  • Effective mass of atom and the excitation spectrum in liquid helium-4 at T = 0 K 
    Rovenchak, A.A. (Физика низких температур, 2003)
    A self-consistent approach is applied for calculations within the two-time temperature Green function formalism in the random phase approximation for superfluid ⁴He. The effective mass of the ⁴He atom is computed asm m * ...
  • Thermodynamics of the Bose-system with a small number of particles 
    Vakarchuk, I.O.; Rovenchak, A.A. (Condensed Matter Physics, 2001)
    A theoretical description of the interacting Bose-system is proposed. It is based on the extrapolation of the results obtained for the systems with a small number of particles N = 2, 3, 4 , etc. to the bulk case of N = ...
