论文摘要
我们得出了一个简单的独立于模型的上限,这些上限是在通货膨胀和通货膨胀后磁化中获得的磁场强度,考虑到弱耦合,反反应和schwinger效应所施加的约束。对于宇宙学上有趣的空间尺度而言,这种结合非常低。如果人们假设某些未知机制抑制早期宇宙中的Schwinger效应,则获得了较高的上限。顺便说一句,我们纠正了以前对此案的估计。
We derive a simple model-independent upper bound on the strength of magnetic fields obtained in inflationary and post-inflationary magnetogenesis taking into account the constraints imposed by the condition of weak coupling, back-reaction and Schwinger effect. This bound turns out to be rather low for cosmologically interesting spatial scales. Somewhat higher upper bound is obtained if one assumes that some unknown mechanism suppresses the Schwinger effect in the early universe. Incidentally, we correct our previous estimates for this case.
