to directly relate gapless
fermions and topological insulators in phase space, including first- and
higher-order insulators. Using this relation we show that the low-energy
properties and response theories for gapless fermionic systems can be directly
obtained without resorting to microscopic details. Our results provide a
unified framework for describing such systems using well-developed theories
from the study of topological phases of matter.
Flux attachment provides a powerful conceptual framework for understanding
certain forms of topological order, including most notably the fractional
quantum Hall effect. Despite its ubiquitous use as a theoretical tool, directly
realizing flux attachment in a microscopic setting remains an open challenge.
Here, we propose a simple approach to realizing flux attachment in a
periodically-driven (Floquet) system of either spins or hard-core bosons. We
demonstrate that such a system naturally realizes correlated hopping
interactions and provides a sharp connection between such interactions and flux
attachment. Starting with a simple, nearest-neighbor, free boson model, we find
evidence -- from both a coupled wire analysis and large-scale density matrix
renormalization group simulations -- that Floquet flux attachment stabilizes
the bosonic integer quantum Hall state at $1/4$ filling (on a square lattice),
and the Halperin-221 fractional quantum Hall state at $1/6$ filling (on a
honeycomb lattice). At $1/2$ filling on the square lattice, time-reversal
symmetry is instead spontaneously broken and bosonic integer quantum Hall
states with opposite Hall conductances are degenerate. Finally, we propose an
optical-lattice-based implementation of our model on a square lattice and
discuss prospects for adiabatic preparation as well as effects of Floquet
heating.
A charge density wave (CDW) represents an exotic state in which electrons are
arranged in a long range ordered pattern in low-dimensional materials. Although
our understanding of the fundamental character of CDW has been enriched after
extensive studies, its relationship with functional phenomena remains
relatively limited. Here, we show an unprecedented demonstration of a tunable
charge-spin interconversion (CSI) in graphene/1T-TaS$_2$ van der Waals
heterostructures by manipulating the distinct CDW phases in 1T-TaS$_2$. Whereas
CSI from spins polarized in all three directions are observed in the
heterostructure when the CDW phase does not show commensurability, the output
of one of the components disappears and the other two are enhanced when the CDW
phase becomes commensurate. The experimental observation is supported by
first-principles calculations, which evidence that chiral CDW multidomains are
at the origin of the switching of CSI. Our results uncover a new approach for
on-demand CSI in low-dimensional systems, paving the way for advanced
spin-orbitronic devices.
The copper substituted lead oxyapatite,
Pb$_{10-x}$Cu$_{x}$(PO$_{3.92(4)}$)$_{6}$O$_{0.96(3)}$ (x=0.94(6)) was studied
using neutron and x-ray diffraction and neutron spectroscopy techniques. The
crystal structure of the main phase of our sample, which has come to be
colloquially known as LK-99, is verified to possess a hexagonal structure with
space group $P 6_{3}/m$, alongside the presence of impurity phases Cu and
Cu$_2$S. We determine the primary substitution location of the Cu as the Pb1
($6h$) site, with a small substitution at the Pb2 ($4f$) site. Consequently, no
clear Cu-doping-induced structural distortion was observed in the investigated
temperature region between 10~K and 300~K. Specially, we did not observe a
reduction of coordinate number at the Pb2 site or a clear tilting of PO$_4$
tetrahedron. Magnetic characterization reveals a diamagnetic signal in the
specimen, accompanied by a very weak ferromagnetic component at 2 K. No
long-range magnetic order down to 10 K was detected by the neutron diffraction.
Inelastic neutron scattering measurements did not show magnetic excitations for
energies up to 350 meV. There is no sign of a superconducting resonance in the
excitation spectrum of this material. The measured phonon density of states
compares well with density functional theory calculations performed for the
main LK-99 phase and its impurity phases. Our study may shed some insight into
the role of the favored substitution site of copper in the absence of
structural distortion and superconductivity in LK-99.
