精确和准精确可解的“离散”量子力学的统一理论:I.形式主义

Unified theory of exactly and quasi-exactly solvable `Discrete' quantum mechanics: I. Formalism

Satoru Odake, Ryu Sasaki

摘要:

在一维离散量子力学中,薛定谔方程是一个差分方程,我们给出了一个构造精确和准精确可解哈密顿量的简单方法。它再现了所有已知的,其特征函数组成的Askey计划的超几何正交多项式的连续或离散变量。该食谱还预测了几个新的。一个重要的作用是由正弦坐标,它产生的封闭关系和Askey-Wilson代数与哈密顿。阐明了闭包关系与Askey-Wilson代数之间的关系。

英文摘要:

We present a simple recipe to construct exactly and quasi-exactly solvable Hamiltonians in one-dimensional `discrete' quantum mechanics, in which the Schrödinger equation is a difference equation. It reproduces all the known ones whose eigenfunctions consist of the Askey scheme of hypergeometric orthogonal polynomials of a continuous or a discrete variable. The recipe also predicts several new ones. An essential role is played by the sinusoidal coordinate, which generates the closure relation and the Askey-Wilson algebra together with the Hamiltonian. The relationship between the closure relation and the Askey-Wilson algebra is clarified.
