Fulde-Ferrell-Larkin-Ovchinnikov pairing in one-dimensional optical lattices
Fulde-Ferrell-Larkin-Ovchinnikov pairing in one-dimensional optical lattices
Spin-polarized attractive Fermi gases in one-dimensional (1D) optical lattices are expected to be remarkably good candidates for the observation of the Fulde-Ferrell-Larkin-Ovchinnikov (FFLO) phase. We model these systems with an attractive Hubbard model with population imbalance. By means of the density-matrix renormalization-group method, we compute the pairing correlations as well …
