论文摘要
开放量子和波系统在参数空间的特殊点上表现出异国情调的脱落，在包括光学和光子学在内的各个物理领域引起了相当大的关注。原因之一是这种变性对外部扰动和激发的强烈反应。我们介绍了两个特殊点的特征，这些特征是根据能量特征值和特征态，强度和动力学来量化响应的两个特征。该概念已被验证用于几个与物理相关的例子。这项工作为特殊点的物理学提供了新的观点。
Open quantum and wave systems exhibit exotic degeneracies at exceptional points in parameter space that have attracted considerable attention in various fields of physics, including optics and photonics. One reason is the strong response of open systems at such degeneracies to external perturbations and excitations. We introduce two characteristics of exceptional points that quantify the response in terms of energy eigenvalues and eigenstates, intensity, and dynamics. The concept is verified for several physically relevant examples. This work provides a new perspective on the physics of exceptional points.
