No cosmological constraints on dark photon dark matter from resonant conversion: Impact of nonlinear plasma dynamics
Anson Hook, Junwu Huang, Mohamad Shalaby
We revisit and invalidate all dark photon dark matter constraints from resonant conversion of dark photons into photons (plasmons) in the early universe. These constraints rely on…

Adiabatic Conversion of ALPs into Dark Photon Dark Matter
Edward Broadberry, Saurav Das, Anson Hook +1
We introduce a mechanism by which a misaligned ALP can be dynamically converted into a dark photon in the presence of a background magnetic field. An abundance of non-relativistic…
