research interest

Strongly correlated multi-orbital systems Past experience in strongly correlated quantum systems, especially Cu-based materials, showed that the high-temperature superconductivity is closely connected to a bad-metal state and a nearby antiferromagnetic order. As such, there has been a considerable effort devoted to the understanding of the electron correlation effects and the associated magnetism. On the other hand, the multi-orbital system properties, relevant for Fe-based materials, are much less explored. Iron-based superconductors display various phases originating in the multi-orbital nature of iron itself, and as a consequence, in the competition between electronic, orbital, and spin degrees of freedom. Prominent among these novel effects is the orbital-selective Mott phase (OSMP), where electronic correlations cause a unique mixture of metallic and insulating behaviour.

Our group investigates (primarily using numerical techniques) static and dynamic properties of multi-orbital systems with the emphasis on its magnetic properties and the role of Hund’s coupling. One can expect that the competition of the latter and Coulomb interaction can lead to a novel type of frustrated magnetism. Furthermore, a nontrivial magnetic order within OSMP could lead to nontrivial topological effects.

Transport properties in low-dimensional quantum systems Transport in many-body systems of interacting fermions established several novel - entirely quantum - aspects going well beyond usual weak-scattering or Boltzmann-type approaches to transport. Such behaviour is especially pronounced in the system with reduced dimensionality (e.g., in 1D chains and quasi-1D ladders). Furthermore, due to the possibility of accurate treatment on the latter, the low-dimensional systems have become a playground for condensed-matter physicists to test various theoretical scenarios. A prominent fundamental model and an experimentally relevant example of such a phenomenon is the one-dimensional antiferromagnetic Heisenberg model describing the low-dimensional quantum magnets even at high temperatures.

We are interested in various transport properties of the low-dimensional quantum system. Our study focuses, among others, on the effects of the integrability of the model, many-body localization, the physics of random interaction exchange, non-equilibrium properties, and linear response answer of the systems to experimentally relevant perturbations.

Flocking of multi-agent dynamical systems I recently got interested in the classical multi-agent dynamical systems relevant to the collective decision-making in the biological systems, e.g., the transfer of long-range information in birds' flocks. I'm interested in the extension of the so-called inertia spin model to leaderless flocking.
