论文摘要
远程Rydberg相互作用结合电磁诱导的透明度（EIT），产生强烈相互作用的光子，在这种光子中，相互作用的强度，符号和形式可广泛可调且可控制。这种控制可以应用于相干和耗散性相互作用，这为产生新型的少数光子状态提供了潜力。最近，已经显示，Rydberg-eit是一个罕见的系统，其中三体相互作用比两体相互作用都具有强大或强大。在这项工作中，我们研究了Rydberg-eit的三体散射损失，这是一个单一和两光子失误的范围。我们基于费米的黄金法则对完整三体波函数和分析估计值的数值模拟强烈表明，即传出光子相关性中观察到的特征是由三体损失的谐振增强引起的。
Long-range Rydberg interactions, in combination with electromagnetically induced transparency (EIT), give rise to strongly interacting photons where the strength, sign, and form of the interactions are widely tunable and controllable. Such control can be applied to both coherent and dissipative interactions, which provides the potential to generate novel few-photon states. Recently it has been shown that Rydberg-EIT is a rare system in which three-body interactions can be as strong or stronger than two-body interactions. In this work, we study a three-body scattering loss for Rydberg-EIT in a wide regime of single and two-photon detunings. Our numerical simulations of the full three-body wavefunction and analytical estimates based on Fermi's Golden Rule strongly suggest that the observed features in the outgoing photonic correlations are caused by the resonant enhancement of the three-body losses.
