论文摘要

我们展示了如何在(脉冲)平面波背景字段中的非线性三叉戟过程中考虑量子辐射反应和自旋跃迁,并考虑到量子辐射反应和自旋跃迁。因此,结果是背景场强,$ ee $的非平凡函数,以及与量化光子场的耦合,$α= e^2/4π$。有效的扩展参数$ t $为$α$ times $ ee/mΩ\ gg1 $,这使得更高的订单很重要。我们表明,他们可以在$ t <1 $上更改旋转依赖零件的迹象,这将是可以在实验上访问的。

We show how to resum the Furry-picture $α$ expansion in order to take quantum radiation reaction and spin transition into account in the nonlinear trident process in (pulsed) plane-wave background fields. The results are therefore nontrivial functions of both the background field strength, $eE$, and the coupling to the quantized photon field, $α=e^2/4π$. The effective expansion parameter, $T$, is $α$ times $eE/mω\gg1$, which makes higher orders important. We show that they can change the sign of the spin dependent part already at $T<1$, which will be experimentally accessible.
