Item Cavity-assisted dynamical spin-orbit coupling in cold atoms(American Physical Society, 2014) Dong, Lin; Zhou, Lu; Wu, Biao; Ramachandhran, B.; Pu, Han; Rice Quantum InstituteWe 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 leads to a dramatic modification of the atomic dispersion relation, and further leads to dynamical instability of the system. We propose to detect the change in the cavity photon number as a direct way to demonstrate dynamical instability.
