Found 26 papers in cond-mat This thesis studies light-matter interactions in strong and weak coupling
regimes. In the first part, we study the formation and propagation of
exciton-polariton condensates in different microcavities in the strong coupling
regime. Exciton-polaritons are composite quasiparticles created as a result of
the strong coupling between microcavity photons and quantum well excitons. In
the first part of the thesis, we take a system of exciton-polaritons in a
Kagome lattice and show that an initially localized condensate propagates in a
specific direction in space in the presence of anisotropy in the lattice, and
the initially localized condensate experiences revivals. We also study the
formation of exciton-polariton condensates in two different lowest energy
states at an exciton-polariton microcavity and the transition from the higher
energy state to the ground state under pulsed and continuous wave excitation
conditions by using various pump profiles. In the second part of the thesis, we
study the valley selection rules for the optical transitions from impurity
states to the conduction band in two-dimensional Dirac materials, taking a
monolayer of MoS2 as an example, we focus on the weak light-matter coupling
regime. We find the spectrum of the light absorption coefficients and calculate
the photon-drag electric current density due to the impurity-band transitions.
In recent years, there has been a growing interest in flatband systems which
exhibit macroscopic degeneracies. These systems offer a valuable mathematical
framework for the extreme sensitivity to perturbations and interactions. This
sensitivity unveils a wide variety of exotic and unconventional physical
phenomena. Moreover, the progress in their experimental realization contributes
to the expanding landscape of exploration in this field. This thesis aims to
summarize all the works throughout the Ph.D. program. Firstly, an in-depth
exploration was conducted on the impact of weak quasiperiodic perturbations on
one-dimensional two-band all-bands-flat lattices. These tight-binding
Hamiltonian are diagonalized through a sequence of local unitary
transformations. By adjusting the quasiperiodic potential parameters, the key
achievement involves finding a critical-to-insulator transition and identifying
fractality edges in the flatband systems with quasiperiodic perturbations.
Next, the investigation delved into the effects of on-site interactions among
hard-core bosons in one- and two-dimensional cross-stitch lattices. One key
finding is that groundstate energy primarily depends on compact localized
states. Moreover, the presence of barriers of compact localized states trap
bosons, leading to the emergence of non-ergodic excitation and Hilbert space
fragmentation. Lastly, a compact localized eigenstate of the one-dimensional
diamond chain using an electric circuit was successfully generated via local
(linear and non-linear) driving. This achievement opens up a versatile circuit
platform for the generation of flatbands and holds promise for potential
applications in the field of quantum information. I hope these collective
efforts have expanded the frontiers of the field and made a meaningful
contribution to the scientific community.
The cooling of a Bose gas in finite time results in the formation of a
Bose-Einstein condensate that is spontaneously proliferated with vortices. We
propose that the vortex spatial statistics is described by a homogeneous
Poisson point process (PPP) with a density dictated by the Kibble-Zurek
mechanism (KZM). We validate this model using numerical simulations of the
two-dimensional stochastic Gross-Pitaevskii equation (SGPE) for both a
homogeneous and a hard-wall trapped condensate. The KZM scaling of the average
vortex number with the cooling rate is established along with the universal
character of the vortex number distribution. The spatial statistics between
vortices is characterized by analyzing the two-point defect-defect correlation
function, the corresponding spacing distributions, and the random tessellation
of the vortex pattern using the Voronoi cell area statistics. Combining the PPP
description with the KZM, we derive universal theoretical predictions for each
of these quantities and find them in agreement with the SGPE simulations. Our
results establish the universal character of the spatial statistics of
point-like topological defects generated during a continuous phase transition
and the associated stochastic geometry.
The fusion of non-Abelian anyons or topological defects is a fundamental
operation in measurement-only topological quantum computation. In topological
superconductors, this operation amounts to a determination of the shared
fermion parity of Majorana zero modes. As a step towards this, we implement a
single-shot interferometric measurement of fermion parity in an indium
arsenide-aluminum heterostructure with a gate-defined nanowire. The
interferometer is formed by tunnel-coupling the proximitized nanowire to
quantum dots. The nanowire causes a state-dependent shift of these quantum
dots' quantum capacitance of up to 1 fF. Our quantum capacitance measurements
show flux $h/2e$-periodic bimodality with a signal-to-noise ratio of 1 in 3.7
$\mu\text{s}$ at optimal flux values. From the time traces of the quantum
capacitance measurements, we extract a dwell time in the two associated states
that is longer than 1 ms at in-plane magnetic fields of approximately 2 T.
