Our activities are focused on microscopic theories describing physical phenomena in selected families of transition metal oxides. We are interested mainly in phenomena related to the strongly correlated nature of valence electrons in these compounds that manifests itself e.g. in peculiar magnetic properties or unconventional superconductivity. These phenomena can be captured at the level of effective models such as the Hubbard model, t-J model or spin models that we deal with using a number of methods ranging from analytical diagrammatic approaches up to extensive numerical simulations performed on supercomputers.
Within the broad field of transition metal oxides, we have long-time experience with the following particular areas:
Optical response of high-Tc cuprate superconductors and related materials
Highly frustrated magnetism of honeycomb oxides with strong spin-orbit coupling
Spin-state crossover physics and excitonic condensation
Analytical approaches mainly of diagrammatic nature
Numerical exact diagonalization of small systems
Quantum Monte Carlo
Dynamical mean field theory
