我们报告了里德伯原子实验，展示了由谐振外场驱动的谐振微波腔中自发发射的动态抑制。如果注入场的拉比频率大于原子和腔线宽，则由于莫洛三重态的边带频率处的场波动受到抑制，原子几乎完全与腔模式解耦。这是通过腔内大约 100 个微波光子实现的。衰减率降低是有限腔响应时间引起的非马尔可夫动力学的结果
We report a Rydberg-atom experiment, demonstrating the dynamic suppression of spontaneous emission in a resonant microwave cavity driven by a resonant external field. If the Rabi frequency of the injected field is larger than the atomic and cavity line widths, the atoms almost completely decouple from the cavity mode due to suppressed field fluctuations at the sideband frequencies of the Mollow triplet. This was achieved with about 100 microwave photons in the cavity. The reduced decay rate is a consequence of non-Markovian dynamics induced by the finite cavity-response time
