Found 18 papers in cond-mat We show how the $\mathbb{Z}_{2}$ topological index of a one-dimensional
topological p-wave superconductor can be revealed when driving with a classical
vector potential i.e. an electromagnetic wave, through the quasiparticles
inter-band transition rates. As a function of driving frequency $\omega$, it is
possible to obtain a measure of this topological invariant from the resonance
envelope classifying the two distinct topological phases of the short-range
Kitaev wire. We also propose to probe the topological phase transition in the
model through the responses of the global capacitance in the presence of the
light field and also through the Josephson current between the wire and the
proximity coupled bulk superconductor. The system may also be implemented on
the Bloch sphere allowing alternative ways to measure the $\mathbb{Z}$ and
$\mathbb{Z}_2$ topological invariants through circuit or cavity quantum
electrodynamics.
Using unbiased Monte Carlo simulations and variational analysis, we present
the ground state and finite temperature phase diagrams of an exactly solvable
spin-orbital model with Kitaev-type interactions on a square lattice. We show
that an array of new gapped and gapless vison crystals -- characterized by the
periodic arrangement of $\mathbb{Z}_2$ flux excitations -- can be stabilized as
a function of external magnetic field and exchange anisotropy. In particular,
we discover a variety of `quarter phases' wherein new sixteen-site periodic
patterns emerge, with only a quarter of the fluxes adopting 0-flux
configurations. In contrast, the rest remain in $\pi$-flux configurations.
Vison crystals break translational symmetry and undergo finite temperature
phase transitions. We investigate the finite temperature properties of these
phases and report the corresponding critical and crossover temperatures. Our
results reveal an array of novel phases in exactly solvable extensions of the
Kitaev model, wherein local and topological orders can coexist.
Charge density waves (CDWs) appear in numerous condensed matter platforms,
ranging from high-Tc superconductors to quantum Hall systems. Despite such
ubiquity, there has been a lack of direct experimental study on boundary states
that can uniquely stem from the charge order. Here, using scanning tunneling
microscopy, we directly visualize the bulk and boundary phenomenology of CDW in
a topological material, Ta2Se8I. Below the transition temperature (TCDW = 260
K), tunneling spectra on an atomically resolved lattice reveal a large
insulating gap in the bulk and on the surface, exceeding 500 meV, surpassing
predictions from standard weakly-coupled mean-field theory. Spectroscopic
imaging confirms the presence of CDW, with LDOS maxima at the conduction band
corresponding to the LDOS minima at the valence band, thus revealing a {\pi}
phase difference in the respective CDW order. Concomitantly, at a monolayer
step edge, we detect an in-gap boundary mode with modulations along the edge
that match the CDW wavevector along the edge. Intriguingly, the phase of the
edge state modulation shifts by {\pi} within the charge order gap, connecting
the fully gapped bulk (and surface) conduction and valence bands via a smooth
energy-phase relation. This bears similarity to the topological spectral flow
of edge modes, where the boundary modes bridge the gapped bulk modes in energy
and momentum magnitude but in Ta2Se8I, the connectivity distinctly occurs in
energy and momentum phase. Notably, our temperature-dependent measurements
indicate a vanishing of the insulating gap and the in-gap edge state above
TCDW, suggesting their direct relation to CDW. The theoretical analysis also
indicates that the observed boundary mode is topological and linked to CDW.
