text: 'Motivated by properties-controlling potential of the strain, we investigate
strain dependence of structure, electronic, and magnetic properties of Sr2IrO4
using complementary theoretical tools: ab-initio calculations, analytical approaches
(rigid octahedra picture, Slater-Koster integrals), and extended t−J model. We
find that strain affects both Ir-Ir distance and Ir-O-Ir angle, and the rigid
octahedra picture is not relevant. Second, we find fundamentally different behavior
for compressive and tensile strain. One remarkable feature is the formation of
two subsets of bond- and orbital-dependent carriers, a compass-like model, under
compression. This originates from the strain-induced renormalization of the Ir-O-Ir
superexchange and O on-site energy. We also show that under compressive (tensile)
strain, Fermi surface becomes highly dispersive (relatively flat). Already at
a tensile strain of 1.5%, we observe spectral weight redistribution, with the
low-energy band acquiring almost purely singlet character. These results can be
directly compared with future experiments.'

text: Methods inspired from machine learning have recently attracted great interest
in the computational study of quantum many-particle systems. So far, however,
it has proven challenging to deal with microscopic models in which the total number
of particles is not conserved. To address this issue, we propose a new variant
of neural network states, which we term neural coherent states. Taking the Fröhlich
impurity model as a case study, we show that neural coherent states can learn
the ground state of non-additive systems very well. In particular, we observe
substantial improvement over the standard coherent state estimates in the most
challenging intermediate coupling regime. Our approach is generic and does not
assume specific details of the system, suggesting wide applications.

text: Area-dependent quantum field theory is a modification of two-dimensional topological
quantum field theory, where one equips each connected component of a bordism with
a positive real number—interpreted as area—which behaves additively under glueing.
As opposed to topological theories, in area-dependent theories the state spaces
can be infinite-dimensional. We introduce the notion of regularised Frobenius
algebras in Hilbert spaces and show that area-dependent theories are in one-to-one
correspondence to commutative regularised Frobenius algebras. We also provide
a state sum construction for area-dependent theories. Our main example is two-dimensional
Yang–Mills theory with compact gauge group, which we treat in detail.

text: Studies on the experimental realization of two-dimensional anyons in terms
of quasiparticles have been restricted, so far, to only anyons on the plane. It
is known, however, that the geometry and topology of space can have significant
effects on quantum statistics for particles moving on it. Here, we have undertaken
the first step toward realizing the emerging fractional statistics for particles
restricted to move on the sphere instead of on the plane. We show that such a
model arises naturally in the context of quantum impurity problems. In particular,
we demonstrate a setup in which the lowest-energy spectrum of two linear bosonic
or fermionic molecules immersed in a quantum many-particle environment can coincide
with the anyonic spectrum on the sphere. This paves the way toward the experimental
realization of anyons on the sphere using molecular impurities. Furthermore, since
a change in the alignment of the molecules corresponds to the exchange of the
particles on the sphere, such a realization reveals a novel type of exclusion
principle for molecular impurities, which could also be of use as a powerful technique
to measure the statistics parameter. Finally, our approach opens up a simple numerical
route to investigate the spectra of many anyons on the sphere. Accordingly, we
present the spectrum of two anyons on the sphere in the presence of a Dirac monopole
field.

text: We employ the Gross-Pitaevskii equation to study acoustic emission generated
in a uniform Bose gas by a static impurity. The impurity excites a sound-wave
packet, which propagates through the gas. We calculate the shape of this wave
packet in the limit of long wave lengths, and argue that it is possible to extract
properties of the impurity by observing this shape. We illustrate here this possibility
for a Bose gas with a trapped impurity atom -- an example of a relevant experimental
setup. Presented results are general for all one-dimensional systems described
by the nonlinear Schrödinger equation and can also be used in nonatomic systems,
e.g., to analyze light propagation in nonlinear optical media. Finally, we calculate
the shape of the sound-wave packet for a three-dimensional Bose gas assuming a
spherically symmetric perturbation.