These results are consistent with a measurement of the fermion parity encoded
in a pair of Majorana zero modes that are separated by approximately 3 \textmu
m and subjected to a low rate of poisoning by non-equilibrium quasiparticles.
The large capacitance shift and long poisoning time enable a minimum
measurement error probability of $1\%$.
The significant surge in energy use and escalating environmental concerns
have sparked worldwide interest towards the study and implementation of solar
cell technology. Perovskite solar cells (PSCs) have garnered remarkable
attention as an emerging third-generation solar cell technology. This paper
presents an in-depth analysis of lead-free mixed halide double perovskites in
the context of their potential uses in solar cell technology. Through the
previous studies of various mixed halide double perovskite materials as
potential absorber layer materials, it has been observed that
Cs$_2$TiI$_{6-x}$Br$_x$ possesses promising characteristics. In this study,
simulations were conducted using SCAPS-1D software to explore all possible
combinations for x= 0 to 6. The materials for the Hole Transport Layer (HTL)
and Electron Transport Layer (ETL) and absorber layer, along with their optimal
thicknesses, are selected to yield the most promising results in terms of
open-circuit voltage (V$_{oc}$), short-circuit current density (J$_{sc}$), fill
factor (FF), and power conversion efficiency. A novel tolerance factor is
employed to assess structural stability of perovskites.
FTO/Cu$_2$O/Cs$_2$TiI$_5$Br$_1$/WS$_2$ emerges as the best combination in terms
of the efficiency with 19.03% but FTO/Cu$_2$O/Cs$_2$TiI$_2$Br$_4$/WS$_2$ shows
good stability with 13.31% efficiency.
The effect of pressure on the low-temperature states of the Re3Ge7 is
investigated by both electrical and Hall resistance and magnetization
measurements. At ambient pressure, the temperature dependent resistance of
Re3Ge7 behaves quasi-linearly from room temperature down to 60 K, then
undergoes a two-step metal-to-insulator transitions (MIT) at temperatures T1 =
59.4 K and T2 = 58.7 K which may be related to a structural phase transition or
occurrence of charge density wave ordering. Upon applying pressure, the
two-step (T1, T2) MIT splits into three steps (T1, T2 and T3) above 1 GPa, and
all traces of MITs are fully suppressed by ~8 GPa. Subsequently, the onset of
bulk superconductivity (SC) occurs between 10.8 and 12.2 GPa and persists to
our highest pressure of 26.8 GPa. At 12.2 GPa the superconducting transition
temperature, Tc, and upper critical field, Hc2 reach the maximum of Tc (onset)
~5.9 K and Hc2 (1.8 K) ~ 14 kOe. Our results not only present the observation
of SC under high pressure in Re3Ge7 but also delineate the interplay between SC
and other competing electronic states by creating a T - p phase diagram for
this potentially topologically nontrivial system Re3Ge7.
High-pressure studies on elements play an essential role in superconductivity
research, with implications for both fundamental science and applications. Here
we report the experimental discovery of surprisingly low pressure driving a
novel germanium allotrope into a superconducting state in comparison to that
for alpha-Ge. Raman measurements revealed structural phase transitions and
possible electronic topological transitions under pressure up to 58 GPa. Based
on pressure-dependent resistivity measurements, superconductivity was induced
above 2 GPa and the maximum Tc of 6.8 K was observed under 4.6 GPa.
Interestingly, a superconductivity enhancement was discovered during
decompression, indicating the possibility of maintaining pressure-induced
superconductivity at ambient pressure with better superconducting performance.
Density functional theory analysis further suggested that the electronic
structure of Ge (oP32) is sensitive to its detailed geometry and revealed that
disorder in the beta-tin structure leads to a higher Tc in comparison to the
perfect beta-tin Ge.
Intriguing Nernst effects offer the prospect of engineering micro- and
nano-sized thermoelectric devices, facilitating heat harvesting, energy
conversion, and directional temperature control. In this Letter, we establish a
theoretical analysis of the layer Nernst effect (LNE) in twisted moir\'{e}
layers subjected to a temperature gradient. Our analysis reveals the emergence
of a layer-contrasted Nernst voltage perpendicular to the direction of the
temperature gradient. This phenomenon arises from the trigonal warping of the
Fermi surface and the layer pseudomagnetic field. The Fermi surface's trigonal
warping, breaking intra-valley inversion symmetry, leads to an imbalance
between left and right movers, resulting in a non-vanishing LNE. We validate
our theoretical framework by applying it to twisted bilayer graphene (TBG).
