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…

Neural network sampling of Bethe-Heitler process in particle-in-cell codes
Ãscar Amaro, Chiara Badiali, Bertrand Martinez
This study uses neural networks to improve Monte Carlo (MC) implementations of the Bethe-Heitler process in Particle-In-Cell (PIC) codes. We provide a neural network that is as acc…
