Coherent axion electrodynamics in OSIRIS: a counter-propagating axion-photon parametric instability
Miles Radford, Pablo Bilbao, Thomas Grismayer +4
We present a coherent axion-electrodynamics extension of the OSIRIS particle-in-cell code and use it to identify and benchmark a parametric axion-photon instability supported by tw…

An axion framework for Particle-in-Cell codes with Monte-Carlo sampling: emission, absorption, and detailed balance in plasmas
Miles Radford, Ahmed Alsulami, Bertrand Martinez +5
We present an extension of the OSIRIS particle-in-cell (PIC) code that introduces an axion macroparticle species and three axion-production channels commonly used in thermal-plasma…

Probing keV mass QCD axions with the SACLA X-ray free electron laser
Charles Heaton, Jack W. D. Halliday, Taito Osaka +12
Axions are hypothetical particles, proposed to account for the invariance of CP symmetry in quantum chromodynamics. While axions and axion-like-particles are well-motivated by stri…
