Breached Superfluidity via P-Wave Coupling
arXiv:cond-mat/0409088 · doi:10.1103/PhysRevLett.94.110402
Abstract
Anisotropic pairing between fermion species with different fermi momenta opens two-dimensional areas of gapless excitations, thus producing a spatially homogeneous state with coexisting superfluid and normal fluids. This breached pairing state is stable and robust for arbitrarily small mismatch and weak p-wave coupling.
