  • Charge-symmetric description of electrons and positrons in the Dirac theory without negative energies 
    Poluektov, Yu.M. (Вопросы атомной науки и техники, 2020)
    A formulation of the Dirac theory, symmetric with respect to particles and antiparticles, in which negative energy states are excluded, is proposed. Fields of particles and antiparticles are associated with wave functions ...
  • 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 ...
  • 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 ...
  • On electric polarization of helium atoms by acceleration 
    Poluektov, Yu.M.; Savchenko, V.N. (Вопросы атомной науки и техники, 2012)
    Possibility of explanation of high electric activity in superfluid helium [1–3] by polarization of helium atoms caused by acceleration is researched. It is shown that this effect is insufficient to explain the phenomenon.
  • On the microscopic theory of non-dissipative flows in Bose systems 
    Ivashin, A.P.; Poluektov, Yu.M. (Вопросы атомной науки и техники, 2007)
    The states with non-dissipative flows are explored within a microscopic approach to a problem of spatially inhomogeneous multiparticle Bose-systems. Density of superfluid component was evaluated and its correlation with ...
  • Role of single-particle and pair condensates in Bose systems with arbitrary intensity of interaction 
    Peletminskii, A.S.; Peletminskii, S.V.; Poluektov, Yu.M. (Condensed Matter Physics, 2013)
    We study a superfluid Bose system with single-particle and pair condensates on the basis of a half-phenomenological theory of a Bose liquid not involving the weakness of interparticle interaction. The coupled equations ...
  • The self-consistent field model for Fermi systems with account of three-body interactions 
    Poluektov, Yu.M.; Soroka, A.A.; Shulga, S.N. (Condensed Matter Physics, 2015)
    On the basis of a microscopic model of self-consistent field, the thermodynamics of the many-particle Fermi system at finite temperatures with account of three-body interactions is built and the quasiparticle equations of ...
  • To the theory of spatially nonuniform Bose systems with broken symmetry 
    Poluektov, Yu.M. (Вопросы атомной науки и техники, 2001)
    The model of the self-consistent field for spatially nonuniform many-particle Bose-systems with broken symmetry is constructed. The self-consistent coupled equations for wave functions of the quasiparticles and of the ...
