"Cavity-assisted dynamical spin-orbit coupling in cold atoms." <i>Physical Review A,</i> 89, no. 1 (2014) American Physical Society: https://doi.org/10.1103/PhysRevA.89.011602.https://hdl.handle.net/1911/94839We 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.engArticle is made available in accordance with the publisher's policy and may be subject to US copyright law.
