One-loop electromagnetic correlators of SQED in power-law inflation

We examine scalar quantum electrodynamics in power-law inflation, and compute the one-loop correction to electric and magnetic field correlators at superhorizon separations. The effect at one-loop descends from the coupling of the vector to the charged scalar current which is greatly enhanced due to...