Importantly, our findings indicate that the Nernst coefficient in TBG can reach
values as high as $\mu$A/K, surpassing those of previously known materials by
three orders of magnitude. These results provide a foundation for utilizing TBG
and other twisted moir\'{e} layers as promising platforms to explore layer
caloritronics and develop thermoelectric devices.
The discoveries of numerous exciting phenomena in twisted bilayer graphene
(TBG) are stimulating significant investigations on moir\'e structures that
possess a tunable moir\'e potential. Optical response can provide insights into
the electronic structures and transport phenomena of non-twisted and twisted
moir\'e structures. In this article, we review both experimental and
theoretical studies of optical properties such as optical conductivity,
dielectric function, non-linear optical response, and plasmons in moir\'e
structures composed of graphene, hexagonal boron nitride (hBN), and/or
transition metal dichalcogenides (TMDCs). Firstly, a comprehensive introduction
to the widely employed methodology on optical properties is presented. After,
moir\'e potential induced optical conductivity and plasmons in non-twisted
structures are reviewed, such as single layer graphene-hBN, bilayer
graphene-hBN and graphene-metal moir\'e heterostructures. Next, recent
investigations of twist-angle dependent optical response and plasmons are
addressed in twisted moir\'e structures. Additionally, we discuss how optical
properties and plasmons could contribute to the understanding of the many-body
effects and superconductivity observed in moir\'e structures.
We study the algebraic structure of electron density operators in gapless
Weyl fermion systems in $d=3,5,7,\cdots$ spatial dimensions and in topological
insulators (without any protecting symmetry) in $d=4,6,8,\cdots$ spatial
dimensions. These systems are closely related by the celebrated bulk-boundary
correspondence. Specifically, we study the higher bracket -- a generalization
of commutator for more than two operators -- of electron density operators in
these systems. For topological insulators, we show that the higher-bracket
algebraic structure of density operators structurally parallels with the
Girvin-MacDonald-Platzman algebra (the $W_{1+\infty}$ algebra), the algebra of
electron density operators projected onto the lowest Landau level in the
quantum Hall effect. By the bulk-boundary correspondence, the bulk
higher-bracket structure mirrors its counterparts at the boundary.
Specifically, we show that the density operators of Weyl fermion systems, once
normal-ordered with respect to the ground state, their higher bracket acquires
a c-number part. This part is an analog of the Schwinger term in the commutator
of the fermion current operators. We further identify this part with a cyclic
cocycle, which is a topological invariant and an element of Connes'
noncommutative geometry.
Probing ground-state quantum geometry and topology through optical response
is not only of fundamental interest, but it can also offer several practical
advantages. Here, using first-principles calculations on antiferromagnetic
topological insulator MnBi$_2$Te$_4$ thin films, we demonstrate how the
generalized optical weight arising from the absorptive part of the optical
conductivity can be used to probe the ground state quantum geometry and
topology. We show that three septuple layers MnBi$_2$Te$_4$ exhibit an enhanced
almost perfect magnetic circular dichroism for a narrow photon energy window in
the infrared region. We calculate the quantum weight in a few septuple layers
MnBi$_2$Te$_4$ and show that it far exceeds the lower bound provided by the
Chern number. Our results suggest that the well-known optical methods are
powerful tools for probing the ground state quantum geometry and topology.
In this work, we propose a novel approach to generate universal atomic
embeddings, significantly enhancing the representational and accuracy aspects
of atomic embeddings, which ultimately improves the accuracy of property
prediction. Moreover, we demonstrate the excellent transferability of universal
atomic embeddings across different databases and various property tasks. Our
approach centers on developing the CrystalTransformer model. Unlike traditional
methods, this model does not possess a fundamental graph network architecture
but utilizes the Transformer architecture to extract latent atomic features.
This allows the CrystalTransformer to mitigate the inherent topological
information bias of graph neural networks while maximally preserving the atomic
chemical information, making it more accurate in encoding complex atomic
features and thereby offering a deeper understanding of the atoms in materials.
