狄拉克空穴理论与量子场论的一些区别

Some differences between Dirac's hole theory and quantum field theory

Dan Solomon

摘要:

Dirac空穴理论(HT)和量子场论(QFT)通常被认为是相互等价的。然而,最近几位研究人员表明,情况不一定如此。当计算真空能量的变化时,对于与时间无关的微扰,HT和QFT得到不同的结果。在本文中,我们扩展这一讨论,包括一个依赖于时间的扰动的狄拉克方程的精确解是已知的。它将表明,对于这种情况下,HT和QFT也产生不同的结果。此外,还将讨论QFT中的异常问题。

英文摘要:

Diracs hole theory (HT) and quantum field theory (QFT) are generally considered to be equivalent to each other. However, it has been recently shown by several researchers that this is not necessarily the case. When the change in the vacuum energy was calculated for a time independent perturbation HT and QFT yielded different results. In this paper we extend this discussion to include a time dependent perturbation for which the exact solution to the Dirac equation is known. It will be shown that for this case, also, HT and QFT yield different results. In addition, there will be some discussion of the problem of anomalies in QFT.
