我们发现，Jaynes-Cummings动力学可以观察到介观原子系综与经典电磁场相互作用的里德伯封锁制度的平均里德伯激发数在介观系综显示崩溃和复苏典型的这个模型的时间动态。由于Rydberg阻塞系综集体态之间Rabi振荡的频率依赖于相互作用原子的数量，对于随机加载的光偶极阱，我们预测了Rabi振荡的崩溃和复苏。我们研究了有限的相互作用强度和有限的激光线宽上的复苏的可见性的影响。我们已经表明，拉比振荡的崩溃和复苏的观察可以被用作一个签名的里德伯封锁，而不需要测量的确切数目的里德伯原子。
We show that Jaynes-Cummings dynamics can be observed in mesoscopic atomic ensembles interacting with a classical electromagnetic field in the regime of a Rydberg blockade where the time dynamics of the average number of Rydberg excitations in mesoscopic ensembles displays collapses and revivals typical of this model. As the frequency of Rabi oscillations between collective states of Rydberg-blockaded ensembles depends on the number of interacting atoms, for randomly loaded optical dipole traps, we predict collapses and revivals of Rabi oscillations. We have studied the effects of finite interaction strengths and a finite laser linewidth on the visibility of the revivals. We have shown that observation of collapses and revivals of Rabi oscillations can be used as a signature of the Rydberg blockade without the need to measure the exact number of Rydberg atoms.
