popup.description1
Conducting research on clarifying the role of interparticle correlations, competition of various types of interactions, quantum and temperature fluctuations in different dimensions on the observed properties of a number of macroscopic systems; study of optical spectra, including resonant inelastic scattering of light and x-rays in strongly correlated electronic systems both in equilibrium and in the presence of injection pulses.
popup.description2
The theory of equilibrium and non-equilibrium properties of strongly correlated electronic systems (correlated transport effects, x-ray photoelectron emission, resonant inelastic scattering of x-rays and combined time-resolved light scattering) is developed. The theory of field effects of the SPS family and the theory of thermodynamic properties of the S = 1/2 Heisenberg model on the pyrochlore lattice are developed. The concept of localized magnons is applied to the calculation of entanglement of quantum states and the analysis of the magnetoelectric effect in “free-fermion” spin models. The theory of polarization of the ferroelectric squaric acid crystal is constructed.
