Parametric Resonance and Backreaction Effects in Magnetogenesis from Ultralight Dark Matter
Nirmalya Brahma, Robert Brandenberger
We take a more detailed look at the recently proposed magnetogenesis mechanism triggered by ultralight dark matter coupled to electromagnetism. The proposed mechanism made use of a…

Resonant axion and dark photon production in magnetic white dwarfs
Nirmalya Brahma, Ella Iles, Hugo Schérer +1
Using magnetic white dwarfs as a case study, we show that the emission of sub-MeV bosons from stellar plasmas can be substantially modified in the presence of a magnetic field. In…

Photon conversion to axions and dark photons in magnetized plasmas: a finite-temperature field theory approach
Nirmalya Brahma, Katelin Schutz
Some of the most stringent constraints on physics beyond the Standard Model (BSM) arise from considerations of particle emission from astrophysical plasmas. However, many studies a…