In our research, we highlight the advantages of CrystalTransformer in
generating universal atomic embeddings through comparisons with current
mainstream graph neural network models. Furthermore, we validate the
effectiveness of universal atomic embeddings in enhancing the accuracy of model
predictions for properties and demonstrate their transferability across
different databases and property tasks through various experiments. As another
key aspect of our study, we discover the strong physical interpretability
implied in universal atomic embeddings through clustering and correlation
analysis, indicating the immense potential of our universal atomic embeddings
as atomic fingerprints.
The exquisite distortion in a Kekul$\'e\ $-Y (Kek-Y) superlattice merges the
two inequivalent Dirac cones (from the $K$- and the $K^\prime$- points) into
the highest symmetric $\Gamma$-point in the hexagonal Brillouin zone. Here we
report that a circularly polarised light not only opens up a topological gap at
the $\Gamma$-point but also lifts the valley degeneracy at that point. Endowed
with Floquet dynamics and by devising a scheme of high-frequency approximation,
we have proposed that the handedness (left/right) in polarised light offers the
possibility to realise the valley-selective circular dichroism in Kek-Y shaped
graphene superlattice. Also, the non-vanishing Berry curvature and enumeration
of valley resolved Chern number $\mathcal{C}_{K}/\mathcal{C}_{K^\prime}=+1/-1$
enable us to assign two pseudo-spin flavors (up/down) with the two valleys.
Thereby, the above observations confirm the topological transition suggesting
the ease of realising the valley quantum anomalous Hall (VQAH) state within the
photon-dressed Kek-Y. These findings further manifest a non-zero optical valley
polarisation which is maximum at the $\Gamma$-point. Our paper thus proposes an
optically switchable topological valley filter which is desirous in the
evolving landscape of valleytronics.
Twisted bilayer graphene is known to host isolated and relatively flat bands
near charge neutrality, when tuned to specific magic angles. Nonetheless, these
rotational misalignments, lying below 1.1 degrees, result in long-period
moir\'e crystals, whose anomalous electronic properties are hardly accessible
to reliable atomistic simulations. Here, we present a map of differently
stacked graphene sheets, at arbitrary rotation angles corresponding to precise
interplanar distances, into an equivalence class represented by magic-angle
twisted bilayer graphene. We determine the equivalence relation in the class
within a continuum model, and extend its definition to a tight-binding
approach. Then, we use density functional theory to suggest that the
magic-angle physics may be characterized by costly computational strategies on
a twisted bilayer geometry, with conveniently large stacking angles. Our
results may pave the way for an ab initio characterization of the
unconventional topological phases and related excitations, associated with
currently observed low-energy quasi-flat bands.
We set up and parametrize a Hubbard model for interacting quantum dots in
bilayer graphene and study double dots as the smallest multi-dot system. We
demonstrate the tunability of the spin and valley multiplets, Hubbard
parameters, and effective exchange interaction by electrostatic gate potentials
and the magnetic field. Considering both the long- and short-range Coulomb
interaction, we map out the various spin and valley multiplets and calculate
their energy gaps for different dot sizes and inter-dot separations. For
half-filling and large valley splittings, we derive and parametrize an
effective Heisenberg model for the quantum dot spins.
We present an atomically precise technique to create sulfur vacancies and
control their atomic configurations in single-layer MoS$_{2}$. It involves
adsorbed Fe atoms and the tip of a scanning tunneling microscope, which enables
single sulfur removal from the top sulfur layer at the initial position of Fe.
Using scanning tunneling spectroscopy, we show that the STM tip can also induce
two Jahn-Teller distorted states with reduced orbital symmetry in the sulfur
vacancies. Density functional theory calculations rationalize our experimental
results. Additionally, we provide evidence for molecule-like hybrid orbitals in
artificially created sulfur vacancy dimers, which illustrates the potential of
our technique for the development of extended defect lattices and tailored
electronic band structures.
Understanding nanoscale mechanisms responsible for the recently discovered
ferroelectric nematics can be helped by direct visualization of self-assembly
of strongly polar molecules. Here we report on scanning tunneling microscopy
(STM) studies of monomolecular layers of a ferroelectric nematic liquid crystal
on a reconstructed Au(111) surface. The monolayers are obtained by deposition
from a solution at ambient conditions. The adsorbed ferroelectric nematic
molecules self-assemble into regular rows with tilted orientation, resembling a
layered structure of a smectic C. Remarkably, each molecular dipole in this
architecture is oriented along the same direction giving rise to polar
ferroelectric ordering.
