Abstract
We derive approximate expressions for the static local-field factors of a spin-polarized two-dimensional electron gas that smoothly interpolate between their small- and large-wave-vector asymptotic limits. The proposed analytical expressions reproduce recent diffusion Monte Carlo data for the unpolarized and fully polarized electron gas. We find that the degree of spin polarization produces important modifications to the local factors of the minority spins, while the local-field functions of the majority spins are less affected.
