Abstract
We establish a general framework to explore parametric statistics of individual energy levels in disordered and chaotic quantum systems of unitary symmetry. The method is applied to the calculation of the universal intralevel parametric velocity correlation function and the distribution of level shifts under the influence of an arbitrary external perturbation.
摘要
我们建立了一个通用框架，以探索具有幺正对称性的无序和混沌量子系统中单个能级的参数统计。该方法应用于计算通用的能级内参数速度相关函数以及在任意外部扰动影响下能级移动的分布。
