  • On the long wave fluctuations in systems of particles interacting with hydrodynamic media 
    Nikolayenko, S.O.; Slyusarenko, Yu.V. (Вопросы атомной науки и техники, 2012)
    Our work offers a stochastic approach for description of long wave fluctuations in systems of particles interacting with hydrodynamic media. The presence of long-wave fluctuations in the system is caused by the random ...
  • Gaussian fluctuation field of electrical polarization in strongly heated dielectric media 
    Virchenko, Yu.P.; Saprykin, M.A. (Вопросы атомной науки и техники, 2012)
    The spatially nonuniform gaussian random field which describes fluctuations of electrical polarization in dielectric medium is built. It is done for the case when the space temperature distribution exists. This filed is ...

    Brodskii, R.Ye.; Virchenko, Yu.P. (Вопросы атомной науки и техники, 2012)
    The process of slow material fragmentation is studied when the diffusion approximation is applicable. Final distribution density of fragment sizes is calculated in the case of scale-homogeneity of subdivision mechanism.

    Ispirian, K.A. (Вопросы атомной науки и техники, 2012)
    After a short discussion on the physics of the Unruh effect, Hawking, Larmor and Unruh radiations we consider some experiments proposed up to 2008, which can be carried out with the help of high energy electron and optical ...
  • Proposals for the study of UNRUH (effect) radiation with the help of entangled photons produced in electron-photon collisions 
    Ispirian, K.A. (Вопросы атомной науки и техники, 2012)
    We consider some experiments proposed after 2006, which can be carried out with the help of high energy electron and powerful laser or X-ray photon beams.
  • On the hydrodynamics of polaron gas in the Bogolyubov reduced description method 
    Sokolovsky, S.A. (Вопросы атомной науки и техники, 2012)
    On the basis of a generalization of the Chapman-Enskog method a new approach to derivation of hydrodynamic equations for weak density polaron gas has been elaborated taking into account the relaxation of temperature and ...
  • Polarization features of acoustic spectra in uniaxial and biaxial nematic liquid crystals 
    Kovalevsky, M.Y.; Logvinova, L.V.; Matskevych, V.T. (Вопросы атомной науки и техники, 2012)
    The results of investigation of uniaxial and biaxial nematic liquid crystals dynamics with molecules of the various forms are presented. These condensed matters possess internal spatial anisotropy and for their adequate ...
  • Low-frequency green functions asymptotics in uniaxial and biaxial nematic liquid crystals 
    Matskevych, V.T. (Вопросы атомной науки и техники, 2012)
    Uniaxial and biaxial nematic liquid crystals are examples of the complicated condensed matters possessing an internal microstructure shown on macroscopic level in the form of a number of the physical phenomena and processes. ...
  • To the Landau theory of relaxation phenomena in plasma 
    Sokolovsky, A.I.; Gorev, V.N.; Chelbaevsky, Z.Yu. (Вопросы атомной науки и техники, 2012)
    The distribution function of quasi-equilibrium plasma in linear approximation in differences of temperatures and velocities of its components has been obtained. It was done on the basis of our generalization of the ...
  • Domain of applicability of various approaches to description of electromagnetic field in medium 
    Lyagushyn, S.F.; Sokolovsky, A.I.; Salyuk, Yu.M. (Вопросы атомной науки и техники, 2012)
    The problem of parameters, which are necessary for nonequilibrium electromagnetic field description, is investigated on the basis of the Bogolyubov reduced description method establishing the necessity of binary correlations ...
  • Extension of the Sp(2,C) group for description of a three-body system 
    Yaroshenko, A.P.; Uvarov, I.V. (Вопросы атомной науки и техники, 2012)
    We propose a new approach to the three-body problem that is based on the extension of the Sp(2,C) group, which is the universal covering group for the Lorentz group, to the Sp(4,C) one. Angular momenta of the particles in ...
  • Nonperturbative approach to superfluid bose systems 
    Peletminskii, A.S.; Peletminskii, S.V.; Poluektov, Yu.M. (Вопросы атомной науки и техники, 2012)
    We study a superfluid Bose system with single-particle and pair condensates using a nonperturbative approach. The self-consistency equations for two order parameters are obtained from the principle of maximum entropy. They ...
  • Phonons, rotons and ripplons at interfaces 
    Tanatarov, I.V.; Adamenko, I.N.; Nemchenko, K.E.; Wyatt, A.F.G. (Вопросы атомной науки и техники, 2012)
    We use dispersive hydrodynamics to describe thermal excitations of superfluid helium 4. Dispersion relation of the bulk quasiparticles, phonons and rotons, acts as an input parameter of the theory. Wiener and Hopf method ...
  • Nonlocal effect influence on the vortex filament structure in Bose-gas 
    Ivashin, A.P.; Poluektov, Yu.M. (Вопросы атомной науки и техники, 2012)
    Using the Gross-Pitaevskii equation (GPE), which accounts for a weak non-locality effects, we study the structure of the vortex filaments in a Bose-gas. We show that the sign of the additional terms in the generalized GPE ...
  • Critical phenomena and critical dimensions in anisotropic nonlinear systems 
    Babich, A.V.; Berezovsky, S.V.; Kitcenko, L.N.; Klepikov, V.F. (Вопросы атомной науки и техники, 2012)
    The model that allows one to generalize the notions of the multicritical and Lifshitz points is considered. The model under consideration includes the higher powers and derivatives of order parameters. Critical phenomena ...
  • The limit solubility relationships based on Frenkel’s heterophase fluctuations theory 
    Shapovalov, R.V.; Osmayev, O.A. (Вопросы атомной науки и техники, 2012)
    For a weak one-component solution, in which the solvent and dissolved substances are not chemically bound, a simple analytical approximation was found for temperature dependence of limiting solubility of the dissolve ...
