Query: Fulde-Ferrell Pairing instability in Spin-Orbit Coupled Fermi Gas   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.
