论文摘要
最近已经实现了有趣的集体自发级联排放。尽管取得了很大的成功，但仍然缺乏对复杂性的深度理解。有了这一动机，这项工作开发了一种新的简单级联超级级别模型。现有的相同两级原子的模型通过新的见解重新验证。引入平均时间延迟和波动的时间演变，并以四种不同的方式获得了超沉载时间延迟。这些公式可以将两级模型扩展到级联的三级模型。相关的两模式排放和特征将详细讨论。将来，可以在量子噪声猝灭中使用集体原子的相关排放。
Intriguing collective spontaneous cascade emissions have recently been realized. In despite of much success, a depth understanding of the complexity is still lacking. With this motivation, a new simple cascade superradiance model is developed in this work. The existing model of identical two-level atoms is reexamined with a new insight. Temporal evolutions of average time delays and the fluctuations are introduced and the superradiance time delays are obtained in four different ways. These formulations allow to extend the two-level model to a cascade three-level model. The correlated two-mode emissions and the characteristics are discussed in detail. In the future, the correlated emissions from the collective atoms may be used, for example, in quantum noise quenching.
