Large-scale magnetic fields from inflation due to Chern-Simons-like effective interaction

K. Bamba, C. Q. Geng, S. H. Ho

We discuss the generation of large-scale magnetic fields due to the breaking of the conformal invariance in the electromagnetic field through the $C P T$ -even dimension-six Chern-Sim…

Generic estimates for magnetic fields generated during inflation including Dirac-Born-Infeld theories

Kazuharu Bamba, Nobuyoshi Ohta, Shinji Tsujikawa

We estimate the strength of large-scale magnetic fields produced during inflation in the framework of Dirac-Born-Infeld (DBI) theories. This analysis is sufficiently general in the…

Inflation and late-time cosmic acceleration in non-minimal Maxwell- $F (R)$ gravity and the generation of large-scale magnetic fields

Kazuharu Bamba, Sergei D. Odintsov

We study inflation and late-time acceleration in the expansion of the universe in non-minimal electromagnetism, in which the electromagnetic field couples to the scalar curvature f…
