N2 - We study a non-equilibrium unitary Fermi gas, being coupled with two baths with different values of chemical potential. Extending a T-matrix approximation developed in equilibrium Fermi gases to the non-equilibrium steady state by using the Keldysh Green’s function technique, we examine the superfluid phase transition out of equilibrium. We also clarify non-equilibrium effects on the pseudogap phenomenon by strong pairing fluctuations.
