text: Determining the phase diagram of systems consisting of smaller subsystems
'connected' via a tunable coupling is a challenging task relevant for a variety
of physical settings. A general question is whether new phases, not present in
the uncoupled limit, may arise. We use machine learning and a suitable quasidistance
between different points of the phase diagram to study layered spin models, in
which the spin variables constituting each of the uncoupled systems (to which
we refer as layers) are coupled to each other via an interlayer coupling. In such
systems, in general, composite order parameters involving spins of different layers
may emerge as a consequence of the interlayer coupling. We focus on the layered
Ising and Ashkin–Teller models as a paradigmatic case study, determining their
phase diagram via the application of a machine learning algorithm to the Monte
Carlo data. Remarkably our technique is able to correctly characterize all the
system phases also in the case of hidden order parameters, i.e. order parameters
whose expression in terms of the microscopic configurations would require additional
preprocessing of the data fed to the algorithm. We correctly retrieve the three
known phases of the Ashkin–Teller model with ferromagnetic couplings, including
the phase described by a composite order parameter. For the bilayer and trilayer
Ising models the phases we find are only the ferromagnetic and the paramagnetic
ones. Within the approach we introduce, owing to the construction of convolutional
neural networks, naturally suitable for layered image-like data with arbitrary
number of layers, no preprocessing of the Monte Carlo data is needed, also with
regard to its spatial structure. The physical meaning of our results is discussed
and compared with analytical data, where available. Yet, the method can be used
without any a priori knowledge of the phases one seeks to find and can be applied
to other models and structures.

text: Nature creates electrons with two values of the spin projection quantum number.
In certain applications, it is important to filter electrons with one spin projection
from the rest. Such filtering is not trivial, since spin-dependent interactions
are often weak, and cannot lead to any substantial effect. Here we propose an
efficient spin filter based upon scattering from a two-dimensional crystal, which
is made of aligned point magnets. The polarization of the outgoing electron flux
is controlled by the crystal, and reaches maximum at specific values of the parameters.
In our scheme, polarization increase is accompanied by higher reflectivity of
the crystal. High transmission is feasible in scattering from a quantum cavity
made of two crystals. Our findings can be used for studies of low-energy spin-dependent
scattering from two-dimensional ordered structures made of magnetic atoms or aligned
chiral molecules.

text: In the high spin–orbit-coupled Sr2IrO4, the high sensitivity of the ground
state to the details of the local lattice structure shows a large potential for
the manipulation of the functional properties by inducing local lattice distortions.
We use epitaxial strain to modify the Ir–O bond geometry in Sr2IrO4 and perform
momentum-dependent resonant inelastic X-ray scattering (RIXS) at the metal and
at the ligand sites to unveil the response of the low-energy elementary excitations.
We observe that the pseudospin-wave dispersion for tensile-strained Sr2IrO4 films
displays large softening along the [h,0] direction, while along the [h,h] direction
it shows hardening. This evolution reveals a renormalization of the magnetic interactions
caused by a strain-driven cross-over from anisotropic to isotropic interactions
between the magnetic moments. Moreover, we detect dispersive electron–hole pair
excitations which shift to lower (higher) energies upon compressive (tensile)
strain, manifesting a reduction (increase) in the size of the charge gap. This
behavior shows an intimate coupling between charge excitations and lattice distortions
in Sr2IrO4, originating from the modified hopping elements between the t2g orbitals.
Our work highlights the central role played by the lattice degrees of freedom
in determining both the pseudospin and charge excitations of Sr2IrO4 and provides
valuable information toward the control of the ground state of complex oxides
in the presence of high spin–orbit coupling.

text: Several realistic spin-orbital models for transition metal oxides go beyond
the classical expectations and could be understood only by employing the quantum
entanglement. Experiments on these materials confirm that spin-orbital entanglement
has measurable consequences. Here, we capture the essential features of spin-orbital
entanglement in complex quantum matter utilizing 1D spin-orbital model which accommodates
SU(2)⊗SU(2) symmetric Kugel-Khomskii superexchange as well as the Ising on-site
spin-orbit coupling. Building on the results obtained for full and effective models
in the regime of strong spin-orbit coupling, we address the question whether the
entanglement found on superexchange bonds always increases when the Ising spin-orbit
coupling is added. We show that (i) quantum entanglement is amplified by strong
spin-orbit coupling and, surprisingly, (ii) almost classical disentangled states
are possible. We complete the latter case by analyzing how the entanglement existing
for intermediate values of spin-orbit coupling can disappear for higher values
of this coupling.