Artificial one- and two-dimensional lattices have emerged as a powerful
platform for the emulation of lattice Hamiltonians, the fundamental study of
collective many-body effects as well as phenomena arising from non-trivial
topology. Exciton-polaritons, bosonic part-light and part-matter
quasiparticles, combine pronounced nonlinearities with the possibility of
on-chip implementation. In this context, organic semiconductors, hosting
ultra-stable Frenkel excitons, embedded in a microcavity have proven to be
versatile contenders for the study of nonlinear many-body physics and bosonic
condensation, which also enable deployment at ambient conditions. Here, we
implement a well-controlled, high-quality optical lattice, hosting light-matter
quasi-particles. The realized polariton graphene presents with excellent cavity
quality factors, showing distinct signatures of Dirac cone and flatband
dispersions as well as polariton lasing at room temperature. This is realized
by filling coupled dielectric microcavities with the fluorescent protein
mCherry. We demonstrate the emergence of a coherent polariton condensate at
ambient conditions, profiting from coupling conditions as precise and
controllable as in state-of-the-art inorganic semiconductor-based systems,
without limitations due to e.g. lattice matching in epitaxial growth. This
progress allows straightforward extension to more complex systems, such as the
study of topological phenomena in two-dimensional lattices including
topological lasers and non-Hermitian optics.
Recent breakthroughs in Josephson diodes dangle the possibility of extending
conventional non-reciprocal electronics into the realm of superconductivity.
While a strong magnetic field is recognized for enhancing diode efficiency, it
concurrently poses a risk of undermining the essential superconductivity
required for non-dissipative devices. To circumvent the need for magnetic-based
tuning, we propose a field-effect Josephson diode based on the electrostatic
gate control of finite momentum Cooper pairs in asymmetric
spin-momentum-locking states. We propose two possible implementations of our
gate-controlled mechanism: (i) a topological field-effect Josephson diode in
time-reversal-broken quantum spin Hall insulators; and (ii) semiconductor-based
field-effect Josephson diodes attainable in current experimental setups
involving a Zeeman field and spin-orbit coupling. Notably, the diode efficiency
is highly enhanced in the topological field-effect Josephson diode because the
current carried by the asymmetric helical edge states is topologically
protected and can be tuned by local gates. In the proposed Josephson diode, the
combination of gates and asymmetric spin-momentum-locking nature is equivalent
to that of a magnetic field, thus providing an alternative electrical operation
in designing nonreciprocal superconducting devices.
A number of interesting physical phenomena have been discovered in
magic-angle twisted bilayer graphene (MATBG), such as superconductivity,
correlated gapped and gapless phases, etc. The gapped phases are believed to be
symmetry-breaking states described by mean-field theories, whereas gapless
phases exhibit features beyond mean field. This work, combining poor man's
scaling, numerical renormalization group, and dynamic mean-field theory,
demonstrates that the gapless phases are the heavy Fermi liquid state with some
symmetries broken and the others preserved. We adopt the recently proposed
topological heavy fermion model for MATBG with effective local orbitals around
AA-stacking regions and Dirac fermions surrounding them. At zero temperature
and most non-integer fillings, the ground states are found to be heavy Fermi
liquids and exhibit Kondo resonance peaks. The Kondo temperature $T_K$ is found
at the order of 1meV. A higher temperature than $T_K$ will drive the system
into a metallic LM phase where disordered LM's and a Fermi liquid coexist. At
integer fillings $\pm1,\pm2$, $T_K$ is suppressed to zero or a value weaker
than RKKY interaction, leading to Mott insulators or symmetry-breaking states.
This theory offers a unified explanation for several experimental observations,
such as zero-energy peaks and quantum-dot-like behaviors in STM, the
Pomeranchuk effect, and the saw-tooth feature of inverse compressibility, etc.
For future experimental verification, we predict that the Fermi surface in the
gapless phase will shrink upon heating - as a characteristic of the heavy Fermi
liquid. We also conjecture that the heavy Fermi liquid is the parent state of
the observed unconventional superconductivity because the Kondo screening
reduces the overwhelming Coulomb interaction (~60meV) to a rather small
effective interaction (~1meV) comparable to possible weak attractive
interactions.
