D. Seipt, B. King

摘要:

本文导出并讨论了非线性康普顿散射和非线性Breit-Wheeler对产生的完全依赖于自旋和光子极化的几率率。局部恒定场近似,这是必不可少的应用程序中的等离子体QED模拟代码,严格推导出强场QED矩阵元素的Furry图片的一般平面波背景场。我们讨论了这两个过程的光谱中重要的偏振相关效应。小和大值的$χ$的渐近极限推导和它们的自旋/极化依赖性进行了讨论。

英文摘要:

In this paper we derive and discuss the completely spin- and photon-polarisation dependent probability rates for nonlinear Compton scattering and nonlinear Breit-Wheeler pair production. The locally constant field approximation, which is essential for applications in plasma-QED simulation codes, is rigorously derived from the strong-field QED matrix elements in the Furry picture for a general plane-wave background field. We discuss important polarisation correlation effects in the spectra of both processes. Asymptotic limits for both small and large values of $χ$ are derived and their spin/polarisation dependence is discussed.
