  • Microscopic description of relaxation of impurity magnetic atoms in spiral magnetics 
    Ivashin, A.P. (Вопросы атомной науки и техники, 2001)
    Kinetics of the impurity magnetic atoms in spiral magnetic is researched. The spectrum of the excitations of the impurity spin is obtained in approximation of weakly coupling. The equation for impurity density matrix up ...
  • Modulation instability in two component Bose-Einstein condensate with relative component motion 
    Ivashin, A.P.; Marinenko, E.D. (Вопросы атомной науки и техники, 2019)
    The development of modulation instability in a spatially homogeneous two-component Bose-Einstein condensate (BEC), in which the interacting components move through each other at a relative speed, is investigated. It is ...
  • 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 ...
  • On equilibrium states of superfluid with d-wave pairing 
    Ivashin, A.P.; Kovalevsky, M.Y.; Chekanova, N.N. (Вопросы атомной науки и техники, 2002)
    The equilibrium states of quantum fluid with d-pairing classification is carried out on the basis of the quasiaverages concept. It is shown, that the set of such an equilibrium states can be classified in the terms of the ...
  • 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 ...