text: Sound propagation is a macroscopic manifestation of the interplay between
the equilibrium thermodynamics and the dynamical transport properties of fluids.
Here, for a two-dimensional system of ultracold fermions, we calculate the first
and second sound velocities across the whole BCS-BEC crossover, and we analyze
the system response to an external perturbation. In the low-temperature regime
we reproduce the recent measurements [Phys. Rev. Lett. 124, 240403 (2020)] of
the first sound velocity, which, due to the decoupling of density and entropy
fluctuations, is the sole mode excited by a density probe. Conversely, a heat
perturbation excites only the second sound, which, being sensitive to the superfluid
depletion, vanishes in the deep BCS regime and jumps discontinuously to zero at
the Berezinskii-Kosterlitz-Thouless superfluid transition. A mixing between the
modes occurs only in the finite-temperature BEC regime, where our theory converges
to the purely bosonic results.

text: The relative motion of three impenetrable particles on a ring, in our case
two identical fermions and one impurity, is isomorphic to a triangular quantum
billiard. Depending on the ratio κ of the impurity and fermion masses, the billiards
can be integrable or non-integrable (also referred to in the main text as chaotic).
To set the stage, we first investigate the energy level distributions of the billiards
as a function of 1/κ ∈ [0, 1] and find no evidence of integrable cases beyond
the limiting values 1/κ = 1 and 1/κ = 0. Then, we use machine learning tools to
analyze properties of probability distributions of individual quantum states.
We find that convolutional neural networks can correctly classify integrable and
non-integrable states. The decisive features of the wave functions are the normalization
and a large number of zero elements, corresponding to the existence of a nodal
line. The network achieves typical accuracies of 97%, suggesting that machine
learning tools can be used to analyze and classify the morphology of probability
densities obtained in theory or experiment.

text: Ferromagnetism is most common in transition metal compounds but may also arise
in low-density two-dimensional electron systems, with signatures observed in silicon,
III-V semiconductor systems, and graphene moiré heterostructures. Here we show
that gate-tuned van Hove singularities in rhombohedral trilayer graphene drive
the spontaneous ferromagnetic polarization of the electron system into one or
more spin- and valley flavors. Using capacitance measurements on graphite-gated
van der Waals heterostructures, we find a cascade of density- and electronic displacement
field tuned phase transitions marked by negative electronic compressibility. The
transitions define the boundaries between phases where quantum oscillations have
either four-fold, two-fold, or one-fold degeneracy, associated with a spin and
valley degenerate normal metal, spin-polarized `half-metal', and spin and valley
polarized `quarter metal', respectively. For electron doping, the salient features
are well captured by a phenomenological Stoner model with a valley-anisotropic
Hund's coupling, likely arising from interactions at the lattice scale. For hole
filling, we observe a richer phase diagram featuring a delicate interplay of broken
symmetries and transitions in the Fermi surface topology. Finally, by rotational
alignment of a hexagonal boron nitride substrate to induce a moiré superlattice,
we find that the superlattice perturbs the preexisting isospin order only weakly,
leaving the basic phase diagram intact while catalyzing the formation of topologically
nontrivial gapped states whenever itinerant half- or quarter metal states occur
at half- or quarter superlattice band filling. Our results show that rhombohedral
trilayer graphene is an ideal platform for well-controlled tests of many-body
theory and reveal magnetism in moiré materials to be fundamentally itinerant in
nature.

text: Superconductor-semiconductor hybrids are platforms for realizing effective
p-wave superconductivity. Spin-orbit coupling, combined with the proximity effect,
causes the two-dimensional semiconductor to inherit p±ip intraband pairing, and
application of magnetic field can then result in transitions to the normal state,
partial Bogoliubov Fermi surfaces, or topological phases with Majorana modes.
Experimentally probing the hybrid superconductor-semiconductor interface is challenging
due to the shunting effect of the conventional superconductor. Consequently, the
nature of induced pairing remains an open question. Here, we use the circuit quantum
electrodynamics architecture to probe induced superconductivity in a two dimensional
Al-InAs hybrid system. We observe a strong suppression of superfluid density and
enhanced dissipation driven by magnetic field, which cannot be accounted for by
the depairing theory of an s-wave superconductor. These observations are explained
by a picture of independent intraband p±ip superconductors giving way to partial
Bogoliubov Fermi surfaces, and allow for the first characterization of key properties
of the hybrid superconducting system.

