  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: 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: 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: 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
    can be used for the minimization of damage during imaging in HIM or optimization
    of the patterning process.
