论文摘要
我们探讨了量身定制的轻度杂种状态的非线性响应，在新的方案中，型号由相干驾驶场引起的狂犬病频率和腔场设置的真空狂犬病频率都与光的载体频率相当。在以前未开发的超局势耦合的强场限制中，不同极性状态之间的多波泵探针和多波混合非线性违反了正常模式近似，而Ultrastrong耦合仍然完好无损，如我们的均值场模型所证实。我们期望杂交基本激发的定制非线性促进具有虚拟光子的非经典光源，量子相变或腔化学。
We explore the nonlinear response of tailor-cut light-matter hybrid states in a novel regime, where both the Rabi frequency induced by a coherent driving field and the vacuum Rabi frequency set by a cavity field are comparable to the carrier frequency of light. In this previously unexplored strong-field limit of ultrastrong coupling, subcycle pump-probe and multi-wave mixing nonlinearities between different polariton states violate the normal-mode approximation while ultrastrong coupling remains intact, as confirmed by our mean-field model. We expect such custom-cut nonlinearities of hybridized elementary excitations to facilitate non-classical light sources, quantum phase transitions, or cavity chemistry with virtual photons.
