一维Schroedinger方程的可积性

Integrability of the one dimensional Schroedinger equation

Thierry Combot

摘要:

本文给出了一维Schroedinger方程的可积性定义,它包含了所有已知的可积系统,即谱可以显式计算的系统。为此,我们引入一类刚性函数,建立Liouvillian函数,但包含所有解决方案的刚性微分算子的意义上的卡茨,和一个概念的自然边界条件。然后,我们对有理可积势进行了完整的分类。许多新的可积的情况下发现,其中一些物理上有趣的。

英文摘要:

We present a definition of integrability for the one dimensional Schroedinger equation, which encompasses all known integrable systems, i.e. systems for which the spectrum can be explicitly computed. For this, we introduce the class of rigid functions, built as Liouvillian functions, but containing all solutions of rigid differential operators in the sense of Katz, and a notion of natural boundary conditions. We then make a complete classification of rational integrable potentials. Many new integrable cases are found, some of them physically interesting.
