In particular, the obtained results refer to the photoelectron emission spectra for the charge-ordered phase, the phonon contributions to resonance inelastic X-ray scattering, the thermoelectric properties of systems with nonlocal correlations, the spectra and phase diagrams of optical lattices etc. These results were obtained using such methods of the strongly correlated system theory as the dynamical mean-field theory, the Green function method, the Hubbard operator technique, cluster expansions, exact diagonalizations etc. The results of the researches during 2103-2017 are published in 159 publications.
