Parametrized equation of state for electron liquids in the SingwiTosiLandSjolander aproximation
Abstract
Results are reported of a theoretical study of an equation of state for electron liquids (onecomponent plasmas of electrons embedded in a uniform neutralizing background of positive charges), where there is an interplay between the strong Coulombcoupling effect and the degrees of Fermi degeneracy. Calculations are based on the SingwiTosiLandSjolander approximation (1968). The calculated results are parametrized in the form of analytic formulas for the interaction and excess free energies, which are applicable over a wide range of parameters as long as the electrons are in a paramagnetic fluid state. Unlike the present study, earlier studies concentrated on plasmas where the Fermi degeneracy parameter tended either to zero or to infinity, thus excluding many actual plasmas (stellar interiors, heavy planets such as Jupiter, plasmas in projected inertial confinement fusion experiments, and the liquid metals).
