Light Dark Photon Dark Matter from Inflation
read the original abstract
We discuss the possibility of producing a light dark photon dark matter through a coupling between the dark photon field and the inflaton. The dark photon with a large wavelength is efficiently produced due to the inflaton motion during inflation and becomes non-relativistic before the time of matter-radiation equality. We compute the amount of production analytically. The correct relic abundance is realized with a dark photon mass extending down to $10^{-21} \, \rm eV$.

Classical constant electric fields and the Schwinger effect in de Sitter
Constant electric fields in de Sitter require a tachyonic photon mass ~H, yielding finite positive Schwinger currents for massless fermions and scalars after on-shell renormalization.

Illuminating sequential freeze-in dark matter with dark photon signal at the CERN SHiP experiment
Sequential freeze-in dark matter with a dark photon mediator of mass 0.01-10 GeV fixes the dark charge at 1.3e-12 and restricts mixing to 10^{-11} to ~10^{-8}, with SHiP excluding most of this range except near 10^{-11}.