The probe-particle model is an open-source package designed for simulation of
scanning probe microscopy experiments, employing non-reactive, flexible tip
apices (e.g., carbon monoxide, xenon, or hydrogen molecules) to achieve
sub-molecular resolution. This abstract introduces the latest version of the
probe-particle model, highlighting substantial advancements in accuracy,
computational performance, and user-friendliness over previous versions. To
demonstrate this we provide a comprehensive review of theories for simulating
non-contact Atomic Force Microscopy (nc-AFM), spanning from the simple
Lennard-Jones potential to the latest full density-based model. Implementation
of these theories are systematically compared against ab initio calculated
reference, showcasing their respective merits. All parts of the probe-particle
model have undergone acceleration by 1-2 orders of magnitude through
parallelization by OpenMP on CPU and OpenCL on GPU. The updated package
includes an interactive graphical user interface (GUI) and seamless integration
into the Python ecosystem via pip, facilitating advanced scripting and
interoperability with other software. This adaptability positions the
probe-particle model as an ideal tool for high-throughput applications,
including the training of machine learning models for the automatic recovery of
atomic structures from nc-AFM measurements. We envision significant potential
for this application in future single-molecule analysis, synthesis, and
advancements of surface science in general. Additionally, we discuss
simulations of other sub-molecular scanning-probe imaging techniques, such as
bond-resolved scanning tunneling microscopy and kelvin probe force microscopy,
all built on the robust foundation of the probe-particle model. Altogether this
demonstrates the broad impact of the model across diverse domains of surface
science and molecular chemistry.
The electronic states and topological properties of the biphenylene network
(BPN) are analyzed using a tight-binding model based on the $\pi$-electron
network. It is shown that tuning the hopping parameters induces topological
phase transitions, leading to the emergence of edge states owing to the
nontrivial topological Zak phase of the bulk BPN. Elementary band analysis
clearly gives the number of edge states, which are associated with the location
of Wannier centers. In addition, we have presented the conditions for the
emergence of corner states owing to the higher-order topological nature of BPN.
We present results of a Raman scattering study of the Kagome ferromagnet
Co$_3$Sn$_2$S$_2$, with a focus on electronic and phononic excitations and
their interplay. In addition, the electronic band structure is analyzed
theoretically, enabling a semi-quantitative explanation of the spectra. A
prominent feature in the electronic spectra is a redistribution of spectral
weight from low to high energies starting at the Curie temperature Tc. The
Raman intensity is suppressed below approximately 1000cm$^{-1}$ and increases
above to a peak at 2000 cm$^{-1}$ in all symmetries. Two Raman active phonon
modes are identified in A$_{1g}$ and E$_g$ symmetry. The A$_{1g}$ phonon
couples strongly to the electronic continuum as indicated by the asymmetric
Fano-type line shape. The asymmetry depends non-monotonically on temperature
and is maximal close to the magnetic transition. In the limit $T\to 0$ the
phonon is nearly symmetric. The evolution of the coupling strength and the
electronic continuum as a function of temperature is attributed to a band
splitting induced by the ferromagnetic phase transition which substantially
reduces the DOS towards $T=0$. The $3d_{z^2}$ electrons of the Co atoms in the
crystal field modulated by the A$_{1g}$ phonon are implied to be a critical
component contributing to the strong electron-phonon coupling of that phonon.
These results allow a comprehensive understanding of the bulk band structure
evolution as a function of temperature in Co$_3$Sn$_2$S$_2$, offering key
insights for further studies of the driving force behind the long-range
magnetic order and novel topological states in this compound.
The evolution of dynamic processes in graphene-family materials are of great
interest for both scientific purposes and technical applications. Scanning
electron microscopy and transmission electron microscopy outstand among the
techniques that allow both observing and controlling such dynamic processes in
real time. On the other hand, functionalized graphene oxide emerges as a
favorable candidate from graphene-family materials for such an investigation
due to its distinctive properties, that encompass a large surface area, robust
thermal stability, and noteworthy electrical and mechanical properties after
its reduction. Here, we report on studies of surface structure and adsorption
dynamics of L-Cysteine on electrochemically exfoliated graphene oxides basal
plane. We show that electron beam irradiation prompts an amorphization of
functionalized graphene oxide along with the formation of micropatterns of
controlled geometry composed of L-Cysteine-Graphene oxide nanostructures. The
controlled growth and predetermined arrangement of micropatterns as well as
controlled structure disorder induced by e beam amorphization, in its turn
potentially offering tailored properties and functionalities paving the way for
potential applications in nanotechnology, sensor development, and surface
engineering. Our findings demonstrate that graphene oxide can cover L-Cysteine
in such a way to provide a control on the positioning of emerging
microstructures about 10-20 um in diameter. Besides, Raman and SAED measurement
analyses yield above 50% amorphization in a material. The results of our
studies demonstrate that such a technique enables the direct creation of
micropatterns of L-Cysteine-Graphene oxide eliminating the need for complicated
mask patterning procedures.
