Superfluid Pairing in the Three Component Fermi Gas
Abstract
We present an analysis of the SU(3) symmetric model of the strongly interacting three component Fermi gas in the continuum space using quantum Monte Carlo techniques. Three body effects predominate in the regime of interaction strength beyond that of threshold of the three particle bound state. However, we find that there is an interval of the interaction strength where the SU(2)(1) broken symmetry superfluidity is possible. For a strong enough interaction, the SU(3) symmetry is restored and the superfluidity is suppressed. Within the interval of the broken symmetry, we also find that on average the particle pairs belonging to the species with superfluid pairing remain further separated than those without the superfluid pairing correlation.
