text: We demonstrate that a sodium dimer, Na2(13Σ+u), residing on the surface of
a helium nanodroplet, can be set into rotation by a nonresonant 1.0 ps infrared
laser pulse. The time-dependent degree of alignment measured, exhibits a periodic,
gradually decreasing structure that deviates qualitatively from that expected
for gas-phase dimers. Comparison to alignment dynamics calculated from the time-dependent
rotational Schrödinger equation shows that the deviation is due to the alignment
dependent interaction between the dimer and the droplet surface. This interaction
confines the dimer to the tangential plane of the droplet surface at the point
where it resides and is the reason that the observed alignment dynamics is also
well described by a 2D quantum rotor model.

text: The model of a ring threaded by the Aharonov-Bohm flux underlies our understanding
of a coupling between gauge potentials and matter. The typical formulation of
the model is based upon a single particle picture, and should be extended when
interactions with other particles become relevant. Here, we illustrate such an
extension for a particle in an Aharonov-Bohm ring subject to interactions with
a weakly interacting Bose gas. We show that the ground state of the system can
be described using the Bose-polaron concept—a particle dressed by interactions
with a bosonic environment. We connect the energy spectrum to the effective mass
of the polaron, and demonstrate how to change currents in the system by tuning
boson-particle interactions. Our results suggest the Aharonov-Bohm ring as a platform
for studying coherence and few- to many-body crossover of quasi-particles that
arise from an impurity immersed in a medium.

text: The development of two-dimensional materials has resulted in a diverse range
of novel, high-quality compounds with increasing complexity. A key requirement
for a comprehensive quantitative theory is the accurate determination of these
materials' band structure parameters. However, this task is challenging due to
the intricate band structures and the indirect nature of experimental probes.
In this work, we introduce a general framework to derive band structure parameters
from experimental data using deep neural networks. We applied our method to the
penetration field capacitance measurement of trilayer graphene, an effective probe
of its density of states. First, we demonstrate that a trained deep network gives
accurate predictions for the penetration field capacitance as a function of tight-binding
parameters. Next, we use the fast and accurate predictions from the trained network
to automatically determine tight-binding parameters directly from experimental
data, with extracted parameters being in a good agreement with values in the literature.
We conclude by discussing potential applications of our method to other materials
and experimental techniques beyond penetration field capacitance.

text: We demonstrate the possibility of a coupling between the magnetization direction
of a ferromagnet and the tilting angle of adsorbed achiral molecules. To illustrate
the mechanism of the coupling, we analyze a minimal Stoner model that includes
Rashba spin–orbit coupling due to the electric field on the surface of the ferromagnet.
The proposed mechanism allows us to study magnetic anisotropy of the system with
an extended Stoner–Wohlfarth model and argue that adsorbed achiral molecules can
change magnetocrystalline anisotropy of the substrate. Our research aims to motivate
further experimental studies of the current-free chirality induced spin selectivity
effect involving both enantiomers.

text: We present a minimal model of ferroelectric large polarons, which are suggested
as one of the mechanisms responsible for the unique charge transport properties
of hybrid perovskites. We demonstrate that short-ranged charge–rotor interactions
lead to long-range ferroelectric ordering of rotors, which strongly affects the
carrier mobility. In the nonperturbative regime, where our theory cannot be reduced
to any of the earlier models, we reveal that the polaron is characterized by large
coherence length and a roughly tenfold increase of the effective mass as compared
to the bare mass. These results are in good agreement with other theoretical predictions
for ferroelectric polarons. Our model establishes a general phenomenological framework
for ferroelectric polarons providing the starting point for future studies of
their role in the transport properties of hybrid organic-inorganic perovskites.

text: Cold atomic gases have become a paradigmatic system for exploring fundamental
physics, which at the same time allows for applications in quantum technologies.
The accelerating developments in the field have led to a highly advanced set of
engineering techniques that, for example, can tune interactions, shape the external
geometry, select among a large set of atomic species with different properties,
or control the number of atoms. In particular, it is possible to operate in lower
dimensions and drive atomic systems into the strongly correlated regime. In this
review, we discuss recent advances in few-body cold atom systems confined in low
dimensions from a theoretical viewpoint. We mainly focus on bosonic systems in
one dimension and provide an introduction to the static properties before we review
the state-of-the-art research into quantum dynamical processes stimulated by the
presence of correlations. Besides discussing the fundamental physical phenomena
arising in these systems, we also provide an overview of the calculational and
numerical tools and methods that are commonly used, thus delivering a balanced
and comprehensive overview of the field. We conclude by giving an outlook on possible
future directions that are interesting to explore in these correlated systems.

