DOI: 10.1103/physrevd.100.063523
Abstract: We study magnetogenesis in axion-like inflation driven by a pseudoscalar field $\phi$ coupled axially to the electromagnetic (EM) field $(\beta/M_{p})\phi F_{\mu\nu}\tilde{F}^{\mu\nu}$ with dimensionless coupling constant $\beta$. A set of equations for the inflaton field, scale… read more here.

DOI: 10.1103/physrevd.102.045010
Abstract: We compute the discharging rate of a uniform electric field due to Schwinger pair production in ($1+1$)-dimensional scalar electrodynamics with a compact dimension of radius $R$. Our calculation is performed in real time, using the… read more here.
