论文摘要
我们报告了Ultracold $^{87} $ rb和$^{23} $ na Atoms的自旋1混合物中异核自旋动力学的观察和操纵。动力学是由种间旋转依赖性相互作用驱动的，并显示出对磁场的明显依赖性，并受到线性和二次Zeeman偏移的影响。类似于研究良好的同核病例，可以通过用远见的微波磁场调整二次Zeeman偏移来控制种间旋转动力学。此外，我们成功地通过向量光移位实现了旋转动力学控制，该矢量光转移充当$^{87} $ rb原子上的物种选择性磁场。因此，这两种方法均表明原子的损失可忽略不计，这将是研究具有快速时间和高空间分辨率的旋转动力学的强大技术。
We report the observation and manipulation of heteronuclear spin dynamics in a spin-1 mixture of ultracold $^{87}$Rb and $^{23}$Na atoms. The dynamics is driven by the interspecies spin-dependent interaction and shows a pronounced dependence on magnetic fields with influences from both linear and quadratic Zeeman shifts. Similar to the well-studied homonuclear cases, the interspecies spin dynamics can be controlled by tuning the quadratic Zeeman shift with far-detuned microwave fields. In addition, we successfully realize spin dynamics control with vector light shifts which act as a species-selective effective magnetic field on $^{87}$Rb atoms. Both methods show negligible loss of atoms thus will be powerful techniques for investigating spin dynamics with fast temporal and high spatial resolutions.