text: We study the out-of-equilibrium quantum dynamics of dipolar polarons, i.e.,
impurities immersed in a dipolar Bose-Einstein condensate, after a quench of the
impurity-boson interaction. We show that the dipolar nature of the condensate
and of the impurity results in anisotropic relaxation dynamics, in particular,
anisotropic dressing of the polaron. More relevantly for cold-atom setups, quench
dynamics is strongly affected by the interplay between dipolar anisotropy and
trap geometry. Our findings pave the way for simulating impurities in anisotropic
media utilizing experiments with dipolar mixtures.

text: "We investigate spin-charge separation of a spin-\r\n1\r\n2\r\n Fermi system
confined in a triple well where multiple bands are occupied. We assume that our
finite fermionic system is close to fully spin polarized while being doped by
a hole and an impurity fermion with opposite spin. Our setup involves ferromagnetic
couplings among the particles in different bands, leading to the development of
strong spin-transport correlations in an intermediate interaction regime. Interactions
are then strong enough to lift the degeneracy among singlet and triplet spin configurations
in the well of the spin impurity but not strong enough to prohibit hole-induced
magnetic excitations to the singlet state. Despite the strong spin-hole correlations,
the system exhibits spin-charge deconfinement allowing for long-range entanglement
of the spatial and spin degrees of freedom."

text: "We prove the r-spin cobordism hypothesis in the setting of (weak) 2-categories
for every positive integer r: the 2-groupoid of 2-dimensional fully extended r-spin
TQFTs with given target is equivalent to the homotopy fixed points of an induced
Spin 2r -action. In particular, such TQFTs are classified by fully dualisable
objects together with a trivialisation of the rth power of their Serre automorphisms.
For r=1, we recover the oriented case (on which our proof builds), while ordinary
spin structures correspond to r=2.\r\nTo construct examples, we explicitly describe
Spin 2r-homotopy fixed points in the equivariant completion of any symmetric
monoidal 2-category. We also show that every object in a 2-category of Landau–Ginzburg
models gives rise to fully extended spin TQFTs and that half of these do not factor
through the oriented bordism 2-category."

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 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 nonadditive systems very well. In particular, we recover exact
diagonalization in all regimes tested and 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: We review our theoretical results of the sound propagation in two-dimensional
(2D) systems of ultracold fermionic and bosonic atoms. In the superfluid phase,
characterized by the spontaneous symmetry breaking of the U(1) symmetry, there
is the coexistence of first and second sound. In the case of weakly-interacting
repulsive bosons, we model the recent measurements of the sound velocities of
39K atoms in 2D obtained in the weakly-interacting regime and around the Berezinskii–Kosterlitz–Thouless
(BKT) superfluid-to-normal transition temperature. In particular, we perform a
quite accurate computation of the superfluid density and show that it is reasonably
consistent with the experimental results. For superfluid attractive fermions,
we calculate the first and second sound velocities across the whole BCS-BEC crossover.
In the low-temperature regime, we reproduce the recent measurements of first-sound
speed with 6Li atoms. We also predict that there is mixing between sound modes
only in the finite-temperature BEC regime.

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: In this Thesis, I study composite quantum impurities with variational techniques,
both inspired by machine learning as well as fully analytic. I supplement this
with exploration of other applications of machine learning, in particular artificial
neural networks, in many-body physics. In Chapters 3 and 4, I study quasiparticle
systems with variational approach. I derive a Hamiltonian describing the angulon
quasiparticle in the presence of a magnetic field. I apply analytic variational
treatment to this Hamiltonian. Then, I introduce a variational approach for non-additive
systems, based on artificial neural networks. I exemplify this approach on the
example of the polaron quasiparticle (Fröhlich Hamiltonian). In Chapter 5, I continue
using artificial neural networks, albeit in a different setting. I apply artificial
neural networks to detect phases from snapshots of two types physical systems.
Namely, I study Monte Carlo snapshots of multilayer classical spin models as well
as molecular dynamics maps of colloidal systems. The main type of networks that
I use here are convolutional neural networks, known for their applicability to
image data.

text: A critical overview of the theory of the chirality-induced spin selectivity
(CISS) effect, that is, phenomena in which the chirality of molecular species
imparts significant spin selectivity to various electron processes, is provided.
Based on discussions in a recently held workshop, and further work published since,
the status of CISS effects—in electron transmission, electron transport, and chemical
reactions—is reviewed. For each, a detailed discussion of the state-of-the-art
in theoretical understanding is provided and remaining challenges and research
opportunities are identified.

