Theory of a relativistic nuclear fluid coupled to classical fields

Abstract

Starting from the relativistic time-dependent Hartree-Fock approximation, the relativistic hydrodynamical equations coupled to a classical scalar field are derived. The pressure and stress tensors get defined automatically with the assumption of a local density approximation. In various approximations, the authors' equations reduce to those studied in the literature and the calculated sound velocity is precisely the same as that of other authors.
