text: We demonstrate the formation of robust zero-energy modes close to magnetic
impurities in the iron-based superconductor FeSe1-z Tez. We find that the Zeeman
field generated by the impurity favors a spin-triplet interorbital pairing as
opposed to the spin-singlet intraorbital pairing prevalent in the bulk. The preferred
spin-triplet pairing preserves time-reversal symmetry and is topological, as robust,
topologically protected zero modes emerge at the boundary between regions with
different pairing states. Moreover, the zero modes form Kramers doublets that
are insensitive to the direction of the spin polarization or to the separation
between impurities. We argue that our theoretical results are consistent with
recent experimental measurements on FeSe1-z Tez.

text: The search for novel entangled phases of matter has lead to the recent discovery
of a new class of “entanglement transitions,” exemplified by random tensor networks
and monitored quantum circuits. Most known examples can be understood as some
classical ordering transitions in an underlying statistical mechanics model, where
entanglement maps onto the free-energy cost of inserting a domain wall. In this
paper we study the possibility of entanglement transitions driven by physics beyond
such statistical mechanics mappings. Motivated by recent applications of neural-network-inspired
variational Ansätze, we investigate under what conditions on the variational parameters
these Ansätze can capture an entanglement transition. We study the entanglement
scaling of short-range restricted Boltzmann machine (RBM) quantum states with
random phases. For uncorrelated random phases, we analytically demonstrate the
absence of an entanglement transition and reveal subtle finite-size effects in
finite-size numerical simulations. Introducing phases with correlations decaying
as 1/r^α in real space, we observe three regions with a different scaling of entanglement
entropy depending on the exponent α. We study the nature of the transition between
these regions, finding numerical evidence for critical behavior. Our work establishes
the presence of long-range correlated phases in RBM-based wave functions as a
required ingredient for entanglement transitions.

text: Harnessing the properties of vortices in superconductors is crucial for fundamental
science and technological applications; thus, it has been an ongoing goal to locally
probe and control vortices. Here, we use a scanning probe technique that enables
studies of vortex dynamics in superconducting systems by leveraging the resonant
behavior of a raster-scanned, magnetic-tipped cantilever. This experimental setup
allows us to image and control vortices, as well as extract key energy scales
of the vortex interactions. Applying this technique to lattices of superconductor
island arrays on a metal, we obtain a variety of striking spatial patterns that
encode information about the energy landscape for vortices in the system. We interpret
these patterns in terms of local vortex dynamics and extract the relative strengths
of the characteristic energy scales in the system, such as the vortex-magnetic
field and vortex-vortex interaction strengths, as well as the vortex chemical
potential. We also demonstrate that the relative strengths of the interactions
can be tuned and show how these interactions shift with an applied bias. The high
degree of tunability and local nature of such vortex imaging and control not only
enable new understanding of vortex interactions, but also have potential applications
in more complex systems such as those relevant to quantum computing.

text: We study an effective one-dimensional quantum model that includes friction
and spin-orbit coupling (SOC), and show that the model exhibits spin polarization
when both terms are finite. Most important, strong spin polarization can be observed
even for moderate SOC, provided that the friction is strong. Our findings might
help to explain the pronounced effect of chirality on spin distribution and transport
in chiral molecules. In particular, our model implies static magnetic properties
of a chiral molecule, which lead to Shiba-like states when a molecule is placed
on a superconductor, in accordance with recent experimental data.

text: The notion of Thouless energy plays a central role in the theory of Anderson
localization. We investigate and compare the scaling of Thouless energy across
the many-body localization (MBL) transition in a Floquet model. We use a combination
of methods that are reliable on the ergodic side of the transition (e.g., spectral
form factor) and methods that work on the MBL side (e.g., typical matrix elements
of local operators) to obtain a complete picture of the Thouless energy behavior
across the transition. On the ergodic side, Thouless energy decreases slowly with
the system size, while at the transition it becomes comparable to the level spacing.
Different probes yield consistent estimates of Thouless energy in their overlapping
regime of applicability, giving the location of the transition point nearly free
of finite-size drift. This work establishes a connection between different definitions
of Thouless energy in a many-body setting and yields insights into the MBL transition
in Floquet systems.

