On the theory of dynamic properties for semi--quantum fluids

V.V. Ignatyuk

On the basis of nonequilibrium statistical operator method a general theoretical framework for the study of dynamic properties of semi-quantum fluids is developed. We derive the set of equations of generalized hydrodynamics and analyse the particular case of so-called thermo-viscoelastic dynamical model of a fluid in more detail considering hydrodynamic limit. We discuss also some approximate procedures for evaluation of transport kernels which allow to obtain a closed set of equations for time correlation functions. The problem is considered in the context of relation with neutron scattering experiment data and theoretical results known previously in the literature.
