论文摘要
两级系统的扩展收集的多体衰变仍然是一个开放的问题。在这里，我们调查了一系列发射器是否耦合到一维浴场是否经历了Dicke的超赞。这是一个过程，通过耗散，完全倒置的系统变得相关，从而导致所有能量以快速光子爆发的形式释放。我们得出了爆发的最小条件，这是发射器数量，波导的手性以及单发射极深度的函数，无论是有序的和无序的合奏。发生多体超级后，之所以发生，因为在整个衰减过程中，触发发射的初始波动会扩大。在一维浴中，这种雪崩般的行为会导致自发的镜像对称性破裂，并在发射到左右的光子数量上发生了很大的射击波动。因此，超级爆发可能是一种吸烟枪，用于产生异国量子统计的相关光子状态。
The many-body decay of extended collections of two-level systems remains an open problem. Here, we investigate whether an array of emitters coupled to a one-dimensional bath undergoes Dicke superradiance. This is a process whereby a completely inverted system becomes correlated via dissipation, leading to the release of all the energy in the form of a rapid photon burst. We derive the minimal conditions for the burst to happen as a function of the number of emitters, the chirality of the waveguide, and the single-emitter optical depth, both for ordered and disordered ensembles. Many-body superradiance occurs because the initial fluctuation that triggers the emission is amplified throughout the decay process. In one-dimensional baths, this avalanchelike behavior leads to a spontaneous mirror symmetry breaking, with large shot-to-shot fluctuations in the number of photons emitted to the left and right. Superradiant bursts may thus be a smoking gun for the generation of correlated photon states of exotic quantum statistics.
