讨论了全息生成光势在研究超冷原子超流动性中的适用性。通过使用空间光调制器和反馈算法，我们生成了一个具有可变明亮区域的光滑环，该环可以动态旋转以搅拌超冷原子并诱导超流。我们还评论了它未来与冷原子实验的结合。
We discuss the suitability of holographically generated optical potentials for the investigation of superfluidity in ultracold atoms. By using a spatial light modulator and a feedback enabled algorithm, we generate a smooth ring with variable bright regions that can be dynamically rotated to stir ultracold atoms and induce superflow. We also comment on its future integration into a cold atom experiment.
