摘要

本文给出了Foldy-Wouthuysen变换的一种新的推广，并给出了利用Ramakrishnan的u矩阵方法获得Foldy-Wouthuysen变换的显式形式及其推广的一种简单而优雅的方法。我们还展示了如何使用这种方法来获得将狄拉克方程连接到文献中最近讨论的狄拉克方程的非协变形式的变换。

A class of transformations on the Dirac Hamiltonian

We give a new generalization of the Foldy-Wouthuysen transformation and show a simple and elegant method of obtaining explicit forms of the Foldy-Wouthuysen transformation and its generalizations by using the U-matrix method of Ramakrishnan. We also show how this method can be used to obtain the transformation which connects the Dirac equation to the non-covariant form of the Dirac equation recently discussed in the literature.
