Superfluid properties of atomic 6Li in a magnetic trap

Abstract

Recently we showed that a homogenous gas of spin-polarized 6Li atoms can become superfluid at experimentally attainable temperatures and densities. Moreover we showed that the lifetime of the gas can be sufficiently long to perform experiments. The critical temperature depends on the densities of the two hyperfine states involved. Here we present a theory for the superfluid state for arbitrary ratios of these densities.
