论文摘要
从理论上讲，我们与两个原子的同时衰变一起研究了原子集合的集体辐射特征。我们表明，两种原子的衰减可以显着抑制原子的稳态集体辐射，从而扩大了亚降低区域。在稳态次级统治状态中，该系统处于纠缠状态，并且在原子的激发状态和基态下，系统的平均种群几乎相等。两种原子衰减的过程可以通过在迪克梯子上的系统状态的种群分布来证明。此外，我们显示了来自原子集合的发射光的相关属性，在两个原子衰减的存在下，相关函数被重写。我们发现，在两种原子衰减的情况下，稳态发射的光子仅显示束。这项工作扩大了集体辐射的领域，并具有潜在的量子信息处理应用程序。
We investigate theoretically the collective radiance characteristics of an atomic ensemble with the simultaneous decay of two atoms. We show that the two-atom decay can significantly suppress the steady-state collective radiance of the atoms, expanding the region of subradiance. In the steady-state subradiance regime, the system is in an entangled state, and the mean populations of the system in the excited state and ground state of the atoms are almost equal. The processes of the two-atom decay can be demonstrated by the population distribution of the system state on the Dicke ladder. Moreover, we show the correlation property of the emitted light from the atomic ensemble, where the correlation function is rewritten in the presence of the two-atom decay. We find that the emitted photons of steady state only show bunching in the case of two-atom decay. This work broadens the realm of collective radiance, with potential applications for quantum information processing.
