Findings

Trap anisotropy significantly influences heat capacity near the transition.

Transition temperature depends on trap aspect ratio.

Heat capacity behavior varies with trap geometry.

Abstract

We investigate mean-field effects in two- component trapped Fermi gases in the superfluid phase, in the vicinity of s-wave Feshbach resonances. Within the resonance superfluidity approach (Holland et al., 2001) we calculate the ground state energy and the heat capacity as function of temperature. Heat capacity is analyzed for different trap aspect ratios. We find that trap anisotropy is an important factor in determining both the value of heat capacity near the transition temperature and the transition temperature itself.