We present a cavity-electromechanical system comprising a superconducting
quantum interference device which is embedded in a microwave resonator and
coupled via a pick-up loop to a 6 $\mu$g magnetically-levitated superconducting
sphere. The motion of the sphere in the magnetic trap induces a frequency shift
in the SQUID-cavity system. We use microwave spectroscopy to characterize the
system, and we demonstrate that the electromechanical interaction is tunable.
The measured displacement sensitivity of $10^{-7} \, \mathrm{m} /
\sqrt{\mathrm{Hz}}$, defines a path towards ground-state cooling of levitated
particles with Planck-scale masses at millikelvin environment temperatures.
We investigated the topological pumping charge of a dimerized Kitaev chain
with spatially modulated chemical potential, which hosts nodal loops in
parameter space and violates particle number conservation. In the simplest
case, with alternatively assigned hopping and pairing terms, we show that the
model can be mapped into the Rice-Mele model by a partial particle-hole
transformation and subsequently supports topological charge pumping as a
demonstration of the Chern number for the ground state. Beyond this special
case, analytic analysis shows that the nodal loops are conic curves. Numerical
simulation of a finite-size chain indicates that the pumping charge is zero for
a quasiadiabatic loop within the nodal loop and is $\pm 1$ for a quasiadiabatic
passage enclosing the nodal loop. Our findings unveil a hidden topology in a
class of Kitaev chains.
We provide a general formulation of the spin-orbit coupling on a 2D curved
surface. Considering the wide applicability of spin-orbit effect in
spinor-based condensed matter physics, a general spin-orbit formulation could
aid the study of spintronics, Dirac graphene, topological systems, and quantum
information on curved surfaces. Particular attention is then devoted to the
development of an important spin-orbit quantity known as the spin-orbit torque.
As devices trend smaller in dimension, the physics of local geometries on
spin-orbit torque, hence spin and magnetic dynamics shall not be neglected. We
derived the general expression of a spin-orbit anisotropy field for the curved
surfaces and provided explicit solutions in the special contexts of the
spherical, cylindrical and flat coordinates. Our expressions allow spin-orbit
anisotropy fields and hence spin-orbit torque to be computed over the entire
surfaces of devices of any geometry.
Moir\'e structures formed by twisting three layers of graphene with two
independent twist angles present an ideal platform for studying correlated
quantum phenomena, as an infinite set of angle pairs is predicted to exhibit
flat bands. Moreover, the two mutually incommensurate moir\'e patterns among
the twisted trilayer graphene (TTG) can form highly tunable moir\'e
quasicrystals. This enables us to extend correlated physics in periodic moir\'e
crystals to quasiperiodic systems. However, direct local characterization of
the structure of the moir\'e quasicrystals and of the resulting flat bands are
still lacking, which is crucial to fundamental understanding and control of the
correlated moir\'e physics. Here, we demonstrate the existence of flat bands in
a series of TTGs with various twist angle pairs and show that the TTGs with
different magic angle pairs are strikingly dissimilar in their atomic and
electronic structures. The lattice relaxation and the interference between
moir\'e patterns are highly dependent on the twist angles. Our direct spatial
mappings, supported by theoretical calculations, reveal that the localization
of the flat bands exhibits distinct symmetries in different regions of the
moir\'e quasicrystals.
Graphene holds great potential for superconductivity due to its pure
two-dimensional nature, the ability to tune its carrier density through
electrostatic gating, and its unique, relativistic-like electronic properties.
At present, we are still far from controlling and understanding graphene
superconductivity, mainly because the selective introduction of superconducting
properties to graphene is experimentally very challenging. Here, we have
developed a method that enables shaping at will graphene superconductivity
through a precise control of graphene-superconductor junctions. The method
combines the proximity effect with scanning tunnelling microscope (STM)
manipulation capabilities. We first grow Pb nano-islands that locally induce
superconductivity in graphene. Using a STM, Pb nano-islands can be selectively
displaced, over different types of graphene surfaces, with nanometre scale
precision, in any direction, over distances of hundreds of nanometres. This
opens an exciting playground where a large number of predefined
graphene-superconductor hybrid structures can be investigated with atomic scale
precision. To illustrate the potential, we perform a series of experiments,
rationalized by the quasi-classical theory of superconductivity, going from the
fundamental understanding of superconductor-graphene-superconductor
heterostructures to the construction of superconductor nanocorrals, further
used as "portable" experimental probes of local magnetic moments in graphene.
