摘要

考虑到无质量阿贝尔矢量玻色子场打破保形不变性的随时间动力学和轴向耦合引起的暴胀磁生，我们在本文中表明，令人惊讶的是，大尺度原始磁场功率谱的频谱形状对暴胀后历史，即正压参数(w)和后暴胀时代的规范耦合函数不敏感。2025年由美国物理学会出版

Is inflationary magnetogenesis sensitive to the postinflationary history?

Considering inflationary magnetogenesis induced by time-dependent kinetic and axial couplings of a massless Abelian vector boson field breaking the conformal invariance, we show in this article that, surprisingly, the spectral shape of the large-scale primordial magnetic field power spectrum is insensitive to the postinflationary history, namely, the barotropic parameter (w) and the gauge coupling functions of the postinflationary era.
