论文摘要
我们研究了通过强耦合的两级发射器发出的光中的两色光子相关性。光谱滤波使我们能够操纵收集的光统计数据，我们表明，偶极 - 偶极相互作用引起的共振产生了特定的相关性，在这种相关时间对称性的情况下，相关性被损坏。基于集体着装状态，我们的研究涵盖了真实过程的情况，其中光子与彼此之间的特定共振和经典相关性以及虚拟过程相关联，其中一对光子与非经典相关性发出。
We investigate two-color photon correlations in the light emitted by strongly coupled two-level emitters. Spectral filtering allows us to manipulate the collected light statistics and we show that the resonances induced by dipole-dipole interactions give rise to specific correlations, where the time-symmetry of the correlations is broken. Based on the collective dressed states, our study encompasses both the case of real processes, where the photons are associated with specific resonances and classical correlations between each other, and virtual processes, where pairs of photons are emitted with non-classical correlations.
