Essay

Object of investigations: pseudospin-electron model. Aim: investigation of thermodynamics of pseudospin-electron model. Methods: Green functions, diagram technique, generalized random phase approximation. Results: The phase transitions and phase separations, caused by direct as well as effective interaction between pseudospins, are investigated. The two-sublattice pseudospin-electron model is proposed. It can be used for description of instabilities in YBaCuO-type superconductors. Implementation: scientific publications. Application: theory of strongly correlated electron systems.
