Non-minimal $α$ -attractor magnetogenesis with potential dependent couplings

Antonino G. Marino, Tommaso Mengoni

We investigate inflationary magnetogenesis driven by a non conformal coupling in the case of large-field $α$ -attractor inspired models. We introduce potential-dependent electromagn…

Inflationary magnetogenesis from non-minimal coupling in large- and small-field potentials

Orlando Luongo, Antonino Giacomo Marino, Tommaso Mengoni

We investigate inflationary magnetogenesis in a scenario where conformal invariance of electromagnetism is broken through a \emph{non-minimal Yukawa-like coupling between the infla…
