How to suppress exponential growth -- on the parametric resonance of photons in an axion background
Ariel Arza, Thomas Schwetz, Elisa Todarello
Axion--photon interactions can lead to an enhancement of the electromagnetic field by parametric resonance in the presence of a cold axion background, for modes with a frequency cl…

Axion-electrodynamics: a quantum field calculation
Marc Beutter, Andreas Pargner, Thomas Schwetz +1
An axion background field induces tiny oscillating electric and magnetic fields in an external static magnetic field. This signature is used to search for axion dark matter. We use…
