研究了超导腔中单里德伯原子与单模电磁场相互作用的动力学。采用速度选择原子，观察了原子反转作为原子交换能和场交换能的演化。首次用实验证明了詹尼斯-卡明斯模型所预测的量子坍缩和量子复兴。对原子动态行为的评估使我们能够确定腔中少数光子的统计量。
The dynamics of the interaction of a single Rydberg atom with a single mode of an electromagnetic field in a superconducting cavity was investigated. Velocity-selected atoms were used and the evolution of the atomic inversion as atom and field exchange energy was observed. The quantum collapse and revival predicted by the Jaynes-Cummings model were demonstrated experimentally for the first time. The evaluation of the dynamic behavior of the atoms allows us to determine the statistics of the few photons in the cavity.
