Three-magnetic fields
arXiv:1112.1356 · doi:10.1103/PhysRevD.85.083508
Abstract
A completely new mechanism to generate the observed amount of large-scale cosmological magnetic fields is introduced in the context of three-form inflation. The amplification of the fields occurs via fourth order dynamics of the vector perturbations and avoids the backreaction problem that plagues most previously introduced mechanisms.
