论文摘要
我们建议通过通过公共腔模式和双重泵激光器启用的两个非谐波拉曼过渡途径的组合来控制旋转原子气体的旋转动力学。与合成的自旋交换强度成正比的混合速率以及有效的原子二次Zeeman偏移（QZS）都可以通过更改泵激光参数来调整。与基于固有的旋转交流碰撞相互作用相比，原子集体旋转的淬火和驱动动力学在时间尺度上可以控制更快。我们提出的结果为探索当前实验中可访问的原子集合物理学的旋转物理学打开了有希望的途径。
We propose to control spin-mixing dynamics in a gas of spinor atoms, via the combination of two off-resonant Raman transition pathways, enabled by a common cavity mode and a bichromatic pump laser. The mixing rate, which is proportional to the synthesized spin-exchange interaction strength, and the effective atomic quadratic Zeeman shift (QZS), can both be tuned by changing the pump laser parameters. Quench and driving dynamics of the atomic collective spin are shown to be controllable on a faster time scale than in existing experiments based on inherent spin-exchange collision interactions. The results we present open a promising avenue for exploring spin-mixing physics of atomic ensembles accessible in current experiments.
