YUNIC: A Multi-Dimensional Particle-In-Cell Code for Laser-Plasma Interaction

Abstract

For simulating laser-plasma interactions, we developed a parallel, multi-dimensional, fully relativistically particle-in-cell (PIC) code, named YUNIC. The core algorithm is introduced, including field solver, particle pusher, field interpolation, and current interpolation. In addition to the classical electromagnetic interaction in plasmas, nonlinear Compton scattering and nonlinear Breit-Wheeler pair production are also implemented based on Monte-Carlo methods to study quantum electrodynamics (QED) processes. We benchmark YUNIC against theories and other PIC codes through several typical cases. YUNIC can be applied in varieties of physical scenes, from relativistic laser-plasma interactions to astrophysical plasmas and strong-field QED physics.
