论文摘要
我们报告了冷$^{87} $ rb原子在迪克（Dicke）在迪克（Dicke）方向上运行的大量原子的密集团体中的次级观察，其尺寸小于过渡波长。我们验证原子数是唯一管理次级的合作参数。我们探究了多体制中的动力学，并支持图片，即多次激发的子亚基态被构建为独立衰减的单个偏态状态的叠加。此外，我们实施了一个实验程序，以释放以光脉冲中持续的模式中存储的激发。该技术是朝着基于次级量化的量身定制的光储存的第一步。
We report the observation of subradiance in dense ensembles of cold $^{87}$Rb atoms operating near Dicke's regime of a large number of atoms in a volume with dimensions smaller than the transition wavelength. We validate that the atom number is the only cooperativity parameter governing subradiance. We probe the dynamics in the many-body regime and support the picture that multiply-excited subradiant states are built as a superposition of singly-excited states that decay independently. Moreover, we implement an experimental procedure to release the excitation stored in the long-lived modes in a pulse of light. This technique is a first step towards the realization of tailored light storing based on subradiance.
