论文摘要
我们通过实验研究了一个单个Rydberg Superatom的集体衰变，该衰减是由成千上万个单独的原子组成的合奏，仅由于Rydberg封锁而仅支持一次激发。我们没有观察到由集体耦合强度与驾驶场确定的恒定衰减速率，而是表明单个存储光子的发射增强到耦合光学模式的正向方向上取决于衰减前超级答案的动力学。我们发现，观察到的衰减速率是通过超级原子的扩展模型复制的，该模型包括集体明亮状态和亚基状态之间的相干耦合。
We experimentally investigate the collective decay of a single Rydberg superatom, formed by an ensemble of thousands of individual atoms supporting only a single excitation due to the Rydberg blockade. Instead of observing a constant decay rate determined by the collective coupling strength to the driving field, we show that the enhanced emission of the single stored photon into the forward direction of the coupled optical mode depends on the dynamics of the superatom before the decay. We find that the observed decay rates are reproduced by an expanded model of the superatom which includes coherent coupling between the collective bright state and subradiant states.
