Abstract

We address the problem of finite size errors on the energy computed in quantum Monte Carlo simulations. We introduce a scheme based on the random phase approximation that, within a single calculation, allows to retrieve the leading order correction and produces practically converged results for modest numbers of particles. Applications to the electron gas and silicon are presented.
