非厄米特算子的例外点

Exceptional Points of Non-hermitian Operators

W. D. Heiss

摘要:

例外点与非厄米特运营商,即运营商是非厄米特的实参数值,进行了研究。得出了异常点处本征函数的具体特征。在实参数的域中,例外点是特征值从实值切换到复值的点。这些和其他结果的例子是一个经典的问题,导致异常点的非厄米矩阵。

英文摘要:

Exceptional points associated with non-hermitian operators, i.e. operators being non-hermitian for real parameter values, are investigated. The specific characteristics of the eigenfunctions at the exceptional point are worked out. Within the domain of real parameters the exceptional points are the points where eigenvalues switch from real to complex values. These and other results are exemplified by a classical problem leading to exceptional points of a non-hermitian matrix.
