We consider a simple setup with a dark sector containing dark electrons charged under an Abelian 𝑈⁢(1)𝐷 gauge symmetry. We show that, if the massless dark photon associated to the 𝑈⁢(1)𝐷 is produced during inflation in such a way as to form a classical dark electric field, then dark electron-pos ...

We study constant classical electric fields and the Schwinger effect in de Sitter space, with potential implications for magnetogenesis and inflationary dark matter production. Treating the photon as a dynamical field, we show that sustaining a constant electric field in de Sitter requires a tachyon ...

We study classical background electric fields and the Schwinger effect in de Sitter space. We show that a constant electric field in de Sitter requires the photon to have a tachyonic mass proportional to the Hubble scale. This has physical implications for the induced Schwinger current that affect i ...
