Nonuniform mixed-parity superfluid state in Fermi gases
arXiv:cond-mat/0607569 · doi:10.1103/PhysRevLett.97.197003
Abstract
We study the effects of dipole interaction on the superfluidity in a homogeneous Fermi gas with population imbalance. We show that the Larkin-Ovchinnikov-Fulde-Ferrell phase is replaced by another nonuniform superfluid phase, in which the order parameter has a nonzero triplet component induced by the dipole interaction.