text: 'Many-body localization provides a mechanism to avoid thermalization in isolated
interacting quantum systems. The breakdown of thermalization may be complete,
when all eigenstates in the many-body spectrum become localized, or partial, when
the so-called many-body mobility edge separates localized and delocalized parts
of the spectrum. Previously, De Roeck et al. [Phys. Rev. B 93, 014203 (2016)]
suggested a possible instability of the many-body mobility edge in energy density.
The local ergodic regions—so-called “bubbles”—resonantly spread throughout the
system, leading to delocalization. In order to study such instability mechanism,
in this work we design a model featuring many-body mobility edge in particle density:
the states at small particle density are localized, while increasing the density
of particles leads to delocalization. Using numerical simulations with matrix
product states, we demonstrate the stability of many-body localization with respect
to small bubbles in large dilute systems for experimentally relevant timescales.
In addition, we demonstrate that processes where the bubble spreads are favored
over processes that lead to resonant tunneling, suggesting a possible mechanism
behind the observed stability of many-body mobility edge. We conclude by proposing
experiments to probe particle density mobility edge in the Bose-Hubbard model.'

text: Dipolar (or spatially indirect) excitons (IXs) in semiconductor double quantum
well (DQW) subjected to an electric field are neutral species with a dipole moment
oriented perpendicular to the DQW plane. Here, we theoretically study interactions
between IXs in stacked DQW bilayers, where the dipolar coupling can be either
attractive or repulsive depending on the relative positions of the particles.
By using microscopic band structure calculations to determine the electronic states
forming the excitons, we show that the attractive dipolar interaction between
stacked IXs deforms their electronic wave function, thereby increasing the inter-DQW
interaction energy and making the IX even more electrically polarizable. Many-particle
interaction effects are addressed by considering the coupling between a single
IX in one of the DQWs to a cloud of IXs in the other DQW, which is modeled either
as a closed-packed lattice or as a continuum IX fluid. We find that the lattice
model yields IX interlayer binding energies decreasing with increasing lattice
density. This behavior is due to the dominating role of the intra-DQW dipolar
repulsion, which prevents more than one exciton from entering the attractive region
of the inter-DQW coupling. Finally, both models shows that the single IX distorts
the distribution of IXs in the adjacent DQW, thus inducing the formation of an
IX dipolar polaron (dipolaron). While the interlayer binding energy reduces with
IX density for lattice dipolarons, the continuous polaron model predicts a nonmonotonous
dependence on density in semiquantitative agreement with a recent experimental
study [cf. Hubert et al., Phys. Rev. X 9, 021026 (2019)].

text: One of the hallmarks of quantum statistics, tightly entwined with the concept
of topological phases of matter, is the prediction of anyons. Although anyons
are predicted to be realized in certain fractional quantum Hall systems, they
have not yet been unambiguously detected in experiment. Here we introduce a simple
quantum impurity model, where bosonic or fermionic impurities turn into anyons
as a consequence of their interaction with the surrounding many-particle bath.
A cloud of phonons dresses each impurity in such a way that it effectively attaches
fluxes or vortices to it and thereby converts it into an Abelian anyon. The corresponding
quantum impurity model, first, provides a different approach to the numerical
solution of the many-anyon problem, along with a concrete perspective of anyons
as emergent quasiparticles built from composite bosons or fermions. More importantly,
the model paves the way toward realizing anyons using impurities in crystal lattices
as well as ultracold gases. In particular, we consider two heavy electrons interacting
with a two-dimensional lattice crystal in a magnetic field, and show that when
the impurity-bath system is rotated at the cyclotron frequency, impurities behave
as anyons as a consequence of the angular momentum exchange between the impurities
and the bath. A possible experimental realization is proposed by identifying the
statistics parameter in terms of the mean-square distance of the impurities and
the magnetization of the impurity-bath system, both of which are accessible to
experiment. Another proposed application is impurities immersed in a two-dimensional
weakly interacting Bose gas.

text: Multilayer graphene lattices allow for an additional tunability of the band
structure by the strong perpendicular electric field. In particular, the emergence
of the new multiple Dirac points in ABA stacked trilayer graphene subject to strong
transverse electric fields was proposed theoretically and confirmed experimentally.
These new Dirac points dubbed “gullies” emerge from the interplay between strong
electric field and trigonal warping. In this work, we first characterize the properties
of new emergent Dirac points and show that the electric field can be used to tune
the distance between gullies in the momentum space. We demonstrate that the band
structure has multiple Lifshitz transitions and higher-order singularity of “monkey
saddle” type. Following the characterization of the band structure, we consider
the spectrum of Landau levels and structure of their wave functions. In the limit
of strong electric fields when gullies are well separated in momentum space, they
give rise to triply degenerate Landau levels. In the second part of this work,
we investigate how degeneracy between three gully Landau levels is lifted in the
presence of interactions. Within the Hartree-Fock approximation we show that the
symmetry breaking state interpolates between the fully gully polarized state that
breaks C3 symmetry at high displacement field and the gully symmetric state when
the electric field is decreased. The discontinuous transition between these two
states is driven by enhanced intergully tunneling and exchange. We conclude by
outlining specific experimental predictions for the existence of such a symmetry-breaking
state.

