Implementation of QED effects in the PIC framework PSC — Constantin Klier, Hartmut Ruhl, Ben King, and •Fabian Deutschmann — Ludwig-Maximilians Universität München, 80539, Germany
The current and next generation (ELI) of laser facilities aim to generate peak intensities in the order of 1025 W/cm2 and higher, entering a regime where the quantum effects of radiation and pair production can no longer be neglected. It is therefore neccessary to incorporate these effects into simulations of the laser-plasma and seeded laser-vacuum interaction under such conditions.
Our group has created a numerical module for the Particle-In-Cell (PIC) framework PSC which is capable of modelling the dynamics of radiation friction, Compton scattering, and e+ e− pair production. In the talk the theoretical foundations and present capabilities of our code will be presented and the numerical challenges will be discussed. In particular, an outline of our solution for an efficient, adaptive Monte-Carlo event-generator for the differential cross-sections needed in the code will be given.
