A consistent description of a kinetics and hydrodynamics of quantum Bose systems. Time correlation functions and collective exitation spectrum

P.A. Hlushak

On the basis of nonequilibrium statistical operator method the description of dynamic properties of liquid He$^4$ above $T_{\lambda }$ is being carried out. The systems of transport equations and the equations for time correlation functions are obtained. Various possibilities of the approximate evaluation of transport kernels for obtaining of the closed chain of equations are being analyzed. The problem is considered in the context of relation with neutron scattering experiment data.