text: Chains of superconducting circuit devices provide a natural platform for studies
of synthetic bosonic quantum matter. Motivated by the recent experimental progress
in realizing disordered and interacting chains of superconducting transmon devices,
we study the bosonic many-body localization phase transition using the methods
of exact diagonalization as well as matrix product state dynamics. We estimate
the location of transition separating the ergodic and the many-body localized
phases as a function of the disorder strength and the many-body on-site interaction
strength. The main difference between the bosonic model realized by superconducting
circuits and similar fermionic model is that the effect of the on-site interaction
is stronger due to the possibility of multiple excitations occupying the same
site. The phase transition is found to be robust upon including longer-range hopping
and interaction terms present in the experiments. Furthermore, we calculate experimentally
relevant local observables and show that their temporal fluctuations can be used
to distinguish between the dynamics of Anderson insulator, many-body localization,
and delocalized phases. While we consider unitary dynamics, neglecting the effects
of dissipation, decoherence, and measurement back action, the timescales on which
the dynamics is unitary are sufficient for observation of characteristic dynamics
in the many-body localized phase. Moreover, the experimentally available disorder
strength and interactions allow for tuning the many-body localization phase transition,
thus making the arrays of superconducting circuit devices a promising platform
for exploring localization physics and phase transition.

text: We modify the "floating crystal" trial state for the classical homogeneous
electron gas (also known as jellium), in order to suppress the boundary charge
fluctuations that are known to lead to a macroscopic increase of the energy. The
argument is to melt a thin layer of the crystal close to the boundary and consequently
replace it by an incompressible fluid. With the aid of this trial state we show
that three different definitions of the ground-state energy of jellium coincide.
In the first point of view the electrons are placed in a neutralizing uniform
background. In the second definition there is no background but the electrons
are submitted to the constraint that their density is constant, as is appropriate
in density functional theory. Finally, in the third system each electron interacts
with a periodic image of itself; that is, periodic boundary conditions are imposed
on the interaction potential.

text: End-to-end correlated bound states are investigated in superconductor-semiconductor
hybrid nanowires at zero magnetic field. Peaks in subgap conductance are independently
identified from each wire end, and a cross-correlation function is computed that
counts end-to-end coincidences, averaging over thousands of subgap features. Strong
correlations in a short, 300-nm device are reduced by a factor of 4 in a long,
900-nm device. In addition, subgap conductance distributions are investigated,
and correlations between the left and right distributions are identified based
on their mutual information.

text: Recent scanning tunneling microscopy experiments in NbN thin disordered superconducting
films found an emergent inhomogeneity at the scale of tens of nanometers. This
inhomogeneity is mirrored by an apparent dimensional crossover in the paraconductivity
measured in transport above the superconducting critical temperature Tc. This
behavior was interpreted in terms of an anomalous diffusion of fluctuating Cooper
pairs that display a quasiconfinement (i.e., a slowing down of their diffusive
dynamics) on length scales shorter than the inhomogeneity identified by tunneling
experiments. Here, we assume this anomalous diffusive behavior of fluctuating
Cooper pairs and calculate the effect of these fluctuations on the electron density
of states above Tc. We find that the density of states is substantially suppressed
up to temperatures well above Tc. This behavior, which is closely reminiscent
of a pseudogap, only arises from the anomalous diffusion of fluctuating Cooper
pairs in the absence of stable preformed pairs, setting the stage for an intermediate
behavior between the two common paradigms in the superconducting-insulator transition,
namely, the localization of Cooper pairs (the so-called bosonic scenario) and
the breaking of Cooper pairs into unpaired electrons due to strong disorder (the
so-called fermionic scenario).

text: We propose a scaling theory for the many-body localization (MBL) phase transition
in one dimension, building on the idea that it proceeds via a “quantum avalanche.”
We argue that the critical properties can be captured at a coarse-grained level
by a Kosterlitz-Thouless (KT) renormalization group (RG) flow. On phenomenological
grounds, we identify the scaling variables as the density of thermal regions and
the length scale that controls the decay of typical matrix elements. Within this
KT picture, the MBL phase is a line of fixed points that terminates at the delocalization
transition. We discuss two possible scenarios distinguished by the distribution
of rare, fractal thermal inclusions within the MBL phase. In the first scenario,
these regions have a stretched exponential distribution in the MBL phase. In the
second scenario, the near-critical MBL phase hosts rare thermal regions that are
power-law-distributed in size. This points to the existence of a second transition
within the MBL phase, at which these power laws change to the stretched exponential
form expected at strong disorder. We numerically simulate two different phenomenological
RGs previously proposed to describe the MBL transition. Both RGs display a universal
power-law length distribution of thermal regions at the transition with a critical
exponent αc=2, and continuously varying exponents in the MBL phase consistent
with the KT picture.

