  • 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 diagrams of the Bose-Hubbard model at finite temperature 
    Stasyuk, I.V.; Mysakovych, T.S. (Condensed Matter Physics, 2009)
    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 Hubbard operators is used. The regions of existence ...
  • Phase transitions in the lattice model of intercalation

    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 at weak coupling 
    Stasyuk, I.V.; Mysakovych, T.S. (Condensed Matter Physics, 2002)
    The static and dynamic dielectric susceptibility of the pseudospin-electron model is investigated in the random phase approximation. The possibility of the phase transition to the homogeneous phase, to the phase with ...
  • Raman light scattering for systems with strong short-range interaction 
    Stasyuk, I.V.; Mysakovych, T.S. (Condensed Matter Physics, 2000)
    Various type contributions to Raman light scattering are investigated for the Hubbard, t − J and pseudospin-electron models. To construct the polarizability operator the microscopic approach is used, which is based on ...
  • Raman light scattering in pseudospin-electron model at strong pseudospin-electron interaction 
    Mysakovych, T.S.; Stasyuk, I.V. (Condensed Matter Physics, 2004)
    Anharmonic phonon contributions to Raman scattering in locally anharmonic crystal systems in the framework of the pseudospin-electron model with tunneling splitting of levels are investigated. The case of strong pseud ...
