  • Lattice Model of Intercalation 
    Mysakovych, T.S.; Krasnov, V.O.; Stasyuk, I.V. (2010)
    The thermodynamics of a lattice model of intercalation of ions in crystals is considered in the mean-field approximation (MFA). The pseudospin formalism is used for the description of the interaction of electrons with ions, ...
  • Phase diagrams of the Bose-Fermi-Hubbard model: Hubbard operator approach 
    Stasyuk, I.V.; Mysakovych, T.S.; Krasnov, V.O. (Condensed Matter Physics, 2010)
    The phase transitions in the Bose-Fermi-Hubbard model are investigated. The boson Green's function is calculated in the random phase approximation (RPA) and the formalism of the Hubbard operators is used. The regions of ...
  • Phase transitions in Bose-Fermi-Hubbard model in the heavy fermion limit: Hard-core boson approach 
    Stasyuk, I.V.; Krasnov, V.O. (Condensed Matter Physics, 2015)
    Phase transitions are investigated in the Bose-Fermi-Hubbard model in the mean field and hard-core boson approximations for the case of infinitely small fermion transfer and repulsive on-site boson-fermion interaction. The ...
  • Phase transitions in the lattice model of intercalation 
    Mysakovych, T.S.; Krasnov, V.O.; Stasyuk, I.V. (Condensed Matter Physics, 2008)
    The lattice model which can be employed for the description of intercalation of ions in crystals is considered in this work. Pseudospin formalism is used in describing the interaction of electrons with ions. The possibility of ...
  • Pseudospin-electron model spectrum in alloy analogy approximation 
    Stasyuk, I.V.; Krasnov, V.O. (Condensed Matter Physics, 2006)
    Energy spectrum of the pseudospin-electron model is investigated in the alloy analogy approximation within the framework of the dynamical mean field theory (DMFT). The case of two near Hubbard-like electron subbands, which ...
