text: We show that the simplest of existing molecules—closed-shell diatomics not
interacting with one another—host topological charges when driven by periodic
far-off-resonant laser pulses. A periodically kicked molecular rotor can be mapped
onto a “crystalline” lattice in angular momentum space. This allows us to define
quasimomenta and the band structure in the Floquet representation, by analogy
with the Bloch waves of solid-state physics. Applying laser pulses spaced by 1/3
of the molecular rotational period creates a lattice with three atoms per unit
cell with staggered hopping. Within the synthetic dimension of the laser strength,
we discover Dirac cones with topological charges. These Dirac cones, topologically
protected by reflection and time-reversal symmetry, are reminiscent of (although
not equivalent to) that seen in graphene. They—and the corresponding edge states—are
broadly tunable by adjusting the laser strength and can be observed in present-day
experiments by measuring molecular alignment and populations of rotational levels.
This paves the way to study controllable topological physics in gas-phase experiments
with small molecules as well as to classify dynamical molecular states by their
topological invariants.

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.'

focusing on the experimentally relevant case of a ⁴¹K - ⁸⁷Rb mixture, with the

We present results for the miscible and immiscible regimes, as well as for the

exotic states where the impurity localizes either at the center or\r\nat the surface

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.

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: 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: We investigate the formation of magnetic Bose polaron, an impurity atom dressed
by spin-wave excitations, in a one-dimensional spinor Bose gas. Within an effective
potential model, the impurity is strongly confined by the host excitations which
can even overcome the impurity-medium repulsion leading to a self-localized quasi-particle
state. The phase diagram of the attractive and self-bound repulsive magnetic polaron,
repulsive non-magnetic (Fröhlich-type) polaron and impurity-medium phase-separation
regimes is explored with respect to the Rabi-coupling between the spin components,
spin–spin interactions and impurity-medium coupling. The residue of such magnetic
polarons decreases substantially in both strong attractive and repulsive branches
with strong impurity-spin interactions, illustrating significant dressing of the
impurity. The impurity can be used to probe and maneuver the spin polarization
of the magnetic medium while suppressing ferromagnetic spin–spin correlations.
It is shown that mean-field theory fails as the spinor gas approaches immiscibility
since the generated spin-wave excitations are prominent. Our findings illustrate
that impurities can be utilized to generate controllable spin–spin correlations
and magnetic polaron states which can be realized with current cold atom setups.

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: 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: 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: 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.

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.