In crystalline systems, higher-order topology, characterized by topological
states of codimension greater than one, typically arises from the mismatch
between Wannier centers and atomic sites, leading to filling anomalies.
However, this phenomenon is less understood in aperiodic systems, such as
quasicrystals, where Wannier centers are not well defined. In this study, we
examine Fibonacci chains and squares, a quintessential type of quasicrystal, to
investigate their higher-order topological properties. We discover that
topological interfacial states, including corner states, can be inherited from
their higher-dimensional periodic counterparts, such as the two-dimensional
Su-Schrieffer-Heeger model. This finding is validated through numerical
simulations of both phononic and photonic Fibonacci quasicrystals by the finite
element method, revealing the emergence of topological edge and corner states
at interfaces between Fibonacci quasicrystals with differing topologies
inherited from their parent systems. Our results not only provide insight into
the higher-order topology of quasicrystals but also open avenues for exploring
novel topological phases in aperiodic structures.
Using scanning tunneling microscopy (STM), we experimentally and
theoretically investigate isolated platinum phthalocyanine (PtPc) molecules
adsorbed on atomically thin NaCl(100) vapor deposited on Au(111). We obtain
good agreement between theory and constant-height STM topography. We examine
why strong distortions of STM images occur as a function of distance between
molecule and STM tip. The images of the highest occupied molecular orbital
(HOMO) and the lowest unoccupied molecular orbital (LUMO) exhibit, for
increasing distance, significant radial expansion due to electron propagation
in the vacuum. Additionally, the imaged angular dependence is substantially
distorted. The LUMO image has substantial intensity along the molecular
diagonals where PtPc has no atoms. In the electronic transport gap the image
differs drastically from HOMO and LUMO, even at energies very close to these
orbitals. As the tunneling becomes increasingly off-resonant, the eight angular
lobes of the HOMO or of the degenerate LUMOs diminish and reveal four lobes
with maxima along the molecular axes, where both, HOMO and LUMO have little or
no weight. These images are strongly influenced by low-lying PtPc orbitals that
have simple angular structures.
We present the Python-based Molecule Builder for ESPResSo (pyMBE), an open
source software designed to build coarse-grained models of polyelectrolytes,
peptides and globular proteins of arbitrary topology into the Extensible
Simulation Package for Research on Soft Matter (ESPResSo). ESPResSo features
the constant pH (cpH) and grand-reaction (G-RxMC) methods, which are powerful
tools to study macromolecular systems with many reactive groups, permitting to
efficiently sample systems with multiple coupled chemical equilibria. However,
setting up these methods for macromolecules with many different reactive groups
is a non-trivial and error-prone task, especially for beginners. pyMBE enables
the automatic setup of cpH and G-RxMC simulations in ESPResSo, lowering the
barrier for newcomers and opening the door to investigate complex systems not
yet studied with these methods. To demonstrate some of the applications of
pyMBE, we showcase several study cases where pyMBE successfully reproduces
previous simulations in the literature done with ESPResSo and other software,
including various simulations of different peptides in bulk solution,
simulations of weak polyelectrolytes in dialysis and simulations of globular
proteins in bulk solution. pyMBE is publicly available as a GitLab repository
(https://gitlab.com/blancoapa/pyMBE) which includes its source code and various
sample and test scripts, including the ones that we used to generated the data
presented in this article.