The lattice thermal conductivity of graphene is evaluated using a microscopic
model that takes into account the lattice's discrete nature and the phonon
dispersion relation within the Brillouin zone. The Boltzmann transport equation
is solved iteratively within the framework of three-phonon interactions without
taking into account the four-phonon scattering process. The Umklapp and normal
collisions are treated rigorously, thereby avoiding relaxation-time and
long-wavelength approximations. The mechanisms of the failures of these
approximations in predicting the thermal transport properties are discussed.
Evaluation of the thermal conductivity is performed at different temperatures
and frequencies and in different crystallite sizes. Reasonably good agreement
with the experimental data is obtained. The calculation reveals a critical role
of out-of-plane acoustic phonons in determining the thermal conductivity. The
out-of-plane acoustic phonons contribute greatly and the longitudinal and
transverse acoustic phonons make small contributions over a wide range of
temperatures and frequencies. The out-of-plane acoustic phonons dominate the
thermal conductivity due to their high density of states and restrictions
governing the anharmonic phonon scattering. The selection rule severely
restricts the phase space for out-of-plane phonon scattering due to reflection
symmetry. The optical phonon contribution cannot be neglected at higher
temperatures. Both Umklapp and normal processes must be taken into account in
order to predict the phonon transport properties accurately.
The molecular dynamics simulations were used to obtain the radius of gyration
of real ring polymer chains with different topological structures consisting of
360 monomers. We focus on the entropic force which is exerted by a dilute
solution of ring polymer chains of different topological structures with the
excluded volume interaction (EVI) in a good solvent on the confining parallel
walls of a slit geometry. We consider mixed boundary conditions of one
repulsive wall and the other one at the adsorption threshold. The obtained
molecular dynamics simulation results for a wide slit region demonstrate a
qualitative agreement with previous analytical results for ideal ring polymers.
These results could lead to interesting potential applications in materials
engineering and improve understanding of some biological processes suggested in
the paper. Additionally, they could be applied in micro- and
nano-electromechanical devices (MEMS and NEMS) in order to reduce the static
friction.
The interactions between different layers in van der Waals heterostructures
have a significant impact on the electronic and optical characteristics. By
utilizing the intrinsic dipole moment of Janus transition metal dichalcogenides
(TMDs), it is possible to tune these interlayer interactions. We systematically
investigate structural and electronic properties of Janus MoSSe
monolayer/graphene-like Aluminum Nitrides (MoSSe/g-AlN) heterostructures with
point defects by employing density functional theory calculations with the
inclusion of the nonlocal van der Waals correction. The findings indicate that
the examined heterostructures are energetically and thermodynamically stable,
and their electronic structures can be readily modified by creating a
heterostructure with the defects in g-AlN monolayer. This heterostructure
exhibits an indirect semiconductor with the band gap of 1.627 eV which is in
the visible infrared region. It can be of interest for photovoltaic
applications. When a single N atom or Al atom is removed from a monolayer of
g-AlN in the heterostructure, creating vacancy defects, the material exhibits
similar electronic band structures with localized states within the band gap
which can be used for deliberately tailoring the electronic properties of the
MoSSe/g-AlN heterostructure. These tunable results can offer exciting
opportunities for designing nanoelectronics devices based on MoSSe/g-AlN
heterojunctions.
