Abstract

The results of quantum Monte Carlo calculations of the ground state of dilute Fermi gases with attractive short-range two-body interactions were discussed. The strength of the interaction is varied to study different pairing regimes which are characterized by the product of the s-wave scattering length and the Fermi wave vector. The model considered consists of fermions contained in a box with periodic conditions on its boundaries. It was found that the pairing gaps and energies of superfluid Fermi gases are possible with the fixed-node Green's-function Monte Carlo (GFMC) method.
