Model of inflationary magnetogenesis
arXiv:1512.05050 · doi:10.1103/PhysRevD.93.043541
Abstract
We consider the possibility of inflationary magnetogenesis due to dynamical couplings of the electromagnetic fields to gravity. We find that large primordial magnetic fields can be generated during inflation without the strong coupling problem, backreaction problem, or curvature perturbation problem, which seed large-scale magnetic fields with observationally interesting strengths.
