Abstract

Cold, dense gases of fermions offer exciting new opportunities for fundamental studies of quantum degeneracy, collective behavior, and superfluidity. Fermionic ⁶Li has been the subject of numerous theoretical treatments. This is due in part to its anomalously large and negative triplet scattering length, a_T = -2160 a_O, which arises from a near zero energy resonance. The large scattering length leads to two-state mixtures which are predicted to undergo a transition to a superfluid state at a relatively high temperature.