This study presents Fermi-arcs mediated transport in a Weyl semimetal thin
slab, interfacing two $s$-wave superconductors. We present detailed study with
both time-reversal and inversion symmetry broken Weyl semimetals under
grounding, orbital magnetic fields, and Zeeman fields. An orbital magnetic
field induces energy level oscillations, while a Zeeman field give rise to the
periodic anomalous oscillations in the Josephson current. These anomalous
oscillations correlate with the separation of Weyl nodes in momentum space,
junction length, and system symmetries. Additionally, we present an explanation
by scattering theory modeling the Fermi-arcs as a network model.
The chiral lattice structure of twisted bilayer graphene with D6 symmetry
allows for intrinsic photogalvanic effects only at off-normal incidence, while
additional extrinsic effects are known to be induced by a substrate or a gate
potential. In this work, we first compute the intrinsic effects and show they
reverse sign at the magic angle, revealing a band inversion at the {\Gamma}
point. We next consider different extrinsic effects, showing how they can be
used to track the strengths of the substrate coupling or displacement field. We
also show that the approximate particle-hole symmetry implies stringent
constraints on the chemical potential dependence of all photocurrents. A
detailed comparison of intrinsic vs. extrinsic photocurrents therefore reveals
a wealth of information about the band structure and can also serve as a
benchmark to constrain the symmetry breaking patterns of correlated states.
Certifying quantum entanglement is a critical step towards realizing
quantum-coherent applications of surface spin systems. In this work, we show
that entanglement can be unambiguously shown in a scanning tunneling microscope
(STM) with electron spin resonance by exploiting the fact that entangled states
undergo a free time evolution with a distinct characteristic time constant that
clearly distinguishes it from any other time evolution in the system. By
implementing a suitable phase control scheme, the phase of this time evolution
can be mapped back onto the population of one entangled spin in a pair, which
can then be read out reliably using a weakly coupled sensor spin in the
junction of the scanning tunneling microscope. We demonstrate through open
quantum system simulations with realistic spin systems, which are currently
available with spin coherence times of $T_2\approx$ 300 ns, that a signal
directly correlated with the degree of entanglement can be measured at a
temperature range of 100$-$400 mK accessible in sub-Kelvin cryogenic STM
systems.
Coupled oscillator networks provide mathematical models for interacting
periodic processes. If the coupling is weak, phase reduction -- the reduction
of the dynamics onto an invariant torus -- captures the emergence of collective
dynamical phenomena, such as synchronization. While a first-order approximation
of the dynamics on the torus may be appropriate in some situations,
higher-order phase reductions become necessary, for example, when the coupling
strength increases. However, these are generally hard to compute and thus they
have only been derived in special cases: This includes globally coupled
Stuart--Landau oscillators, where the limit cycle of the uncoupled nonlinear
oscillator is circular as the amplitude is independent of the phase. We go
beyond this restriction and derive second-order phase reductions for coupled
oscillators for arbitrary networks of coupled nonlinear oscillators with
phase-dependent amplitude, a scenario more reminiscent of real-world
oscillations. We analyze how the deformation of the limit cycle affects the
stability of important dynamical states, such as full synchrony and splay
states. By identifying higher-order phase interaction terms with hyperedges of
a hypergraph, we obtain natural classes of coupled phase oscillator dynamics on
hypergraphs that adequately capture the dynamics of coupled limit cycle
oscillators.
Lieb-Schultz-Mattis (LSM) theorems impose non-perturbative constraints on the
zero-temperature phase diagrams of quantum lattice Hamiltonians (always assumed
to be local in this paper). LSM theorems have recently been interpreted as the
lattice counterparts to mixed 't Hooft anomalies in quantum field theories that
arise from a combination of crystalline and global internal symmetry groups.
