# Superfluid transition temperature and fluctuation theory of spin-orbit- and Rabi-coupled fermions with tunable interactions

@article{Powell2022SuperfluidTT, title={Superfluid transition temperature and fluctuation theory of spin-orbit- and Rabi-coupled fermions with tunable interactions}, author={P D Powell and Gordon Baym and Carlos A. R. S{\'a} de Melo}, journal={Physical Review A}, year={2022} }

We obtain the superfluid transition temperature of equal Rashba-Dresselhaus spin-orbitand Rabi-coupled Fermi superfluids, from the Bardeen-Cooper-Schrieffer (BCS) to Bose-Einstein condensate (BEC) regimes in three dimensions for tunable s-wave interactions. In the presence of Rabi coupling, we find that spin-orbit coupling enhances (reduces) the critical temperature in the BEC (BCS) limit. For fixed interactions, we show that spin-orbit coupling can convert a first-order (discontinuous) phase…
