摘要
利用世界线形式体系，我们计算了在时调电场和空调磁场下费米子的有效作用量。已知前者导致增强的施温格机制，而我们发现后者也能导致增强的粒子产生，甚至引起真空重组从而在平衡态获得更大的动力学质量，这在空间上辅助了磁催化。

备注
This is an erratum applied version to PRL117, 081603 (2016). We found a sign mistake and wrote an erratum with a conclusion that the central results are not changed once spatially decreasing magnetic fields are replaced with increasing ones. The Gaussian approximation leading to a wrong answer has also been improved to a systematic perturbative evaluation
