摘要: We consider the possibility of inflationary magnetogenesis due to dynamical couplings of the elec-tromagnetic 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.
