Abstract
The ground-state properties of an electron gas at metallic densities are investigated using the Wu-Feenberg theory of Fermi liquids. The correlation energy, the low-temperature specific heat, and the spin susceptibility are computed, and the ground state is found to be paramagnetic. The perturbative correction to the correlation energy owing to the particle-hole excitations in a correlated-basis-function formulation is found to be insignificant.Keywords