In gapped bilayer graphene, similarly to conventional semiconductors, Coulomb
impurities (such as nitrogen donors) may determine the activation energy of its
conductivity and provide low temperature hopping conductivity. However, in
spite of importance of Coulomb impurities, nothing is known about their
electron binding energy $E_b$ in the presence of gates. To close this gap, we
study numerically the electron binding energy $E_b$ of a singly charged donor
in BN-enveloped bilayer graphene with the top and bottom gates at distance $d$
and gate-tunable gap $2\Delta$. We show that for $10 < d < 200$ nm and $1 <
\Delta < 100$ meV the ratio $E_b/\Delta$ changes from 0.4 to 1.5. The ratio
$E_b/\Delta$ stays close to unity because of the dominating role of the bilayer
polarization screening which reduces the Coulomb potential well depth to values
$\sim \Delta$. Still the ratio $E_b/\Delta$ somewhat decreases with growing
$\Delta$, faster at small $\Delta$ and slower at large $\Delta$. On the other
hand, $E_b/\Delta$ weakly grows with $d$, again faster at small $\Delta$ and
slower at large $\Delta$. We also studied the effect of trigonal warping and
found only a small reduction of $E_b/\Delta$.
Two-dimensional dilute magnetic semiconductors has been recently reported in
semiconducting transition metal dichalcogenides by the introduction of
spin-polarized transition metal atoms as dopants. This is the case of
vanadium-doped WS$_2$ and WSe$_2$ monolayers, which exhibits a ferromagnetic
ordering even above room temperature. However, a broadband characterization of
their electronic band structure and its dependence on vanadium concentration is
still lacking. Therefore, here we perform power-dependent photoluminescence,
resonant four-wave mixing, and differential reflectance spectroscopy to study
the optical transitions close to the A exciton energy of vanadium-doped WS$_2$
monolayers with distinct concentrations. Instead of a single A exciton peak,
vanadium-doped samples exhibit two photoluminescence peaks associated with
transitions to occupied and unoccupied bands. Moreover, resonant Raman
spectroscopy and resonant second-harmonic generation measurements revealed a
blueshift in the B exciton but no energy change in the C exciton as vanadium is
introduced in the monolayers. Density functional theory calculations showed
that the band structure is sensitive to the Hubbard \(U\) correction for
vanadium and several scenarios are proposed to explain the two
photoluminescence peaks around the A exciton energy region. Our work provides
the first broadband optical characterization of these two-dimensional dilute
magnetic semiconductors, shedding light on the novel electronic features of
WS$_{2}$ monolayers which are tunable by the vanadium concentration.
The chiral anomaly is one of the robust quantum effects in relativistic field
theories with a chiral symmetry where charges in chiral sectors appear to be
separately conserved. The chiral anomaly, which is often associated with a
renormalization-invariant topological term, is a violation of this conservation
law due to quantum effects. Such anomalies manifest in Weyl materials as an
electromagnetic field-induced transfer of charge between Fermi pockets.
However, the emergent nature of the conservation of chiral charge leads to
manifestations of the chiral anomaly response that depend on the details of the
system such as the strength of interactions. In this paper, we apply an
approach where the chiral symmetry in solid materials is replaced by the
combination of charge $U(1)$ gauge and spatial translation symmetry. The chiral
anomaly in this case is replaced by a mixed anomaly between the two symmetries
and the chiral charge can be defined as being proportional to the total
momentum. We show that the chiral anomaly associated with this chiral charge is
unrenormalized by interactions in contrast to other chiral charges in $(1+1)D$
whose renormalization is regularization dependent. In $(3+1)$D Weyl systems,
this chiral anomaly is equivalent to the charge transferred between Fermi
surfaces which can be measured through changes in Fermi-surface-enclosed
volume. We propose a pump-probe technique to measure this.
Symmetry-protected topological crystalline insulators (TCIs) have primarily
been characterized by their gapless boundary states. However, in time-reversal-
($\mathcal{T}$-) invariant (helical) 3D TCI$\unicode{x2014}$termed higher-order
TCIs (HOTIs)$\unicode{x2014}$the boundary signatures can manifest as a
sample-dependent network of 1D hinge states. We here introduce nested
spin-resolved Wilson loops and layer constructions as tools to characterize the
intrinsic bulk topological properties of spinful 3D insulators. We discover
that helical HOTIs realize one of three spin-resolved phases with distinct
responses that are quantitatively robust to large deformations of the bulk
spin-orbital texture: 3D quantum spin Hall insulators (QSHIs), "spin-Weyl"
semimetals, and $\mathcal{T}$-doubled axion insulator (T-DAXI) states with
nontrivial partial axion angles indicative of a 3D spin-magnetoelectric bulk
response and half-quantized 2D TI surface states originating from a partial
parity anomaly. Using ab-initio calculations, we demonstrate that
$\beta$-MoTe$_2$ realizes a spin-Weyl state and that $\alpha$-BiBr hosts both
3D QSHI and T-DAXI regimes.
