用高阶超几何函数精确可解的量子力学势。第一章:第三阶段

Quantum mechanical potentials exactly solvable in terms of higher hypergeometric functions. I: The third-order case

Stephanos Trachanas

摘要:

提出了一个新的六参数势族,其解用超几何函数3F2、2F2和1F2表示。散射数据和这些潜在的束缚态显式计算和特殊性质的离散谱描绘在一个合适的相图。我们的出发点是一个三阶形式的特征值方程的超几何类型(与一个合适的解决方案已知),这是转化为薛定谔方程通过应用降阶技术作为关键的第一步。文章最后讨论了任意高阶本征值方程简化为薛定谔形式的一般前提条件,并对由此产生的势的两个普遍特征进行了说明和讨论。在这个一般方案中,Natanzon势是最简单的特例,这里介绍的是下一个特例,对于由四阶或更高阶方程产生的势也是如此。

英文摘要:

We present a new six-parameter family of potentials whose solutions are expressed in terms of the hypergeometric functions 3F2, 2F2 and 1F2. Both the scattering data and the bound states of these potentials are explicitly computed and the peculiar properties of the discrete spectrum are depicted in a suitable phase diagram. Our starting point is a third-order formal eigenvalue equation of the hypergeometric type (with a suitable solution known) which is transformed to the Schrödinger equation by applying the reduction of order technique as the crucial first step. The general preconditions allowing for the reduction to Schrödinger form of an arbitrary eigenvalue equation of higher order, are discussed at the end of the article, and two universal features of the potentials arising this way are also stated and discussed. In this general scheme the Natanzon potentials are the simplest special case, those presented here the next ones, and so on for potentials arising from equations of fourth or higher order.
