非均匀磁场在真空中产生具有反常磁矩的中性费米子

Creation of neutral fermions with anomalous magnetic moment from vacuum by inhomogeneous magnetic field

S. P. Gavrilov, D. M. Gitman

摘要:

到目前为止,人们还不知道中性粒子在强不均匀磁场中产生(由于它们的磁矩)的一致描述(基于量子场论)。提供这样的描述是本文的一部分。在所开发的方法的框架中,我们表明,在特定的情况下,该问题可以在技术上减少到由非线性标量势给出的电场的带电粒子创建的问题。我们再次分析后一个问题,考虑到现有的方法,并制定第一次从QFT的角度来看,它的解决方案。作为最后的结果,我们计算了中性粒子的产生从真空中的线性增长的磁场。

英文摘要:

Until now a consistent description (based on QFT) of neutral particle creation (due to their magnetic moments) in strong inhomogeneous magnetic fields was unknown. To provide such a description is a part of the present article. In the framework of the developed approach, we demonstrate that in a specific cases, the problem can be technically reduced to the problem of charge particle creation by an electric field given by a nonlinear scalar potential. We analyze once again the latter problem, taking into account existing approaches and formulating for the first time its solution from the view point of QFT. As a final result, we calculate neutral particle creation form the vacuum by a linearly growing magnetic field.