In this work, we propose a modern view of the integer spin simple currents
which have played a central role in discrete torsion. We reintroduce them as
nonanomalous composite particles constructed from $Z_{N}$ parafermionic field
theories. These composite particles have an analogy with the Cooper pair in the
Bardeen-Cooper-Schrieffer theory and can be interpreted as a typical example of
anyon condensation. Based on these $Z_{N}$ anomaly free composite particles, we
propose a systematic construction of the cylinder partition function of $Z_{N}$
fractional quantum Hall effects (FQHEs). One can expect realizations of a class
of general topological ordered systems by breaking the bulk-edge correspondence
of the bosonic parts of these FQH models. We also give a brief overview of
various phenomena in contemporary condensed matter physics, such as $SU(N)$
Haldane conjecture, general gapless and gapped topological order with respect
to the quantum anomaly defined by charges of these simple currents and bulk and
boundary renormalization group flow. Moreover, we point out an analogy between
these FQHEs and 2d quantum gravities coupled to matter, and propose a $Z_{N}$
generalization of supersymmetry known as "fractional supersymmetry" in the
composite parafermionic theory and study its analogy with quark confinement.
Our analysis gives a simple but general understanding of the contemporary
physics of topological phases in the form of the partition functions derived
from the operator formalism.
In the past two decades another transistor based on conducting polymers,
called the organic electrochemical transistor (ECT) was shown and largely
studied. The main difference between organic ECTs and FETs is the mode and
extent of channel doping: while in FETs the channel only has surface doping
through dipoles, the mixed ionic-electronic conductivity of the channel
material in Organic ECTs enables bulk electrochemical doping. As a result, the
organic ECT maximizes conductance modulation at the expense of speed. Until now
ECTs have been based on conducting polymers, but here we show that MXenes, a
class of 2D materials beyond graphene, have mixed ionic-electronic properties
that enable the realization of electrochemical transistors (ECTs). We show that
the formulas for organic ECTs can be applied to these 2D ECTs and used to
extract parameters like mobility. These MXene ECTs have high transconductance
values but low on-off ratios. We further show that conductance switching data
measured using ECT, in combination with other in-situ ex-situ electrochemical
measurements, is a powerful tool for correlating the change in conductance to
that of redox state: to our knowledge, this is the first report of this
important correlation for MXene films. Many future possibilities exist for
MXenes ECTs, and we think other 2D materials with bandgaps can also form ECTs
with single or heterostructured 2D materials. 2D ECTs can draw great
inspiration and theoretical tools from the field of organic ECTs and have the
potential to considerably extend the capabilities of transistors beyond that of
conducting polymer ECTs, with added properties such as extreme heat resistance,
tolerance for solvents, and higher conductivity for both electrons and ions
than conducting polymers.
It is commonly assumed in spintronics and magnonics that localized spins
within antiferromagnets are in the N\'{e}el ground state (GS), as well as that
such state evolves, when pushed out of equilibrium by current or external
fields, according to the Landau-Lifshitz-Gilbert (LLG) equation viewing
localized spins as classical vectors of fixed length. On the other hand, the
true GS of antiferromagnets is highly entangled, as confirmed by very recent
neutron scattering experiments witnessing their entanglement. Although GS of
ferromagnets is always unentangled, their magnonic low-energy excitation are
superpositions of many-body spin states and, therefore, entangled. In this
study, we initialize quantum Heisenberg ferro- or antiferromagnetic chains
hosing localized spins $S=1/2$, $S=1$ or $S=5/2$ into unentangled pure state
and then evolve them by quantum master equations (QMEs) of Lindblad or
non-Markovian type, derived by coupling localized spins to a bosonic bath (such
as due to phonons) or by using additional ``reaction coordinate'' in the latter
case. The time evolution is initiated by applying an external magnetic field,
and entanglement of time-evolving {\em mixed} quantum states is monitored by
computing its logarithmic negativity. We find that non-Markovian dynamics
maintains some degree of entanglement, which shrinks the length of the vector
of spin expectation values, thereby making the LLG equation inapplicable.
