提出了一种利用驻波和行波产生光学腔中凝聚态自旋轨道耦合的新方案。结果表明，激光与腔的相互作用产生了丰富的量子相。我们的方案也产生了一个大的合成磁场的自旋态，这可能有助于研究量子霍尔效应在超冷原子气体。
We propose a novel scheme to generate the spin-orbit coupling for a condensate placed inside an optical cavity by using a standing wave and a traveling wave. It is shown that the interplay of the laser lights and the cavity gives rise to rich quantum phases. Our scheme also generates a large synthetic magnetic field for the dressed spin state, which may facilitate the study of the quantum Hall effect in ultracold atomic gases.