text: "In ecology, climate and other fields, (sub)systems have been identified that
can transition into a qualitatively different state when a critical threshold
or tipping point in a driving process is crossed. An understanding of those tipping
elements is of great interest given the increasing influence of humans on the
biophysical Earth system. Complex interactions exist between tipping elements,
e.g. physical mechanisms connect subsystems of the climate system. Based on earlier
work on such coupled nonlinear systems, we systematically assessed the qualitative
long-term behaviour of interacting tipping elements. We developed an understanding
of the consequences of interactions\r\non the tipping behaviour allowing for tipping
cascades to emerge under certain conditions. The (narrative) application of\r\nthese
qualitative results to real-world examples of interacting tipping elements indicates
that tipping cascades with profound consequences may occur: the interacting Greenland
ice sheet and thermohaline ocean circulation might tip before the tipping points
of the isolated subsystems are crossed. The eutrophication of the first lake in
a lake chain might propagate through the following lakes without a crossing of
their individual critical nutrient input levels. The possibility of emerging cascading
tipping dynamics calls for the development of a unified theory of interacting
tipping elements and the quantitative analysis of interacting real-world tipping
elements."

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: "The oft-quoted dictum by Arthur Schawlow: ``A diatomic molecule has one atom
too many'' has been disavowed. Inspired by the possibility to experimentally manipulate
and enhance chemical reactivity in helium nanodroplets, we investigate the rotation
of coupled cold molecules in the presence of a many-body environment.\r\nIn this
thesis, we introduce new variational approaches to quantum impurities and apply
them to the Fröhlich polaron - a quasiparticle formed out of an electron (or other
point-like impurity) in a polar medium, and to the angulon - a quasiparticle formed
out of a rotating molecule in a bosonic bath.\r\nWith this theoretical toolbox,
we reveal the self-localization transition for the angulon quasiparticle. We show
that, unlike for polarons, self-localization of angulons occurs at finite impurity-bath
coupling already at the mean-field level. The transition is accompanied by the
spherical-symmetry breaking of the angulon ground state and a discontinuity in
the first derivative of the ground-state energy. Moreover, the type of symmetry
breaking is dictated by the symmetry of the microscopic impurity-bath interaction,
which leads to a number of distinct self-localized states. \r\nFor the system
containing multiple impurities, by analogy with the bipolaron, we introduce the
biangulon quasiparticle describing two rotating molecules that align with respect
to each other due to the effective attractive interaction mediated by the excitations
of the bath. We study this system from the strong-coupling regime to the weak
molecule-bath interaction regime. We show that the molecules tend to have a strong
alignment in the ground state, the biangulon shows shifted angulon instabilities
and an additional spectral instability, where resonant angular momentum transfer
between the molecules and the bath takes place. Finally, we introduce a diagonalization
scheme that allows us to describe the transition from two separated angulons to
a biangulon as a function of the distance between the two molecules."

text: In the superconducting regime of FeTe(1−x)Sex, there exist two types of vortices
which are distinguished by the presence or absence of zero-energy states in their
core. To understand their origin, we examine the interplay of Zeeman coupling
and superconducting pairings in three-dimensional metals with band inversion.
Weak Zeeman fields are found to suppress intraorbital spin-singlet pairing, known
to localize the states at the ends of the vortices on the surface. On the other
hand, an orbital-triplet pairing is shown to be stable against Zeeman interactions,
but leads to delocalized zero-energy Majorana modes which extend through the vortex.
In contrast, the finite-energy vortex modes remain localized at the vortex ends
even when the pairing is of orbital-triplet form. Phenomenologically, this manifests
as an observed disappearance of zero-bias peaks within the cores of topological
vortices upon an increase of the applied magnetic field. The presence of magnetic
impurities in FeTe(1−x)Sex, which are attracted to the vortices, would lead to
such Zeeman-induced delocalization of Majorana modes in a fraction of vortices
that capture a large enough number of magnetic impurities. Our results provide
an explanation for the dichotomy between topological and nontopological vortices
recently observed in FeTe(1−x)Sex.