Conversely, Lindbladian (i.e., Markovian) dynamics ensures that entanglement
goes to zero, thereby enabling quantum-to-classical (i.e., to LLG) transition
in all cases -- $S=1/2$, $S=1$ and $S=5/2$ ferromagnet or $S=5/2$
antiferromagnet -- {\em except} for $S=1/2$ and $S=1$ antiferromagnet. We also
investigate the stability of entangled antiferromagnetic GS upon suddenly
coupling it to the bosonic bath.
Recently topogical excitons have attracted much attention. However, studies
on the topological properties of excitons in one dimension are still rare. Here
we have computed the Zak phase for a generic one-dimensional dimerised
excitonic model. Tuning relevant hopping parameters gives rise to a rich
spectrum of physics, including non-trivial topological phase in uniform chain
unlike the conventional Su-Shcrieffer-Heeger model, topologically nontrivial
flat bands, and exotic fractional phase. a new concept of ``composite chiral
site" was developed to interpret the Zak phase of $\pi$ in our calculations.
Our finite-chain calculations substantiate topological edge states, providing
more information about their characteristics. Most importantly, in the first
time, a topological phase transition assisted by the Dexter electron exchange
process has been found.
The most widely used method for obtaining high-quality two-dimensional
materials is through mechanical exfoliation of bulk crystals. Manual
identification of suitable flakes from the resulting random distribution of
crystal thicknesses and sizes on a substrate is a time-consuming, tedious task.
Here, we present a platform for fully automated scanning, detection, and
classification of two-dimensional materials, the source code of which we make
openly available. Our platform is designed to be accurate, reliable, fast, and
versatile in integrating new materials, making it suitable for everyday
laboratory work. The implementation allows fully automated scanning and
analysis of wafers with an average inference time of 100 ms for images of 2.3
Mpixels. The developed detection algorithm is based on a combination of the
flakes' optical contrast toward the substrate and their geometric shape. We
demonstrate that it is able to detect the majority of exfoliated flakes of
various materials, with an average recall (AR50) between 67% and 89%. We also
show that the algorithm can be trained with as few as five flakes of a given
material, which we demonstrate for the examples of few-layer graphene, WSe$_2$,
MoSe$_2$, CrI$_3$, 1T-TaS$_2$ and hexagonal BN. Our platform has been tested
over a two-year period, during which more than $10^6$ images of multiple
different materials were acquired by over 30 individual researchers.
Generalized string-net models have been recently proposed in order to enlarge
the set of possible topological quantum phases emerging from the original
string-net construction. In the present work, we do not consider vertex
excitations and restrict to plaquette excitations, or fluxons, that satisfy
important identities. We explain how to compute the energy-level degeneracies
of the generalized string-net Hamiltonian associated to an arbitrary unitary
fusion category. In contrast to the degeneracy of the ground state, which is
purely topological, that of excited energy levels depends not only on the
Drinfeld center of the category, but also on internal multiplicities obtained
from the tube algebra defined from the category. For a noncommutative category,
these internal multiplicities result in extra nontopological degeneracies. Our
results are valid for any trivalent graph and any orientable surface. We
illustrate our findings with nontrivial examples.
In the field of 2D materials, transition metal dichalcogenides (TMDs) are
gaining attention for electronic applications. Our study delves into the
H-phase monolayer VS$_2$ of the TMD family, analyzing its electronic structure
and how strain affects its band structure using Density Functional Theory
(DFT). Using a variety of computational methods, we provide an in-depth view of
the electronic band structure. We find that strains between -5\% and +5\%
significantly affect the energy gap, with uniaxial strains having a stronger
effect than biaxial strains. Remarkably, compressive strains induce a phase
shift from semiconducting to metallic, associated with symmetry breaking and
changes in bond length. These findings not only deepen our understanding of the
electronic nuances of monolayer VS$_2$ under varying strains but also suggest
potential avenues for creating new electronic devices through strain
engineering.
