Theory of Fermionic superfluid with SU(2)xSU(6) symmetry
arXiv:1101.1714 · doi:10.1103/PhysRevA.83.063607
Abstract
We study theoretically interspecies Cooper pairing in a fermionic system with SU(2)xSU(6) sym- metry. We show that, with suitable unitary transformations, the order parameter for the ground state can be reduced to only two non-vanishing complex components. The ground state has a large degeneracy. We find that while some Goldstone modes have linear dispersions, others are quadratic at low frequencies. We compare our results with the case of SU(N).
