将薛定谔方程转化为Shabat-Zakharov系统

Reformulating the Schrodinger equation as a Shabat-Zakharov system

Petarpa Boonserm, Matt Visser

摘要:

我们将二阶薛定谔方程转化为一组两个耦合的一阶微分方程,即所谓的“Shabat-Zakharov系统”(有时也称为“Zakharov-Shabat”系统)。有相当大的灵活性,在这种方法中,我们强调的效用,引入一个“辅助条件”或“规范条件”,用于削减自由度。使用这种形式主义,我们得到明确的(但正式的)薛定谔方程的一般解决方案。一般的解决方案取决于三个任意选择的功能,和一个路径有序的指数矩阵。如果把路径排序看作是一个“初等”过程,那么这就代表了二阶线性常微分方程的完全求积(尽管是形式上的)。

英文摘要:

We reformulate the second-order Schrodinger equation as a set of two coupled first order differential equations, a so-called "Shabat-Zakharov system", (sometimes called a "Zakharov-Shabat" system). There is considerable flexibility in this approach, and we emphasise the utility of introducing an "auxiliary condition" or "gauge condition" that is used to cut down the degrees of freedom. Using this formalism, we derive the explicit (but formal) general solution to the Schrodinger equation. The general solution depends on three arbitrarily chosen functions, and a path-ordered exponential matrix. If one considers path ordering to be an "elementary" process, then this represents complete quadrature, albeit formal, of the second-order linear ODE.