text: The concept of the entanglement between spin and orbital degrees of freedom
plays a crucial role in our understanding of various phases and exotic ground
states in a broad class of materials, including orbitally ordered materials and
spin liquids. We investigate how the spin-orbital entanglement in a Mott insulator
depends on the value of the spin-orbit coupling of the relativistic origin. To
this end, we numerically diagonalize a one-dimensional spin-orbital model with
Kugel-Khomskii exchange interactions between spins and orbitals on different sites
supplemented by the on-site spin-orbit coupling. In the regime of small spin-orbit
coupling with regard to the spin-orbital exchange, the ground state to a large
extent resembles the one obtained in the limit of vanishing spin-orbit coupling.
On the other hand, for large spin-orbit coupling the ground state can, depending
on the model parameters, either still show negligible spin-orbital entanglement
or evolve to a highly spin-orbitally-entangled phase with completely distinct
properties that are described by an effective XXZ model. The presented results
suggest that (i) the spin-orbital entanglement may be induced by large on-site
spin-orbit coupling, as found in the 5d transition metal oxides, such as the iridates;
(ii) for Mott insulators with weak spin-orbit coupling of Ising type, such as,
e.g., the alkali hyperoxides, the effects of the spin-orbit coupling on the ground
state can, in the first order of perturbation theory, be neglected.

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.

text: We study a mobile quantum impurity, possessing internal rotational degrees
of freedom, confined to a ring in the presence of a many-particle bosonic bath.
By considering the recently introduced rotating polaron problem, we define the
Hamiltonian and examine the energy spectrum. The weak-coupling regime is studied
by means of a variational ansatz in the truncated Fock space. The corresponding
spectrum indicates that there emerges a coupling between the internal and orbital
angular momenta of the impurity as a consequence of the phonon exchange. We interpret
the coupling as a phonon-mediated spin-orbit coupling and quantify it by using
a correlation function between the internal and the orbital angular momentum operators.
The strong-coupling regime is investigated within the Pekar approach, and it is
shown that the correlation function of the ground state shows a kink at a critical
coupling, that is explained by a sharp transition from the noninteracting state
to the states that exhibit strong interaction with the surroundings. The results
might find applications in such fields as spintronics or topological insulators
where spin-orbit coupling is of crucial importance.

text: When short-range attractions are combined with long-range repulsions in colloidal
particle systems, complex microphases can emerge. Here, we study a system of isotropic
particles, which can form lamellar structures or a disordered fluid phase when
temperature is varied. We show that, at equilibrium, the lamellar structure crystallizes,
while out of equilibrium, the system forms a variety of structures at different
shear rates and temperatures above melting. The shear-induced ordering is analyzed
by means of principal component analysis and artificial neural networks, which
are applied to data of reduced dimensionality. Our results reveal the possibility
of inducing ordering by shear, potentially providing a feasible route to the fabrication
of ordered lamellar structures from isotropic particles.

text: Organic materials are known to feature long spin-diffusion times, originating
in a generally small spin–orbit coupling observed in these systems. From that
perspective, chiral molecules acting as efficient spin selectors pose a puzzle
that attracted a lot of attention in recent years. Here, we revisit the physical
origins of chiral-induced spin selectivity (CISS) and propose a simple analytic
minimal model to describe it. The model treats a chiral molecule as an anisotropic
wire with molecular dipole moments aligned arbitrarily with respect to the wire’s
axes and is therefore quite general. Importantly, it shows that the helical structure
of the molecule is not necessary to observe CISS and other chiral nonhelical molecules
can also be considered as potential candidates for the CISS effect. We also show
that the suggested simple model captures the main characteristics of CISS observed
in the experiment, without the need for additional constraints employed in the
previous studies. The results pave the way for understanding other related physical
phenomena where the CISS effect plays an essential role.

text: "Alignment of OCS, CS2, and I2 molecules embedded in helium nanodroplets is
measured as a function\r\nof time following rotational excitation by a nonresonant,
comparatively weak ps laser pulse. The distinct\r\npeaks in the power spectra,
obtained by Fourier analysis, are used to determine the rotational, B, and\r\ncentrifugal
distortion, D, constants. For OCS, B and D match the values known from IR spectroscopy.
For\r\nCS2 and I2, they are the first experimental results reported. The alignment
dynamics calculated from the\r\ngas-phase rotational Schrödinger equation, using
the experimental in-droplet B and D values, agree in\r\ndetail with the measurement
for all three molecules. The rotational spectroscopy technique for molecules in\r\nhelium
droplets introduced here should apply to a range of molecules and complexes."

