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…

Entanglement degradation in regular and singular spacetimes
Orlando Luongo, Stefano Mancini, Sebastiano Tomasi
We study entanglement degradation near the horizons of regular, Reissner-Nordström, and Schwarzschild-de Sitter black holes, considering the Bardeen, Hayward, and generalized Hayw…
