Thermodynamics of a Trapped Unitary Fermi Gas

Abstract

We present the first model-independent comparison of recent measurements of the entropy and of the critical temperature of a unitary Fermi gas, performed by Luo et al., with the most complete results currently available from finite temperature Monte Carlo calculations. The measurement of the critical temperature in a cold fermionic atomic cloud is consistent with a value $T_c=0.23(2)epsilo{n}_F$ in the bulk, as predicted by the present authors in their Monte Carlo calculations.