Transition metal dichalcogenide superlattices provide an exciting new
platform for exploring and understanding a variety of phases of matter. The
moir\'e continuum Hamiltonian, of two-dimensional jellium in a modulating
potential, provides a fundamental model for such systems. Accurate computations
with this model are essential for interpreting experimental observations and
making predictions for future explorations. In this work, we combine two
complementary quantum Monte Carlo (QMC) methods, phaseless auxiliary field
quantum Monte Carlo and fixed-phase diffusion Monte Carlo, to study the ground
state of this Hamiltonian. We observe a metal-insulator transition between a
paramagnetic and a $120^\circ$ N\'eel ordered state as the moir\'e potential
depth and the interaction strength are varied. We find significant differences
from existing results by Hartree-Fock and exact diagonalization studies. In
addition, we benchmark density-functional theory, and suggest an optimal hybrid
functional which best approximates our QMC results.
Collective biological systems display power laws for macroscopic quantities
and are fertile probing grounds for statistical physics. Besides power laws,
natural insect swarms present strong scale-free correlations, suggesting
closeness to phase transitions. Swarms exhibit {\em imperfect} dynamic scaling:
their dynamical correlation functions collapse into single curves when written
as functions of the scaled time $t\xi^{-z}$ ($\xi$: correlation length, $z$:
dynamic exponent), but only for short times. Triggered by markers, natural
swarms are not invariant under space translations. Measured static and dynamic
critical exponents differ from those of equilibrium and many nonequilibrium
phase transitions. Here, we show that: (i) the recently discovered
scale-free-chaos phase transition of the harmonically confined Vicsek model has
a novel extended critical region for $N$ (finite) insects that contains several
critical lines. (ii) As alignment noise vanishes, there are power laws
connecting critical confinement and noise that allow calculating static
critical exponents for fixed $N$. These power laws imply that the unmeasurable
confinement strength is proportional to the perception range measured in
natural swarms. (iii) Observations of natural swarms occur at different times
and under different atmospheric conditions, which we mimic by considering
mixtures of data on different critical lines and $N$. Unlike results of other
theoretical approaches, our numerical simulations reproduce the previously
described features of natural swarms and yield static and dynamic critical
exponents that agree with observations.
Despite the recent successes of vanilla Graph Neural Networks (GNNs) on
various tasks, their foundation on pairwise networks inherently limits their
capacity to discern latent higher-order interactions in complex systems. To
bridge this capability gap, we propose a novel approach exploiting the rich
mathematical theory of simplicial complexes (SCs) - a robust tool for modeling
higher-order interactions. Current SC-based GNNs are burdened by high
complexity and rigidity, and quantifying higher-order interaction strengths
remains challenging. Innovatively, we present a higher-order Flower-Petals (FP)
model, incorporating FP Laplacians into SCs. Further, we introduce a
Higher-order Graph Convolutional Network (HiGCN) grounded in FP Laplacians,
capable of discerning intrinsic features across varying topological scales. By
employing learnable graph filters, a parameter group within each FP Laplacian
domain, we can identify diverse patterns where the filters' weights serve as a
quantifiable measure of higher-order interaction strengths. The theoretical
underpinnings of HiGCN's advanced expressiveness are rigorously demonstrated.
Additionally, our empirical investigations reveal that the proposed model
accomplishes state-of-the-art performance on a range of graph tasks and
provides a scalable and flexible solution to explore higher-order interactions
in graphs. Codes and datasets are available at
https://github.com/Yiminghh/HiGCN.
We present a theoretical study of an interaction-driven quantum phase diagram
of twisted bilayer MoTe$_2$ at hole filling factor $\nu_h=1$ as a function of
twist angle $\theta$ and layer potential difference $V_z$, where $V_z$ is
generated by an applied out-of-plane electric field. At $V_z=0$, the phase
diagram includes quantum anomalous Hall insulators in the intermediate $\theta$
regime and topologically trivial multiferroic states with coexisting
ferroelectricity and magnetism in both small and large $\theta$ regimes. There
can be two transitions from the quantum anomalous Hall insulator phase to
topologically trivial out-of-plane ferromagnetic phase, and finally to in-plane
120$^\circ$ antiferromagnetic phase as $|V_z|$ increases, or a single
transition without the intervening ferromagnetic phase. We show explicitly that
the spin vector chirality of various 120$^\circ$ antiferromagnetic states can
be electrically switched. We discuss the connection between the experimentally
measured Curie-Weiss temperature and the low-temperature magnetic order based
on an effective Heisenberg model with magnetic anisotropy.
