Abstract
We consider finite-momentum pairing of superfluid phase in ultracold Fermi gas with spin-orbit coupling when subjected to an effective Zeeman field. Based on our two body and mean field many body calculations, we show that the Fulde-Ferrell type superfluid dominates in zero and finite temperature phase diagram. We examine the origin and properties of this novel phase systematically.
