论文摘要
在冷原子云中形成不稳定性的光力模式导致光和原子的自组织空间结构。在这里，我们考虑在存在相结构的输入场的情况下，携带轨道角动量的冷原子云的光学机械自我结构。对于平面环腔设置，耦合腔场和原子密度方程的模型描述了横向平面中的各种漂移调制不稳定性。这导致形成了旋转的自原子晶格环。使用耦合原子和光学动力学的线性稳定性分析和数值模拟，我们证明了存在与结构化泵相曲线诱导的宏观原子传输的存在
Optomechanical pattern forming instabilities in a cloud of cold atoms lead to self-organized spatial structures of light and atoms. Here, we consider the optomechanical self-structuring of a cold atomic cloud in the presence of a phase structured input field, carrying orbital angular momentum. For a planar ring cavity setup, a model of coupled cavity field and atomic density equations describes a wide range of drifting modulation instabilities in the transverse plane. This leads to the formation of rotating self-organized rings of light-atom lattices. Using linear stability analysis and numerical simulations of the coupled atomic and optical dynamics, we demonstrate the presence of macroscopic atomic transport corresponding to the pattern rotation, induced by the structured pump phase profile
