摘要

强场量子电动力学(SF-QED)在超强激光与物质相互作用中起着至关重要的作用，需要复杂的技术来理解包括自旋角动量在内的新自由度的相关物理。为了研究SF-QED过程的影响，我们在粒子池(PIC)代码中引入了自旋/偏振分辨非线性康普顿散射、非线性bret - wheeler和真空双折射过程。在本文中，我们提供了这些SF-QED模块的实现细节，并分享了与现有单粒子代码完全一致的已知结果。通过将正常的PIC模拟与自旋/偏振分辨的SF-QED过程相结合，我们创建了一个新的理论平台，用于研究当前运行或计划中的千兆瓦或多千兆瓦激光设备中的强场物理。

Simulations of spin/polarization-resolved laser–plasma interactions in the nonlinear QED regime

Strong-field quantum electrodynamics (SF-QED) plays a crucial role in ultraintense laser–matter interactions and demands sophisticated techniques to understand the related physics with new degrees of freedom, including spin angular momentum. To investigate the impact of SF-QED processes, we have introduced spin/polarization-resolved nonlinear Compton scattering, nonlinear Breit–Wheeler, and vacuum birefringence processes into our particle-in-cell (PIC) code. In this article, we provide details of the implementation of these SF-QED modules and share known results that demonstrate exact agreement with existing single-particle codes. By coupling normal PIC simulations with spin/polarization-resolved SF-QED processes, we create a new theoretical platform to study strong-field physics in currently running or planned petawatt or multi-petawatt laser facilities.