text: We investigate the effect of coupling between translational and internal degrees
of freedom of composite quantum particles on their localization in a random potential.
We show that entanglement between the two degrees of freedom weakens localization
due to the upper bound imposed on the inverse participation ratio by purity of
a quantum state. We perform numerical calculations for a two-particle system bound
by a harmonic force in a 1D disordered lattice and a rigid rotor in a 2D disordered
lattice. We illustrate that the coupling has a dramatic effect on localization
properties, even with a small number of internal states participating in quantum
dynamics.

text: "We give a combinatorial model for r-spin surfaces with parameterized boundary
based on Novak (“Lattice topological field theories in two dimensions,” Ph.D.
thesis, Universität Hamburg, 2015). The r-spin structure is encoded in terms of
ℤ\U0001D45F-valued indices assigned to the edges of a polygonal decomposition.
This combinatorial model is designed for our state-sum construction of two-dimensional
topological field theories on r-spin surfaces. We show that an example of such
a topological field theory computes the Arf-invariant of an r-spin surface as
introduced by Randal-Williams [J. Topol. 7, 155 (2014)] and Geiges et al. [Osaka
J. Math. 49, 449 (2012)]. This implies, in particular, that the r-spin Arf-invariant
is constant on orbits of the mapping class group, providing an alternative proof
of that fact."

text: Theoretical and experimental studies of the interaction between spins and
temperature are vital for the development of spin caloritronics, as they dictate
the design of future devices. In this work, we propose a two-terminal cold-atom
simulator to study that interaction. The proposed quantum simulator consists of
strongly interacting atoms that occupy two temperature reservoirs connected by
a one-dimensional link. First, we argue that the dynamics in the link can be described
using an inhomogeneous Heisenberg spin chain whose couplings are defined by the
local temperature. Second, we show the existence of a spin current in a system
with a temperature difference by studying the dynamics that follows the spin-flip
of an atom in the link. A temperature gradient accelerates the impurity in one
direction more than in the other, leading to an overall spin current similar to
the spin Seebeck effect.

text: Recently it was shown that anyons on the two-sphere naturally arise from a
system of molecular impurities exchanging angular momentum with a many-particle
bath (Phys. Rev. Lett. 126, 015301 (2021)). Here we further advance this approach
and rigorously demonstrate that in the experimentally realized regime the lowest
spectrum of two linear molecules immersed in superfluid helium corresponds to
the spectrum of two anyons on the sphere. We develop the formalism within the
framework of the recently experimentally observed angulon quasiparticle

text: The surface states of 3D topological insulators in general have negligible
quantum oscillations (QOs) when the chemical potential is tuned to the Dirac points.
In contrast, we find that topological Kondo insulators (TKIs) can support surface
states with an arbitrarily large Fermi surface (FS) when the chemical potential
is pinned to the Dirac point. We illustrate that these FSs give rise to finite-frequency
QOs, which can become comparable to the extremal area of the unhybridized bulk
bands. We show that this occurs when the crystal symmetry is lowered from cubic
to tetragonal in a minimal two-orbital model. We label such surface modes as 'shadow
surface states'. Moreover, we show that the sufficient next-nearest neighbor out-of-plane
hybridization leading to shadow surface states can be self-consistently stabilized
for tetragonal TKIs. Consequently, shadow surface states provide an important
example of high-frequency QOs beyond the context of cubic TKIs.

