  • Heat capacity and spin susceptibility of two-dimensional t–J model 
    Antsygina, T.N.; Poltavskaya, M.I.; Poltavsky, I.I.; Chishko, K.A. (Физика низких температур, 2007)
    Thermodynamic properties of the t–J model on square and triangular lattices near half-filling are investigated theoretically within an analytical approach based on the Kondo and Yamaji’s Green function decoupling scheme. ...
  • Helium atom in an external electric field: Exact diagonalization 
    Antsygina, T.N.; Chishko, K.A. (Физика низких температур, 2014)
    An exact diagonalization method is applied to solve the quantum-mechanical problem of spinless helium atom in an external electric field of arbitrary magnitude. The basis set for two-electron problem is built from different ...
  • Lattice distortion of quantum cryocrystals under pressure 
    Tretyak, S.M.; Antsygina, T.N.; Freiman, Yu.A. (Физика низких температур, 2006)
    The hcp lattice distortion parameter δ, the deviation of c/a ratio from the ideal hcp value √ 8/3 , have been calculated for solid He under pressure taking into account two- and three-body interatomic forces. The resulting ...
  • Structural evolution of ferromagnetic ³He multilayers adsorbed on exfoliated graphite 
    Antsygina, T.N.; Chishko, K.A. (Физика низких температур, 2013)
    On the basis of our theoretical results describing two-dimensional spin-1/2 Heisenberg model in an external magnetic field we analyze and interpret known from literature experimental data on magnetization of pure ...
  • Translational-rotational interaction in dynamics and thermodynamics of 2D atomic crystal with molecular impurity 
    Antsygina, T.N.; Poltavskaya, M.I.; Chishko, K.A. (Физика низких температур, 2003)
    The interaction between the rotational degrees of freedom of a diatomic molecular impurity and the phonon excitations of a two-dimensional atomic matrix commensurate with a substrate is investigated theoretically. It is ...