text: We examine recent magnetic torque measurements in two compounds, γ−Li2IrO3
and RuCl3, which have been discussed as possible realizations of the Kitaev model.
The analysis of the reported discontinuity in torque, as an external magnetic
field is rotated across the c axis in both crystals, suggests that they have a
translationally invariant chiral spin order of the form ⟨Si⋅(Sj×Sk)⟩≠0 in the
ground state and persisting over a very wide range of magnetic field and temperature.
An extraordinary |B|B2 dependence of the torque for small fields, beside the usual
B2 part, is predicted by the chiral spin order. Data for small fields are available
for γ−Li2IrO3 and are found to be consistent with the prediction upon further
analysis. Other experiments such as inelastic scattering and thermal Hall effect
and several questions raised by the discovery of chiral spin order, including
its topological consequences, are discussed.

text: We study a quantum impurity possessing both translational and internal rotational
degrees of freedom interacting with a bosonic bath. Such a system corresponds
to a “rotating polaron,” which can be used to model, e.g., a rotating molecule
immersed in an ultracold Bose gas or superfluid helium. We derive the Hamiltonian
of the rotating polaron and study its spectrum in the weak- and strong-coupling
regimes using a combination of variational, diagrammatic, and mean-field approaches.
We reveal how the coupling between linear and angular momenta affects stable quasiparticle
states, and demonstrate that internal rotation leads to an enhanced self-localization
in the translational degrees of freedom.

text: We construct a metamaterial from radio-frequency harmonic oscillators, and
find two topologically distinct phases resulting from dissipation engineered into
the system. These phases are distinguished by a quantized value of bulk energy
transport. The impulse response of our circuit is measured and used to reconstruct
the band structure and winding number of circuit eigenfunctions around a dark
mode. Our results demonstrate that dissipative topological transport can occur
in a wider class of physical systems than considered before.

text: We present a scanning probe technique for measuring the dynamics of individual
fluxoid transitions in multiply connected superconducting structures. In these
measurements, a small magnetic particle attached to the tip of a silicon cantilever
is scanned over a micron-size superconducting ring fabricated from a thin aluminum
film. We find that near the superconducting transition temperature of the aluminum,
the dissipation and frequency of the cantilever changes significantly at particular
locations where the tip-induced magnetic flux penetrating the ring causes the
two lowest-energy fluxoid states to become nearly degenerate. In this regime,
we show that changes in the cantilever frequency and dissipation are well-described
by a stochastic resonance (SR) process, wherein small oscillations of the cantilever
in the presence of thermally activated phase slips (TAPS) in the ring give rise
to a dynamical force that modifies the mechanical properties of the cantilever.
Using the SR model, we calculate the average fluctuation rate of the TAPS as a
function of temperature over a 32-dB range in frequency, and we compare it to
the Langer-Ambegaokar-McCumber-Halperin theory for TAPS in one-dimensional superconducting
structures.

text: The Gibbs free energy is the fundamental thermodynamic potential underlying
the relative stability of different states of matter under constant-pressure conditions.
However, computing this quantity from atomic-scale simulations is far from trivial,
so the potential energy of a system is often used as a proxy. In this paper, we
use a combination of thermodynamic integration methods to accurately evaluate
the Gibbs free energies associated with defects in crystals, including the vacancy
formation energy in bcc iron, and the stacking fault energy in fcc nickel, iron,
and cobalt. We quantify the importance of entropic and anharmonic effects in determining
the free energies of defects at high temperatures, and show that the potential
energy approximation as well as the harmonic approximation may produce inaccurate
or even qualitatively wrong results. Our calculations manifest the necessity to
employ accurate free energy methods such as thermodynamic integration to estimate
the stability of crystallographic defects at high temperatures.

text: Magnetic anisotropy in strontium iridate (Sr2IrO4) is found to be large because
of the strong spin-orbit interactions. In our work, we studied the in-plane magnetic
anisotropy of Sr2IrO4 and traced the anisotropic exchange interactions between
the isospins in the crystal. The magnetic-field-dependent torque τ(H) showed a
prominent transition from the canted antiferromagnetic state to the weak ferromagnetic
(WFM) state. A comprehensive analysis was conducted to examine the isotropic and
anisotropic regimes and probe the easy magnetization axis along the a b plane.
The angle-dependent torque τ(θ) revealed a deviation from the sinusoidal behavior,
and small differences in hysteresis were observed around 0° and 90° in the low-magnetic-field
regime. This indicates that the orientation of the easy axis of the FM component
is along the b axis, where the antiferromagnetic to WFM spin-flop transition occurs.
We compared the coefficients of the magnetic susceptibility tensors and captured
the anisotropy of the material. The in-plane τ(θ) revealed a tendency toward isotropic
