Critical temperature for fermion pairing using lattice field theory

Abstract

Dilute gases of 2-component fermions are of great interest in atomic and nuclear physics. When interactions are strong enough so that a bound state is at threshold, universal behavior is expected. Lattice field theory provides a first principles approach to the study of strongly interacting systems such as this through Monte Carlo simulation. Results of exploratory simulations are presented here. In particular, the finite temperature phase transition between superfluid and normal states is studied. We present first results for the critical temperature T_c and describe the future work necessary to determine T_c as a function of interaction strength.