text: We combine experimental and theoretical approaches to explore excited rotational
states of molecules embedded in helium nanodroplets using CS2 and I2 as examples.
Laser-induced nonadiabatic molecular alignment is employed to measure spectral
lines for rotational states extending beyond those initially populated at the
0.37 K droplet temperature. We construct a simple quantum-mechanical model, based
on a linear rotor coupled to a single-mode bosonic bath, to determine the rotational
energy structure in its entirety. The calculated and measured spectral lines are
in good agreement. We show that the effect of the surrounding superfluid on molecular
rotation can be rationalized by a single quantity, the angular momentum, transferred
from the molecule to the droplet.

text: A few years ago, flow equations were introduced as a technique for calculating
the ground-state energies of cold Bose gases with and without impurities. In this
paper, we extend this approach to compute observables other than the energy. As
an example, we calculate the densities, and phase fluctuations of one-dimensional
Bose gases with one and two impurities. For a single mobile impurity, we use flow
equations to validate the mean-field results obtained upon the Lee-Low-Pines transformation.
We show that the mean-field approximation is accurate for all values of the boson-impurity
interaction strength as long as the phase coherence length is much larger than
the healing length of the condensate. For two static impurities, we calculate
impurity-impurity interactions induced by the Bose gas. We find that leading order
perturbation theory fails when boson-impurity interactions are stronger than boson-boson
interactions. The mean-field approximation reproduces the flow equation results
for all values of the boson-impurity interaction strength as long as boson-boson
interactions are weak.

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: Eigenstate thermalization in quantum many-body systems implies that eigenstates
at high energy are similar to random vectors. Identifying systems where at least
some eigenstates are nonthermal is an outstanding question. In this Letter we
show that interacting quantum models that have a nullspace—a degenerate subspace
of eigenstates at zero energy (zero modes), which corresponds to infinite temperature,
provide a route to nonthermal eigenstates. We analytically show the existence
of a zero mode which can be represented as a matrix product state for a certain
class of local Hamiltonians. In the more general case we use a subspace disentangling
algorithm to generate an orthogonal basis of zero modes characterized by increasing
entanglement entropy. We show evidence for an area-law entanglement scaling of
the least-entangled zero mode in the broad parameter regime, leading to a conjecture
that all local Hamiltonians with the nullspace feature zero modes with area-law
entanglement scaling and, as such, break the strong thermalization hypothesis.
Finally, we find zero modes in constrained models and propose a setup for observing
their experimental signatures.

text: A few-body cluster is a building block of a many-body system in a gas phase
provided the temperature at most is of the order of the binding energy of this
cluster. Here we illustrate this statement by considering a system of tubes filled
with dipolar distinguishable particles. We calculate the partition function, which
determines the probability to find a few-body cluster at a given temperature.
The input for our calculations—the energies of few-body clusters—is estimated
using the harmonic approximation. We first describe and demonstrate the validity
of our numerical procedure. Then we discuss the results featuring melting of the
zero-temperature many-body state into a gas of free particles and few-body clusters.
For temperature higher than its binding energy threshold, the dimers overwhelmingly
dominate the ensemble, where the remaining probability is in free particles. At
very high temperatures free (harmonic oscillator trap-bound) particle dominance
is eventually reached. This structure evolution appears both for one and two particles
in each layer providing crucial information about the behavior of ultracold dipolar
gases. The investigation addresses the transition region between few- and many-body
physics as a function of temperature using a system of ten dipoles in five tubes.

text: We explore the time evolution of two impurities in a trapped one-dimensional
Bose gas that follows a change of the boson-impurity interaction. We study the
induced impurity-impurity interactions and their effect on the quench dynamics.
In particular, we report on the size of the impurity cloud, the impurity-impurity
entanglement, and the impurity-impurity correlation function. The presented numerical
simulations are based upon the variational multilayer multiconfiguration time-dependent
Hartree method for bosons. To analyze and quantify induced impurity-impurity correlations,
we employ an effective two-body Hamiltonian with a contact interaction. We show
that the effective model consistent with the mean-field attraction of two heavy
impurities explains qualitatively our results for weak interactions. Our findings
suggest that the quench dynamics in cold-atom systems can be a tool for studying
impurity-impurity correlations.
