Fulde-Ferrell-Larkin-Ovchinnikov pairing states between $s$- and $p$-orbital fermions

Shu-Yang Wang, Jing-Wei Jiang, Yue-Ran Shi +2

We study pairing states in an largely imbalanced two-component Fermi gas loaded in an anisotropic two-dimensional optical lattice, where the spin up and spin down fermions filled t…
