研究超高强度激光与等离子体、激光与光束相互作用中的自旋和极化效应是近年来强场科学中的一个新兴课题。在本文中，我们推导出一个相对论动力学描述的自旋极化等离子体，量子电动力学效应考虑通过玻尔兹曼型碰撞算符下的局域常数场近似。反常旋进的出现来源于强背景场中的单圈自能贡献。我们特别感兴趣的是辐射反应效应和辐射粒子的自旋极化之间的相互作用。为此，我们从自旋极化动力学方程的矩出发，导出了自旋极化量子辐射反应方程。通过与经典理论的比较，我们识别并讨论了自旋相关的辐射反应项和辐射对自旋动力学的贡献。
The investigation of spin and polarization effects in ultra-high intensity laser–plasma and laser–beam interactions has become an emergent topic in high-field science recently. In this paper, we derive a relativistic kinetic description of spin-polarized plasmas, where quantum-electrodynamics effects are taken into account via Boltzmann-type collision operators under the local constant field approximation. The emergence of anomalous precession is derived from one-loop self-energy contributions in a strong background field. We are interested, in particular, in the interplay between radiation reaction effects and the spin polarization of the radiating particles. For this, we derive equations for spin-polarized quantum radiation reaction from moments of the spin-polarized kinetic equations. By comparing with the classical theory, we identify and discuss the spin-dependent radiation reaction terms and radiative contributions to spin dynamics.
