These equations have been numerically solved for the generalized BSk21 parametrization of the Skyrme forces in the neutron matter. The value of the splitting of the gap in the neutron energy spectrum in the superfluid neutron matter, that depends non-linearly on the density in the zero-temperature limit, have been calculated. Microscopic approach to consistent construction of the kinetic theory of low-temperature dilute gases of hydrogen-like atoms in external electromagnetic field has been developed. The system of kinetic equations for Wignerian distribution functions of free fermions of both sorts and their bound states - hydrogen-like atoms that takes into account the influence of external electromagnetic and selfconsistent (mean) fields have been obtained. Modified Gross-Pitaevski equation that takes into account dissipative function contribution have been proposed. It was applied for studying the influence of dissipative processes on the evolution of modulation instability in the two-component spacially homogeneous Bose-Einstein condensate. Maximal value of the oscillations increment has been found and the domain of existence of the modulation instability in the space of wave numbers have been determined. It has been shown that the presence of dissipation in the spacially homogeneous Bose-Einstein condensate does not influence the evolution of modulation instability and so the structure formation in it.
