波函数的相位与能级排斥
Phases of Wave Functions and Level Repulsion
摘要：
避免水平交叉点与例外点，这是奇异的频谱和本征函数，当它们被认为是一个耦合参数的函数。结果表明，如果例外点被包围在复平面内，{ \it one}态的波函数变号，而另一态的波函数不变。一个实验装置，建议可以观察到这种奇特的相变。
英文摘要：
Avoided level crossings are associated with exceptional points which are the singularities of the spectrum and eigenfunctions, when they are considered as functions of a coupling parameter. It is shown that the wave function of {\it one} state changes sign but not the other, if the exceptional point is encircled in the complex plane. An experimental setup is suggested where this peculiar phase change could be observed.
