Suppressed Magnetogenesis from Ultralight Dark Matter due to Finite Conductivity

Ramkishor Sharma, Samarth Majumdar, Divya Sachdeva

Recently, a mechanism for generating astrophysically relevant magnetic fields via ultralight pseudoscalar dark matter, through the coupling term $g_{ϕγ} ϕF_{μν}\tilde{F}^{μν…
