Post-inflationary axion isocurvature perturbations facing CMB and large-scale structure
Martin Feix, Steffen Hagstotz, Andreas Pargner +3
Dark matter comprised of axion-like particles (ALPs) generated by the realignment mechanism in the post-inflationary scenario leads to primordial isocurvature fluctuations. The pow…
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…
Axion minicluster power spectrum and mass function
Jonas Enander, Andreas Pargner, Thomas Schwetz
When Peccei-Quinn (PQ) symmetry breaking happens after inflation, the axion field takes random values in causally disconnected regions. This leads to fluctuations of order one in t…
