Phase diagrams of the Bose-Hubbard model at finite temperature
I. V. Stasyuk, T. S. Mysakovych
The phase transitions in the Bose-Hubbard model are investigated. A single-particle Green's function is calculated in the random phase approximation and the formalism of the Hubbar…

A Lattice Model of Intercalation
T. S. Mysakovych, V. O. Krasnov, I. V. Stasyuk
The thermodynamics of the lattice model of intercalation of ions in crystals is considered in the mean field approximation. Pseudospin formalism is used for the description of inte…
