论文摘要
我们表明，来自平面阵列和原子链的散射光子的两次二阶相关性显示出非经典特征，这些特征可以通过规范单原子$ G_2（τ）$ resonance荧光结果来描述。对于超级另一个，单原子线宽被基础集体低强度本本特征模的线宽所取代。强光诱导的偶极 - 偶极相互作用会导致相关反应，抑制关节光子检测事件以及偶极封闭，抑制了集体原子状态的多种激发。对于有针对性的次级模式，即使与单个原子相比，发射光的非经典性质也可以显着增强。
We show that two-time, second-order correlations of scattered photons from planar arrays and chains of atoms display nonclassical features that can be described by a superatom picture of the canonical single-atom $g_2(τ)$ resonance fluorescence result. For the superatom, the single-atom linewidth is replaced by the linewidth of the underlying collective low light-intensity eigenmode. Strong light-induced dipole-dipole interactions lead to a correlated response, suppressed joint photon detection events, and dipole blockade that inhibits multiple excitations of the collective atomic state. For targeted subradiant modes, nonclassical nature of emitted light can be dramatically enhanced even compared with that of a single atom.
