Thermodynamics and Correlational Properties of Finite-Temperature Electron Liquids in the Singwi-Tosi-Land-Sjölander Approximation

The dielectric formulation is applied to the study of the static correlations in the electron liquids at finite temperatures. The strong coupling effects arising from the exchange and Coulomb correlations are taken into account through the local-field correction in the Singwi-Tosi-Land-Sjölander approximation. The resulting integral equations are solved self-consistently, and the thermodynamic quantities are evaluated at various combinations of the plasma parameters in the range of the intermediate Fermi degeneracy. The results are parametrized in the form of the analytic formulas, which satisfy a number of exact boundary conditions and limiting behaviors.
