Compton scattering in particle-in-cell codes

Abstract

We present a Monte Carlo collisional scheme that models single Compton scattering between leptons and photons in particle-in-cell codes. The numerical implementation of Compton scattering can deal with macro-particles of different weights and conserves momentum and energy in each collision. Our scheme is validated through two benchmarks for which exact analytical solutions exist: the inverse Compton spectra produced by an electron scattering with an isotropic photon gas and the photon-electron gas equilibrium described by the Kompaneets equation. It opens new opportunities for numerical investigation of plasma phenomena where a significant population of high energy photons is present in the system.
