  • Density of states of interacting two-level systems in amorphous solids in the mean random field approximation 
    Borisenko, A.A. (Вопросы атомной науки и техники, 2007)
    The mean random field approach [1,2] is generalized to the case of random (with certain distribution) values of tunneling matrix elements and double-well potential asymmetries and applied to account for the dipole interaction ...
  • Dynamic theory of condensed matters with internal structure 
    Kovalevsky, M.Yu.; Logvinova, L.V.; Matskevych, V.T. (Вопросы атомной науки и техники, 2007)
    The results of investigations of condensed matters with internal structures are presented. Additional macroscopic parameters connected with this internal structure in the case of uniaxial and biaxial nematic liquid crystals ...
  • Finite size induced phenomena in 2D classical spin models 
    Kapikranian, O.; Berche, B.; Holovatch, Yu. (Вопросы атомной науки и техники, 2007)
    We make a short overview of the recent analytic and numerical studies of the classical two-dimensional XY and Heisenberg models at low temperatures. Special attention is being paid to an influence of finite system size L ...
  • Impurity-impurity pair correlation function and paramagnetic-to-ferromagnetic transition in the random Ising model 
    Ivaneyko, D.; Berche, B.; Holovatch, Yu.; Ilnytskyi, Ja. (Вопросы атомной науки и техники, 2007)
    In this Monte Carlo study we concentrated on the influence of non-magnetic impurities arranged as the lines with random orientation on paramagnetic-to-ferromagnetic phase transition in the 3D Ising model. Special emphasize ...
  • Modeling the precipitation kinetics in systems with strong heterophase fluctuations 
    Turkin, A.A.; Bakai, A.S. (Вопросы атомной науки и техники, 2007)
    The hierarchy of the Becker-Döring rate equations is used to consider the influence of heterophase fluctuations on the kinetics of precipitation in supersaturated solid solutions, including the nucleation stage and the ...
  • Molecular dynamics simulation of phase transitions in liquid carbon 
    Byshkin, M.S.; Bakai, A.S.; Turkin, A.A. (Вопросы атомной науки и техники, 2007)
    Thermodynamic properties and phase transformations in amorphous carbon and in supercooled liquid carbon are studied by the method of molecular dynamics (MD). The dependence of the diamond melting temperature on pressure ...
  • Quantum nature of non-Fermi charge carriers for pseudogap state of high-Tc superconductors 
    Sergeeva, G.G. (Вопросы атомной науки и техники, 2007)
    For pseudogap state of underdoped cuprates high temperature superconductors (HTS) with stripe structure of copper-oxygen plane an approach for describing of U-stripe as two-dimensional state with vortex-like excitations ...
  • Spontaneous symmetry breaking in the theory of modulated structures 
    Babich, A.V.; Berezovsky, S.V.; Klepikov, V.F. (Вопросы атомной науки и техники, 2007)
    The parametrical evolution of the one-component order parameter under the spontaneous symmetry breaking in the Michelson model is considered. A critical behavior of a system with the critical point which has the properties ...
  • The ideal gas of hydrogen-like atoms response to the perturbation by the external electromagnetic field 
    Slyusarenko, Yu.V.; Sotnikov, A.G. (Вопросы атомной науки и техники, 2007)
    The response of the ideal gas consisting of hydrogen-like atoms to the perturbation by the external electromagnetic field in low temperature region is studied. Consideration is based on using the Green functions formalism ...
  • Transient kinetics of homogeneous nucleation 
    Fateev, M.P. (Вопросы атомной науки и техники, 2007)
    The transient stage of nucleation is studied on the basis of the Fokker-Planck equation. The approximate self-similar solutions for the nucleus size distribution function and the nucleation rate are obtained. The non-diffusion ...
