Scientific area of interest:
My primary research interests are in the field of statistical physics and condensed matter theory with the main focus laid on analytical treatment of lattice-statistical models such as the Ising model, the Heisenberg model, the vertex models and the lattice-statistical models of liquid mixtures. More precisely, I am interested in classical and quantum spin models in the theory of magnetism, exactly solvable models in statistical mechanics, phase separation theory, phase transitions and critical phenomena.
