论文摘要
我们研究了与两个机械振荡器的三模腔光学机械系统中非线性相互作用的谐振增强。通过使用Keldysh Green的功能技术，我们发现由于它们的有效耗散较小，因此可以通过两个声音极化子的谐振散射来大大增强对状态腔密度的非线性影响。在较大的失调极限并考虑到可实现的穿着耦合的上限，获得了探测非线性效应的最佳点，这表明这种三模式系统可以表现出显着的非线性特征，对于$ g/κ$的相对较小的值也可以表现出明显的非线性特征。
We investigate the resonant enhancement of nonlinear interactions in a three-mode cavity optomechanical system with two mechanical oscillators. By using the Keldysh Green's function technique we find that nonlinear effects on the cavity density of states can be greatly enhanced by the resonant scattering of two phononic polaritons, due to their small effective dissipation. In the large detuning limit and taking into account an upper bound on the achievable dressed coupling, the optimal point for probing the nonlinear effect is obtained, showing that such three-mode system can exhibit prominent nonlinear features also for relatively small values of $g/κ$.
