SPIN 1/2 FERMIONS IN THE UNITARY REGIME AT FINITE TEMPERATURE
Aurel Bulgac, Joaquín E. Drut, Piotr Magierski
We have performed a fully non-perturbative calculation of the thermal properties of a system of spin 1/2 fermions in 3D in the unitary regime. We have determined the critical temperature for the superfluid-normal phase transition. The thermodynamic behavior of this system presents a number of unexpected features, and we conclude that spin 1/2 fermions in the BCS-BEC crossover should be classified as a new type of superfluid.
