High-order harmonic generation in an electron-positron-ion plasma
W. L. Zhang, T. Grismayer, K. M. Schoeffler +2
The laser interaction with an electron-positron-ion mixed plasma is studied, from the perspective of the associated high-order harmonic generation. For an idealized mixed plasma wh…
Kinetic model of large-amplitude oscillations in neutron star pair cascades
Fábio Cruz, Thomas Grismayer, Luis O. Silva
Electron-positron pair cascades developed in the extreme electromagnetic fields of neutron star polar caps are considered a key source of magnetospheric plasma in these objects. We…
Scaling laws for direct laser acceleration in a radiation-reaction dominated regime
M. Jirka, M. Vranic, T. Grismayer +1
We study electron acceleration within a sub-critical plasma channel irradiated by an ultra-intense laser pulse ( or ). In this regime, radiation…
Compton scattering in particle-in-cell codes
F. Del Gaudio, T. Grismayer, R. A. Fonseca +1
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 sca…
Plasma wakes driven by photon bursts via Compton scattering
Fabrizio Del Gaudio, Ricardo Fonseca, Luis O. Silva +1
Photon bursts with a wavelength smaller than the plasma inter-particle distance can drive plasma wakes via Compton scattering. We investigate this fundamental process analytically…
