Quantum theory
of electrons in solids on model and ab-initio level (electron states of
complex materials, spectral, magnetic and transport properties of
metals and semiconductors, their alloys, surfaces, interfaces and multilayers;
electron correlations, quantum critical phenomena in itinerant systems)
Nonequilibrium and transient quantum phenomena (electron dynamics in low-dimensional systems and nanostructures, quantum relaxation and decoherence, ultrafast spectroscopy)
Theory and computer simulations of complex statistical systems (formation of surface nanostructures, random and spin-glass systems, dynamical fluctuations in irreversible processes)
