Spin polarization of the lowdensity threedimensional electron gas
Abstract
To determine the state of spin polarization of the threedimensional electron gas at very low densities and zero temperature, we calculate the energy versus spin polarization using diffusion quantum Monte Carlo methods with backflow wave functions and twist averaged boundary conditions. We find a secondorder phase transition to a partially polarized phase at r_{s}~50+/2. The magnetic transition temperature is estimated using an effective meanfield method, the Stoner model.
