求解薛定谔方程低激发态的一种新方法

A New Approach to Solve the Low-lying States of the Schroedinger Equation

T. D. Lee

摘要:

我们回顾了一个新的迭代程序来解决低的薛定谔方程,与理查德弗里德伯格合作完成的状态。对于基态能量,$n^{th}$阶迭代能量是有界的有限的限制,独立于$n$,从而避免了通常的微扰级数展开所面临的一些固有的困难。对于一个相当大的一类问题,这个新的程序可以被证明是收敛的迭代解。这些收敛的解决方案,包括长期存在的困难问题的四次潜力,无论是对称或不对称的最小值。

英文摘要:

We review a new iterative procedure to solve the low-lying states of the Schroedinger equation, done in collaboration with Richard Friedberg. For the groundstate energy, the $n^{th}$ order iterative energy is bounded by a finite limit, independent of $n$; thereby it avoids some of the inherent difficulties faced by the usual perturbative series expansions. For a fairly large class of problems, this new procedure can be proved to give convergent iterative solutions. These convergent solutions include the long standing difficult problem of a quartic potential with either symmetric or asymmetric minima.
