论文摘要
我们提出了一种诊断多模式开放系统中强耦合的新方法。我们的方法提出了针对此类系统采用的特殊点（EP）分析的非平地扩展；具体而言，我们展示了特征向量如何不仅可以重现EPS预测的所有功能，还可以识别在强耦合方案的不同区域中杂交的物理模式。作为演示，我们将此方法应用于三模式光力学系统中的杂交物理，并确定在存在储层相关性的情况下机械振荡器有效的侧带冷却的参数状态。
We present a new method to diagnose strong coupling in multi-mode open systems. Our method presents a non-trivial extension of exceptional point (EP) analysis employed for such systems; specifically, we show how eigenvectors can not only reproduce all the features predicted by EPs but are also able to identify the physical modes that hybridize in different regions of the strong coupling regime. As a demonstration, we apply this method to study hybridization physics in a three-mode optomechanical system and determine the parameter regime for efficient sideband cooling of the mechanical oscillator in the presence of reservoir correlations.
