Diamagnetism of a Dense Electron Gas

Abstract

The theory of Coulomb interactions in a dense electron gas at zero temperature is formally simplified by the introduction of an equivalent Hamiltonian which gives the correct high-density value for the correlation energy. In the corresponding approximation, the diamagnetism of a dense electron gas is found to be the same as that of noninteracting electrons. Coupling with longitudinal sound waves, or a periodic potential, fails to produce a Meissner effect.
