@article{ISI:000324139300009, abstract = {Recent experiments on fermions in synthetic gauge fields result in systems with a spin-orbit coupling along one spatial axis, a detuning field, and a Zeeman field. We show theoretically that the presence of all three results in interesting and unusual phenomena in a system of interacting fermions (interactions described by a scattering length). For two fermions, bound states appear only over a certain range of the center-of-mass momenta. The deepest bound state appears at a nonzero center-of-mass momentum. For center-of-mass momenta without a bound state, the gauge field induces a resonance-like feature in the scattering continuum resulting in a large scattering phase shift. In the case of many particles, we demonstrate that the system, in a parameter range, shows flow-enhanced pairing, i.e., a Fulde-Farrell-Larkin-Ovchnnikov superfluid state made of robust pairs with a finite center-of-mass momentum. Yet another regime of parameters offers the opportunity to study strongly interacting normal states of spin-orbit-coupled fermionic systems utilizing the resonance-like feature induced by the synthetic gauge field.}, article-number = {033609}, author = {Shenoy, Vijay B.}, doi = {10.1103/PhysRevA.88.033609}, eissn = {1094-1622}, issn = {1050-2947}, journal = {PHYSICAL REVIEW A}, month = {SEP 9}, number = {3}, times-cited = {24}, title = {Flow-enhanced pairing and other unusual effects in Fermi gases in synthetic gauge fields}, unique-id = {ISI:000324139300009}, volume = {88}, year = {2013} }
