Description
In this talk I will review aspects of the inflationary Schwinger effect and its implications for dark matter. As part of this I will review the calculation of the Schwinger current in de Sitter space and show how peculiar IR divergences found in previous calculations can be cured. I will then review how the dark matter relic abundance can be generated through the inflationary Schwinger effect leading to a combination of vector and dark charged fermion or scalar dark matter today and discuss potential phenomenological implications.
