Correlation energy of a spin-polarized electron gas at high density
Abstract
This paper extends the result of Gell-Mann and Brueckner to include spin polarization. The contributions to the correlation energy of a spin-polarized electron gas that do not vanish in the high-density limit are evaluated exactly. In the process a closed-form expression is given for the generalization of an integral that has previously been evaluated numerically.
