Opis zadań:

The successful PhD candidates will be part of the group created by dr Jacek Herbrych (https://herbrychjacek.bitbucket.io/) within project NCN SONATA BIS 13 2023/50/E/ST3/00033 entitled “Properties of low-dimensional quantum systems with charge, spin, and orbital degrees of freedom.” The project's scientific goal is to investigate the novel phenomena of multi-orbital systems, i.e., in systems with many local degrees of freedom (orbital, spin, and charge). A prominent example of the phenomena unique to the multi-orbital system is the so-called orbital-selective Mott phase (OSMP). Competing interactions can lead to the selective localization of electrons on some orbitals. Such insulating bands coexist with the metallic band (or bands) with itinerant electrons. The dispersion relation (the momentum dependence) of the latter is routinely measured using spectroscopic tools (e.g., single-particle spectral function measured by the angle-resolved photoemission spectroscopy, dynamical spin structure factor measured by inelastic neutron scattering, or other tools like resonant inelastic X-ray scattering spectroscopy, Raman spectroscopy, or reflection/transmission measurements). However, due to the enormous Hilbert space of multi-orbital systems, the theoretical analysis of the dynamical properties of such systems is mostly missing (especially the momentum-resolved quantities). The main scientific aim of this proposal is to investigate properties (and discover novel exotic phases) of the models with many competing energy scales originating from spin, charge, and orbital degrees of freedom, i.e., to investigate multi-orbital Hubbard model, generalized Kondo-Heisenberg model, spin-orbital model, and effective models which describe the physics mentioned above (i.e., spin systems with RKKY-like interaction). The theoretical analysis of such idealized Hamiltonians will motivate crystal growers and provide theoretical guidance for experimentalists to discover new multi-orbital-based low-dimensional compounds that may display highly unusual physics.
