Abstract

We consider the evolution of superfluid properties of a three dimensional p-wave Fermi gas from weak (BCS) to strong (BEC) coupling as a function of scattering volume. We analyse the order parameter, quasi-particle excitation spectrum, chemical potential, average Cooper pair size and the momentum distribution in the ground state (T=0T = 0). We also discuss the critical temperature TcT_{\rm c}, chemical potential and number of unbound, scattering and bound fermions in the normal state (T=TcT = T_{\rm c}). Lastly, we derive the time-dependent Ginzburg-Landau equation for TTcT \approx T_{\rm c} and extract the Ginzburg-Landau coherence length.
