摘要

辐射反应会严重影响超相对论粒子在强电磁场中的运动。在此，我们研究了经典和量子环境下辐射反应动力学建模的粒子胞内(PIC)方法。我们在两个开放源代码的PIC代码Smilei和EPOCH中测试了高能粒子在强电磁场中运动的光子发射方法。我们对代码进行基准测试并讨论其差异。

Radiation generation during laser and particle beam interactions in particle-in-cell codes

Radiation reaction can severely affect the motion of ultra-relativistic particles in intense electromagnetic fields. Here, we study particle-in-cell (PIC) methods of kinetic modeling of radiation reaction in classical and quantum regimes. We test the methods of photon emission from highly energetic particles moving in strong electromagnetic field in two open-source PIC codes Smilei and EPOCH. We benchmark the codes and discuss the differences.
