Abstract

We study a two-dimensional two-component Fermi gas with attractive or repulsive short-range interactions at zero temperature. We use Diffusion Monte Carlo with Fixed Node approximation in order to calculate the energy per particle and the opposite spin pair distribution functions. We show the relevance of beyond mean field effects and verify the consistency of our approach by using Tan’s Contact relations.