text: "We study the effect of a linear tunneling coupling between two-dimensional
systems, each separately\r\nexhibiting the topological Berezinskii-Kosterlitz-Thouless
(BKT) transition. In the uncoupled limit, there\r\nare two phases: one where the
one-body correlation functions are algebraically decaying and the other with\r\nexponential
decay. When the linear coupling is turned on, a third BKT-paired phase emerges,
in which one-body correlations are exponentially decaying, while two-body correlation
functions exhibit power-law\r\ndecay. We perform numerical simulations in the
paradigmatic case of two coupled XY models at finite\r\ntemperature, finding evidences
that for any finite value of the interlayer coupling, the BKT-paired phase is\r\npresent.
We provide a picture of the phase diagram using a renormalization group approach."

text: We study few-body bound states of charged particles subject to attractive
zero-range/short-range plus repulsive Coulomb interparticle forces. The characteristic
length scales of the system at zero energy are set by the Coulomb length scale
D and the Coulomb-modified effective range r eff. We study shallow bound states
of charged particles with D >> r eff and show that these systems obey universal
scaling laws different from neutral particles. An accurate description of these
states requires both the Coulomb-modified scattering length and the effective
range unless the Coulomb interaction is very weak (D -> ). Our findings are relevant
for bound states whose spatial extent is significantly larger than the range of
the attractive potential. These states enjoy universality – their character is
independent of the shape of the short-range potential.

text: We investigate the ground-state energy of a one-dimensional Fermi gas with
two bosonic impurities. We consider spinless fermions with no fermion-fermion
interactions. The fermion-impurity and impurity-impurity interactions are modeled
with Dirac delta functions. First, we study the case where impurity and fermion
have equal masses, and the impurity-impurity two-body interaction is identical
to the fermion-impurity interaction, such that the system is solvable with the
Bethe ansatz. For attractive interactions, we find that the energy of the impurity-impurity
subsystem is below the energy of the bound state that exists without the Fermi
gas. We interpret this as a manifestation of attractive boson-boson interactions
induced by the fermionic medium, and refer to the impurity-impurity subsystem
as an in-medium bound state. For repulsive interactions, we find no in-medium
bound states. Second, we construct an effective model to describe these interactions,
and compare its predictions to the exact solution. We use this effective model
to study nonintegrable systems with unequal masses and/or potentials. We discuss
parameter regimes for which impurity-impurity attraction induced by the Fermi
gas can lead to the formation of in-medium bound states made of bosons that repel
each other in the absence of the Fermi gas.

text: The angular momentum of molecules, or, equivalently, their rotation in three-dimensional
space, is ideally suited for quantum control. Molecular angular momentum is naturally
quantized, time evolution is governed by a well-known Hamiltonian with only a
few accurately known parameters, and transitions between rotational levels can
be driven by external fields from various parts of the electromagnetic spectrum.
Control over the rotational motion can be exerted in one-, two-, and many-body
scenarios, thereby allowing one to probe Anderson localization, target stereoselectivity
of bimolecular reactions, or encode quantum information to name just a few examples.
The corresponding approaches to quantum control are pursued within separate, and
typically disjoint, subfields of physics, including ultrafast science, cold collisions,
ultracold gases, quantum information science, and condensed-matter physics. It
is the purpose of this review to present the various control phenomena, which
all rely on the same underlying physics, within a unified framework. To this end,
recall the Hamiltonian for free rotations, assuming the rigid rotor approximation
to be valid, and summarize the different ways for a rotor to interact with external
electromagnetic fields. These interactions can be exploited for control—from achieving
alignment, orientation, or laser cooling in a one-body framework, steering bimolecular
collisions, or realizing a quantum computer or quantum simulator in the many-body
setting.

text: Problems involving quantum impurities, in which one or a few particles are
interacting with a macroscopic environment, represent a pervasive paradigm, spanning
across atomic, molecular, and condensed-matter physics. In this paper we introduce
new variational approaches to quantum impurities and apply them to the Fröhlich
polaron–a quasiparticle formed out of an electron (or other point-like impurity)
in a polar medium, and to the angulon–a quasiparticle formed out of a rotating
molecule in a bosonic bath. We benchmark these approaches against established
theories, evaluating their accuracy as a function of the impurity-bath coupling.
