Influence of backreaction of electric fields and Schwinger effect on inflationary magnetogenesis

O. O. Sobol, E. V. Gorbar, M. Kamarpour +1

We study the generation of electromagnetic fields during inflation when the conformal invariance of Maxwell's action is broken by the kinetic coupling $f^2(\varphi )F_{\mu \nu }{F}^{\mu \nu }$ of the…
