abstract = {Building on recently constructed inflationary vector dark matter production
mechanisms as well as studies of magnetogenesis, we show that an inflationary dark Schwinger
mechanism can generate the observed dark matter relic abundance for ‘dark electron’ masses
as light as ∼ 0.1 eV and as heavy as 1012 GeV. The dark matter can interact very weakly
via the exchange of light dark photons with a power spectrum which is peaked at very small
scales, thus evading isocurvature constraints. This mechanism is viable even when (purely)
gravitational particle production is negligible. Thus dark matter can be produced solely via
the Schwinger effect during inflation including for light masses.},
