非平方哈密顿量的摄动法及其在多项式振子中的应用

Perturbation method for non-square Hamiltonians and its application to polynomial oscillators

Miloslav Znojil

摘要:

本文对Rayleigh-Schroedinger微扰法作了一个显著的推广,它的(N+q)×(N+1)维哈密顿量(如新出现的,在束缚态的准精确构造期间)在q > 1处是非方阵。本征值的作用由能量/耦合q-小峰发挥。在所有阶中,其扰动通过q维反演来定义。

英文摘要:

A remarkable extension of Rayleigh-Schroedinger perturbation method is found. Its (N+q) x (N+1) - dimensional Hamiltonians (as emerging, e.g., during quasi-exact constructions of bound states) are non-square matrices at q > 1. The role of an eigenvalue is played by an energy/coupling q-plet. In all orders, its perturbations are defined via a q-dimensional inversion.
