Abstract

We have evaluated the density-density static response of the electrongas at zero temperature and in the metallic regime by diffusion MonteCarlo. The computed local field factor G(q) smoothly interpolates between the asymptotic small and large q behavior, with a crossover around 2q(F). In fact, G(q) appears to be almost completely given by its asymptotes, being accurately reproduced by the local density approximation to density functional theory for q less than or similar to 2q(F). We give a simple formula to reproduce G(q) at relevant values of the wave vector.
