Exotic superfluid states of lattice fermions in elongated traps
arXiv:1009.5676 · doi:10.1103/PhysRevLett.106.095301
Abstract
We present real-space dynamical mean-field theory calculations for attractively interacting fermions in three-dimensional lattices with elongated traps. The critical polarization is found to be 0.8, regardless of the trap elongation. Below the critical polarization, we find unconventional superfluid structures where the polarized superfluid and Fulde-Ferrell-Larkin-Ovchinnikov-type states emerge across the entire core region.
