text: We present a general theoretical framework for helical dichroism (HD), establishing
an explicit link between chiral resolution and orbital angular momentum (OAM)
exchange in light–matter interaction. Tracing microscopic mechanisms of the OAM
transfer, we derive rotational selection rules, which establish that HD emerges
only from the spin–orbit coupling of light, even for beams without the far-field
OAM. Our findings refine the conditions for observing HD, provide a tool to re-examine
the outcome of prior experiments, and guide future designs for chiral sensing
with structured light.

text: Despite its pivotal role in optical manipulation, high capacity communications,
and quantum information, a general measure of orbital angular momentum (OAM) in
structured light remains elusive. In optical fields, where multiple vortices coexist,
the local nature of vortex OAM and the absence of a common rotation axis make
the total OAM of the field difficult to quantify. Here, we introduce the R index—a
metric that captures the intrinsic OAM content of any structured optical field,
from pure Laguerre–Gaussian modes to arbitrary multi vortex superpositions. Not
only does this metric quantify the total OAM, it also assesses field purity, providing
insight into the fidelity and robustness of the OAM generation. By unifying OAM
characterization into a single figure of merit, the R index enables direct comparison
across diverse beam profiles and facilitates the identification of optimal configurations
for both foundational studies and applied technologies.

text: 'Rotations are found in physics problems at all scales: from spatial motion
of celestial bodies, to transitions between quantum states of atoms and molecules.
Mathematically, they represent a fundamental class of transformations and symmetries.
Unlike spatial displacements, rotational transformations in three-dimensional
space are non-commutative: the result of applying a sequence of rotations depends
on the order of these operations. This feature makes the emergent physics that
involves rotations rather intricate, but instrumental for studies of highly-interconnected
many-body systems. In the presence of an environment, rotational properties of
an object change, due to the interaction with particles of the environment. Owing
to the complexity of this interaction, it can be engineered to exhibit certain
properties of interest. In this Thesis, we examine several scenarios of how the
rotational behavior of an impurity can be modified by interactions with its environment.'

text: In standard quantum electrodynamics (QED), the so-called non-minimal (Pauli)
coupling is suppressed for elementary particles and has no physical implications.
Here, we show that the Pauli term naturally appears in a known family of Dirac
materials—the lead-halide perovskites, suggesting a novel playground for the study
of analog QED effects. We outline measurable manifestations of the Pauli term
in the phenomena pertaining to (i) relativistic corrections to bound states (ii)
the Klein paradox, and (iii) spin effects in scattering. In particular, we demonstrate
that (a) the binding energy of an electron in the vicinity of a positively charged
defect is noticeably decreased due to the polarizability of lead ions and the
appearance of a Darwin-like term, (b) strong spin-orbit coupling due to the Pauli
term affects the exciton states, and (c) scattering of an electron off an energy
barrier with broken mirror symmetry produces spin polarization in the outgoing
current. Our study adds to the understanding of quantum phenomena in lead-halide
perovskites and paves the way for tabletop simulations of analog Dirac-Pauli equations.

text: We present a theory describing the interaction of structured light, such as
light carrying orbital angular momentum, with molecules. The light-matter interaction
Hamiltonian we derive is expressed through couplings between spherical gradients
of the electric field and the (transition) electric multipole moments of a particle
of any nontrivial rotation point group. Our model can therefore accommodate an
arbitrary complexity of the molecular and electric field structure, and it can
be straightforwardly extended to atoms or nanostructures. Applying this framework
to rovibrational spectroscopy of molecules, we uncover the general mechanism of
angular momentum exchange between the spin and orbital angular momenta of light,
molecular rotation, and its center-of-mass motion. We show that the nonzero vorticity
of Laguerre-Gaussian beams can strongly enhance certain rovibrational transitions
that are considered forbidden in the case of nonhelical light. We discuss the
experimental requirements for the observation of these forbidden transitions in
state-of-the-art spatially resolved spectroscopy measurements.

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: The main idea behind the Core Project is to teach first year students at IST
scientific communication skills and let them practice by presenting their research
within an interdisciplinary environment. Over the course of the first semester,
students participated in seminars, where they shared their results with the colleagues
from other fields and took part in discussions on relevant subjects. The main
focus during this sessions was on delivering the information in a simplified and
comprehensible way, going into the very basics of a subject if necessary. At the
end, the students were asked to present their research in the written form to
exercise their writing skills. The reports were gathered in this document. All
of them were reviewed by the teaching assistants and write-ups illustrating unique
stylistic features and, in general, an outstanding level of writing skills, were
honorably mentioned in the section "Selected Reports".

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: Focused ion beams perfectly suit for patterning two-dimensional (2D) materials,
but the optimization of irradiation parameters requires full microscopic understanding
of defect production mechanisms. In contrast to freestanding 2D systems, the details
of damage creation in supported 2D materials are not fully understood, whereas
the majority of experiments have been carried out for 2D targets deposited on
substrates. Here, we suggest a universal and computationally efficient scheme
to model the irradiation of supported 2D materials, which combines analytical
potential molecular dynamics with Monte Carlo simulations and makes it possible
to independently assess the contributions to the damage from backscattered ions
and atoms sputtered from the substrate. Using the scheme, we study the defect
production in graphene and MoS2 sheets, which are the two most important and wide-spread
2D materials, deposited on a SiO2 substrate. For helium and neon ions with a wide
range of initial ion energies including those used in a commercial helium ion
microscope (HIM), we demonstrate that depending on the ion energy and mass, the
defect production in 2D systems can be dominated by backscattered ions and sputtered
substrate atoms rather than by the direct ion impacts and that the amount of damage
in 2D materials heavily depends on whether a substrate is present or not. We also
study the factors which limit the spatial resolution of the patterning process.
Our results, which agree well with the available experimental data, provide not
only insights into defect production but also quantitative information, which
