We calculate the magnetic field dependence of Rabi rates for two-photon optical Raman processes in alkali atoms. Due to a decoupling of the nuclear and electronic spins, these rates fall with increasing field. At the typical magnetic fields of alkali atom Feshbach resonances (B\sim 200G-1200G), the Raman rates have the same order of magnitude as their zero field values, suggesting one can combine Raman-induced gauge fields/spin-orbital coupling with strong Feshbach-induced interactions.

Magnetic-Field Dependence of Raman Coupling Strength in Ultracold $^{40}$K Atomic Fermi Gas
We experimentally demonstrate the relation of Raman coupling strength with the external bias magnetic field in degenerate Fermi gas of 40K atoms. Two Raman lasers couple two Zeeman energy levels,
Spin-exchange-induced spin-orbit coupling in a superfluid mixture
We investigate the ground-state properties of a dual-species spin-1/2 Bose-Einstein condensate. One of the species is subjected to a pair of Raman laser beams that induces spin-orbit (SO) coupling,
Recent advances in spin-orbit coupled quantum gases
Abstract In this topical review, we discuss the recent advances in the study of spin-orbit coupled quantum gases. Spin-orbit coupling (SOC) locks a particle's spin with its momentum and it is one of

Spin-exchange-induced exotic superfluids in a Bose-Fermi spinor mixture
We consider a mixture of spin-1/2 bosons and fermions, where only the bosons are subjected to the spin-orbit coupling induced by Raman beams. The fermions, although not directly coupled to the Raman
