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: Inspired by the possibility to experimentally manipulate and enhance chemical
reactivity in helium nanodroplets, we investigate the effective interaction and
the resulting correlations between two diatomic molecules immersed in a bath of
bosons. 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 in different parameter regimes and apply several theoretical
approaches to describe its properties. Using a Born–Oppenheimer approximation,
we investigate the dependence of the effective intermolecular interaction on the
rotational state of the two molecules. In the strong-coupling regime, a product-state
ansatz shows that the molecules tend to have a strong alignment in the ground
state. To investigate the system in the weak-coupling regime, we apply a one-phonon
excitation variational ansatz, which allows us to access the energy spectrum.
In comparison to the angulon quasiparticle, the biangulon shows shifted angulon
instabilities and an additional spectral instability, where resonant angular momentum
transfer between the molecules and the bath takes place. These features are proposed
as an experimentally observable signature for the formation of the biangulon quasiparticle.
Finally, by using products of single angulon and bare impurity wave functions
as basis states, 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: 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: "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: 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: 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: "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: "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: 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.
