Cavity-assisted dynamical spin-orbit coupling in cold atoms
Cavity-assisted dynamical spin-orbit coupling in cold atoms
We consider ultracold atoms subjected to a cavity-assisted two-photon Raman transition. The Raman coupling gives rise to effective spin-orbit interaction which couples the atom's center-of-mass motion to its pseudospin degrees of freedom. Meanwhile, the cavity photon field is dynamically affected by the atom. This feedback between the atom and photons …