The quantum nature of electron spin is crucial for establishing topological
invariants in real materials. Since the spin does not in general commute with
the Hamiltonian, some of the topological features of the material can be
extracted from its study. In insulating materials, the spin operator induces a
projected operator on valence states called the spin valence operator. Its
spectrum contains information with regard to the different phases of the spin
Chern class. If the spin valence spectrum is gapped, the spin Chern numbers are
constant along parallel planes thus defining spin Chern insulating materials.
If the spin valence spectrum is not gapped, the changes in the spin Chern
numbers occur whenever this spectrum is zero. Materials whose spin valence
spectrum is gapless will be denoted spin Weyl topological insulators and their
definition together with some of their properties will be presented in this
work. The classification of materials from the properties of the spin valence
operator provides a characterization that complements the existing list of
topological invariants.
Deconfined quantum criticality describes continuous phase transitions that
are not captured by the Landau-Ginzburg paradigm. Here, we investigate
deconfined quantum critical points in the long-range, anisotropic Heisenberg
chain. With matrix product state simulations, we show that the model undergoes
a continuous phase transition from a valence bond solid to an antiferromagnet.
We extract the critical exponents of the transition and connect them to an
effective field theory obtained from bosonization techniques. We show that
beyond stabilizing the valance bond order, the long-range interactions are
irrelevant and the transition is well described by a double frequency
sine-Gordon model. We propose how to realize and probe deconfined quantum
criticality in our model with trapped-ion quantum simulators.
The past decade has witnessed significant progress in topological materials
investigation. Symmetry-indicator theory and topological quantum chemistry
provide an efficient scheme to diagnose topological phases from only partial
information of wave functions without full knowledge of topological invariants,
which has resulted in a recent comprehensive materials search. However, not all
topological phases can be captured by this framework, and topological
invariants are needed for a more refined diagnosis of topological phases. In
this study, we present a systematic framework to construct topological
invariants for a large part of symmetry classes, which should be contrasted
with the existing invariants discovered through one-by-one approaches. Our
method is based on the recently developed Atiyah-Hirzebruch spectral sequence
in momentum space. As a demonstration, we construct topological invariants for
time-reversal symmetric spinful superconductors with conventional pairing
symmetries of all space groups, for which symmetry indicators are silent. We
also validate that the obtained quantities work as topological invariants by
computing them for randomly generated symmetric Hamiltonians. Remarkably, the
constructed topological invariants completely characterize $K$-groups in 159
space groups. Our topological invariants for normal conducting phases are
defined under some gauge conditions. To facilitate efficient numerical
simulations, we discuss how to derive gauge-independent topological invariants
from the gauge-fixed topological invariants through some examples. Combined
with first-principles calculations, our results will help us discover
topological materials that could be used in next-generation devices and pave
the way for a more comprehensive topological materials database.
Freestanding ferroelectric oxide membranes emerge as a promising platform for
exploring the interplay between topological polar ordering and dipolar
interactions that are continuously tunable by strain. Our investigations
combining density functional theory (DFT) and deep-learning-assisted molecular
dynamics simulations demonstrate that DFT-predicted strain-driven morphotropic
phase boundary involving monoclinic phases manifest as diverse domain
structures at room temperatures, featuring continuous distributions of dipole
orientations and mobile domain walls. Detailed analysis of dynamic structures
reveals that the enhanced piezoelectric response observed in stretched
PbTiO$_3$ membranes results from small-angle rotations of dipoles at domain
walls, distinct from conventional polarization rotation mechanism and adaptive
phase theory inferred from static structures. We identify a ferroelectric
topological structure, termed "dipole spiral," which exhibits a giant intrinsic
piezoelectric response ($>$320 pC/N). This helical structure, primarily
stabilized by entropy and possessing a rotational zero-energy mode, unlocks new
possibilities for exploring chiral phonon dynamics and dipolar
Dzyaloshinskii-Moriya-like interactions.