text: We study an impurity with a resonance level whose position coincides with
the Fermi energy of the surrounding Fermi gas. An impurity causes a rapid variation
of the scattering phase shift for fermions at the Fermi surface, introducing a
new characteristic length scale into the problem. We investigate manifestations
of this length scale in the self-energy of the impurity and in the density of
the bath. Our calculations reveal a model-independent deformation of the density
of the Fermi gas, which is determined by the width of the resonance. To provide
a broader picture, we investigate time evolution of the density in quench dynamics,
and study the behavior of the system at finite temperatures. Finally, we briefly
discuss implications of our findings for the Fermi-polaron problem.

text: Rotational dynamics of D2 molecules inside helium nanodroplets is induced
by a moderately intense femtosecond pump pulse and measured as a function of time
by recording the yield of HeD+ ions, created through strong-field dissociative
ionization with a delayed femtosecond probe pulse. The yield oscillates with a
period of 185 fs, reflecting field-free rotational wave packet dynamics, and the
oscillation persists for more than 500 periods. Within the experimental uncertainty,
the rotational constant BHe of the in-droplet D2 molecule, determined by Fourier
analysis, is the same as Bgas for an isolated D2 molecule. Our observations show
that the D2 molecules inside helium nanodroplets essentially rotate as free D2
molecules.

text: 'We investigate the ground-state properties of weakly repulsive one-dimensional
bosons in the presence of an attractive zero-range impurity potential. First,
we derive mean-field solutions to the problem on a finite ring for the two asymptotic
cases: (i) all bosons are bound to the impurity and (ii) all bosons are in a scattering
state. Moreover, we derive the critical line that separates these regimes in the
parameter space. In the thermodynamic limit, this critical line determines the
maximum number of bosons that can be bound by the impurity potential, forming
an artificial atom. Second, we validate the mean-field results using the flow
equation approach and the multi-layer multi-configuration time-dependent Hartree
method for atomic mixtures. While beyond-mean-field effects destroy long-range
order in the Bose gas, the critical boson number is unaffected. Our findings are
important for understanding such artificial atoms in low-density Bose gases with
static and mobile impurities.'

text: 'We compare recent experimental results [Science 375, 528 (2022)] of the superfluid
unitary Fermi gas near the critical temperature with a thermodynamic model based
on the elementary excitations of the system. We find good agreement between experimental
data and our theory for several quantities such as first sound, second sound,
and superfluid fraction. We also show that mode mixing between first and second
sound occurs. Finally, we characterize the response amplitude to a density perturbation:
Close to the critical temperature both first and second sound can be excited through
a density perturbation, whereas at lower temperatures only the first sound mode
exhibits a significant response.'

text: "We study the fate of an impurity in an ultracold heteronuclear Bose mixture,
focusing on the experimentally relevant case of a ⁴¹K - ⁸⁷Rb mixture, with the
impurity in a ⁴¹K hyperfine state. Our paper provides a comprehensive description
of an impurity in a BEC mixture with contact interactions across its phase diagram.
We present results for the miscible and immiscible regimes, as well as for the
impurity in a self-bound quantum droplet. Here, varying the interactions, we find
exotic states where the impurity localizes either at the center or\r\nat the surface
of the droplet. "

text: Recently it became possible to study highly excited rotational states of molecules
in superfluid helium through nonadiabatic alignment experiments (Cherepanov et
al 2021 Phys. Rev. A 104 L061303). This calls for theoretical approaches that
go beyond explaining renormalized values of molecular spectroscopic constants,
which suffices when only the lowest few rotational states are involved. As the
first step in this direction, here we present a basic quantum mechanical model
describing highly excited rotational states of molecules in superfluid helium
nanodroplets. We show that a linear molecule immersed in a superfluid can be seen
as an effective symmetric top, similar to the rotational structure of radicals,
such as OH or NO, but with the angular momentum of the superfluid playing the
role of the electronic angular momentum in free molecules. The simple theory sheds
light onto what happens when the rotational angular momentum of the molecule increases
beyond the lowest excited states accessible by infrared spectroscopy. In addition,
the model allows to estimate the effective rotational and centrifugal distortion
constants for a broad range of species and to explain the crossover between light
and heavy molecules in superfluid 4He in terms of the many-body wavefunction structure.
Some of the above mentioned insights can be acquired by analyzing a simple 2 ×
2 matrix.