The complex correlated charge density wave (CDW) phases of 1T-TaS2 have
attracted great attention due to their emergent quantum states, such as
intricate CDW phase, Mott-Hubbard state, superconductivity and quantum spin
liquid. The delicate interplay among the complex intra-/inter-layer
electron-electron and electron-lattice interactions is the fundamental
prerequisite of these exotic quantum states. Here, we report a real-space
titration-like investigation of correlated CDW state in 1T-TaS2 upon
hole-doping via low-temperature scanning tunneling microscopy (LT-STM). The
gradual increased hole-doping results in the sequential emergence of electron
voids, phase domains, stacking disordering and mixed phase/chiral domains
attributed to the reduced electron correlations. The achiral intermediate
ring-like clusters and nematic CDW states emerge at the intralayer chiral
domain wall and interlayer heterochiral stacking regions via the
chiral-overlapping configurations. The local reversible CDW manipulation is
further realized by the non-equilibrium transient charge-injections of STM
field-emission spectra. Our results provide an in-depth insight of this
intricate correlated CDW state, and pave a way to realize exotic quantum states
via the accurate tuning of interior interactions in correlated materials.
Charge conjugation (C), mirror reflection (R), time reversal (T), and fermion
parity $(-1)^{\rm F}$ are basic discrete spacetime and internal symmetries of
the Dirac fermions. In this article, we determine the group, called the C-R-T
fractionalization, which is a group extension of $\mathbb{Z}_2^{\rm
C}\times\mathbb{Z}_2^{\rm R}\times\mathbb{Z}_2^{\rm T}$ by the fermion parity
$\mathbb{Z}_2^{\rm F}$, and its extension class in all spacetime dimensions
$d$, for a single-particle fermion theory. For Dirac fermions, with the
canonical CRT symmetry $\mathbb{Z}_2^{\rm CRT}$, the C-R-T fractionalization
has two possibilities that only depend on spacetime dimensions $d$ modulo 8,
which are order-16 nonabelian groups, including the famous Pauli group. For
Majorana fermions, we determine the R-T fractionalization in all spacetime
dimensions $d=0,1,2,3,4\mod8$, which is an order-8 abelian or nonabelian group.
For Weyl fermions, we determine the C or T fractionalization in all even
spacetime dimensions $d$, which is an order-4 abelian group. For Majorana-Weyl
fermions, we only have an order-2 $\mathbb{Z}_2^{\rm F}$ group. We discuss how
the Dirac and Majorana mass terms break the symmetries C, R, or T. We study the
domain wall dimensional reduction of the fermions and their C-R-T
fractionalization: from $d$-dim Dirac to $(d-1)$-dim Dirac or Weyl; and from
$d$-dim Majorana to $(d-1)$-dim Majorana or Majorana-Weyl.

Similar to the corresponding skin effects caused by system boundaries, this phenomenon also originates from nontrivial topology. However, finding th… We establish a general Rashba Hamiltonian for trilayer graphene (TLG) by introducing an extrinsic layer-dependent Rashba spin-orbit coupling (SOC) arising from the off-plane inversion symmetry breaking. Our results indicate that the band spin splitting depends strongly on the layer distribution and … Topological phase transitions fall outside of the symmetry-breaking paradigm and therefore elude many traditional analytical methods. In particular, significant geometric features found in the set of reduced density matrices (RDMs) disappear in symmetry-preserving topological systems. By returning t…

Despite decades of research, the physics governing the reconnection process in many parameter regimes remains controversial. Contemporary reconnection … A realistic SU(N) interacting fermionic model reveals exotic quantum magnetic phases that occur at intermediate N, where the competition between distinct ordering tendencies gives rise to an intermediate quantum spin liquid phase featuring nontrivial topological order. A hidden-variable formalism allows for the characterization of topological properties of temporal networks with higher-order interactions.

Turbulence is triggered by simulating a flow of microparticles past an obstacle while controlling parameters such as the flow speed and particle charge with and without the presence of damping. It is found that turbulence in simulations with damping occurs after the formation of shock fronts and that the transition to turbulence follows the conventional pathway involving the intermittent emergence of turbulent puffs.