Accordingly, LSM theorems have been reinterpreted as LSM anomalies. In this
work, we provide a systematic diagnostic for LSM anomalies in one spatial
dimension. We show that gauging subgroups of the global internal symmetry group
of a quantum lattice model obeying an LSM anomaly delivers a dual quantum
lattice Hamiltonian such that its internal and crystalline symmetries mix
non-trivially through a group extension. This mixing of crystalline and
internal symmetries after gauging is a direct consequence of the LSM anomaly,
i.e., it can be used as a diagnostic of an LSM anomaly. We exemplify this
procedure for a quantum spin-1/2 chain obeying an LSM anomaly resulting from
combining a global internal $\mathbb{Z}^{\,}_{2}\times\mathbb{Z}^{\,}_{2}$
symmetry with translation or reflection symmetry. We establish a triality of
models by gauging a
$\mathbb{Z}^{\,}_{2}\subset\mathbb{Z}^{\,}_{2}\times\mathbb{Z}^{\,}_{2}$
symmetry in two ways, one of which amounts to performing a Kramers-Wannier
duality, while the other implements a Jordan-Wigner duality. We discuss the
mapping of the phase diagram of the quantum spin-1/2 $XYZ$ chains under such a
triality. We show that the deconfined quantum critical transitions between Neel
and dimer orders are mapped to either topological or conventional
Landau-Ginzburg transitions. Finally, we extend our results to
$\mathbb{Z}^{\,}_{n}$ clock models and provide a reinterpretation of the dual
internal symmetries in terms of $\mathbb{Z}^{\,}_{n}$ charge and dipole
symmetries.
We investigate anomalous localization phenomena in non-Hermitian systems by
solving a class of generalized Su-Schrieffer-Heeger/Rice-Mele models and by
relating their provenance to fundamental notions of topology, symmetry-breaking
and biorthogonality. We find two flavours of bound states in the continuum,
both stable even in the absence of chiral symmetry. The first being skin bulk
states which are protected by the spectral winding number. The second flavour
is constituted by boundary modes associated with a quantized biorthogonal
polarization. Furthermore, we find the extended state stemming from the
boundary state that delocalizes while remaining in the gap at bulk critical
points. This state may also delocalize within a continuum of localized (skin)
states. These results clarify fundamental aspects of topology, and symmetry in
the light of different approaches to the anomalous non-Hermitan bulk-boundary
correspondence -- and are of direct experimental relevance for mechanical,
electrical and photonic systems.
Numerical analysis of conserved field dynamics has been generally performed
with pseudo spectral methods. Finite differences integration, the common
procedure for non-conserved field dynamics, indeed struggles to implement a
conservative noise in the discrete spatial domain. In this work, we present a
novel method to generate a conservative noise in the finite differences
framework, which works for any discrete topology and boundary conditions. We
apply it to numerically solve the conserved Kardar-Parisi-Zhang (cKPZ)
equation, widely used to describe surface roughening when the number of
particles is conserved. Our numerical simulations recover the correct scaling
exponents $\alpha$, $\beta$, and $z$ in $d=1$ and in $d=2$. To illustrate the
potentiality of the method, we further consider the cKPZ equation on different
kinds of non-standard lattices and on the random Euclidean graph. This is the
first numerical study of conserved field dynamics on an irregular topology,
paving the way to a broad spectrum of possible applications.
We discuss the derivation of the electrodynamics of superconductors coupled
to the electromagnetic field from a Lorentz-invariant bosonic model of Cooper
pairs. Our results are obtained at zero temperature where, according to the
third law of thermodynamics, the entropy of the system is zero. In the
nonrelativistic limit we obtain a Galilei-invariant superconducting system
which differs with respect to the familiar Schr\"odinger-like one. From this
point of view, there are similarities with the Pauli equation of fermions which
is derived from the Dirac equation in the nonrelativistic limit and has a
spin-magnetic field term in contrast with the Schr\"odinger equation. One of
the peculiar effects of our model is the decay of a static electric field
inside a superconductor exactly with the London penetration length. In
addition, our theory predicts a modified D'Alembert equation for the massive
electromagnetic field also in the case of nonrelativistic superconducting
matter. We emphasize the role of the Nambu-Goldstone phase field which is
crucial to obtain the collective modes of the superconducting matter field. In
the special case of a nonrelativistic neutral superfluid we find a gapless
Bogoliubov-like spectrum, while for the charged superfluid we obtain a
dispersion relation that is gapped by the plasma frequency.
