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…
Generative Diffusion Surrogates with Analytical Variance Schedule
Patrick Reichherzer, Gianluca Gregori, David N. Hosking +1
Stochastic transport describes physical systems in which an initially structured distribution spreads under unresolved forcing, scattering, or heterogeneous media. Useful surrogate…
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…
Suppression of pair beam instabilities in a laboratory analogue of blazar pair cascades
Charles D. Arrowsmith, Francesco Miniati, Pablo J. Bilbao +28
The generation of dense electron-positron pair beams in the laboratory can enable direct tests of theoretical models of -ray bursts and active galactic nuclei. We have successfu…
Bounds on heavy axions with an X-ray free electron laser
Jack W. D. Halliday, Giacomo Marocco, Konstantin A. Beyer +18
We present new exclusion bounds obtained at the European X-ray Free Electron Laser facility (EuXFEL) on axion-like particles (ALPs) in the mass range 10^{-3} eV < m_a < 10^4 eV. Ou…
Axion driven cosmic magneto-genesis during the QCD crossover
Francesco Miniati, Gianluca Gregori, Brian Reville +1
We propose a mechanism for the generation of a magnetic field in the early universe during the QCD crossover assuming that dark matter is made of axions. Thermoelectric fields aris…
