强场QED中的辐射反应

Radiation reaction in strong field QED

Anton Ilderton, Greger Torgrimsson

摘要:

我们从QED导出了强背景场中的辐射反应。我们确定,在一般情况下,图和过程有助于反冲效应的平均动量的散射电子,使用微扰理论的毛茸茸的图片:我们的工作,以最低的非平凡的顺序在电磁耦合α。对于明确的例子中的散射在平面波的背景下,我们比较QED与经典电动力学的限制h-酒吧去为零,发现协议与洛伦兹-亚伯拉罕-狄拉克和朗道-Lifshitz方程,并与拉莫尔的公式。第一个量子修正也被提出。

英文摘要:

We derive radiation reaction from QED in a strong background field. We identify, in general, the diagrams and processes contributing to recoil effects in the average momentum of a scattered electron, using perturbation theory in the Furry picture: we work to lowest nontrivial order in the electromagnetic coupling alpha. For the explicit example of scattering in a plane wave background, we compare QED with classical electrodynamics in the limit h-bar goes to zero, finding agreement with the Lorentz-Abraham-Dirac and Landau-Lifshitz equations, and with Larmor's formula. The first quantum corrections are also presented.
