We study in detail a recently proposed mechanism for producing non-thermal dark photon dark matter at the end of inflation in the mass range μ eV≲ m ≲ 10 TeV. A tachyonic instability induced by a rolling inflaton leads to the coherent production of dark (abelian) gauge bosons with a peak in the power spectrum corresponding to the Hubble scale at the end of inflation. As the Universe expands after inflation the dark photons redshift and, at some point in their cosmic evolution, they obtain aarXiv:2103.12145v1 fatcat:tc5foqbj2bgt7llwt2vjbo7a5a
