评论:“使用多项式解发展微扰理论”J. Math. Phys. 60,012103(2019)

Comment on: "Development of the perturbation theory using polynomial solutions" J. Math. Phys. 60, 012103 (2019)

摘要:

这篇评论的目的是以更清晰的方式介绍Maiz J. Math. Phys. 60,012103(2019)提出的微扰方法。我们的直接程序的结果同意与作者所获得的,除了一种情况下,我们得到的确切结果,而他得到了一个近似的。除此之外,我们还表明,对于足够深的双势阱,微扰方法大大恶化。

英文摘要:

The purpose of this comment is to present the perturbation approach proposed by Maiz J. Math. Phys. 60, 012103 (2019) in a clearer way. The results of our straightforward procedure agree with those obtained by that author except for one case in which we obtain the exact result while he obtained an approximate one. In addition to it, we show that for sufficiently deep double-well potentials the perturbation approach deteriorates considerably.
