An Evaluation of Super Fluid Density, Quasi Particle Contribution and Fluctuation Contribution as a Function of (T/Tc) for BCS-BEC Crossover Regime

L. N. Singh and L. K. Mishra

We have evaluated ratio of super fluid density to the total density (ρs/ρ), Quasi Particle Contribution (ρF n/ρ) and Fluctuation Contribution (ρB n/ρ) as a Function of (T/Tc) for three limits BCS, Pseudo gap and BEC. These results are quite useful in the study of dynamical properties in the BCS- BEC crossover region at finite temperature.
