平面波中量子辐射反应的恢复

Resummation of quantum radiation reaction in plane waves

Greger Torgrimsson

摘要:

本文提出了一种新的方法来获得高强度激光中电子的动量期望值,包括多光子发射和环。我们发现一个递归公式,使我们能够获得$\mathcal{O}(α^n)$长期从$\mathcal{O}(α^{n-1})$,这也可以表示为一个积分微分方程。在经典极限下,我们得到了Landau-Lifshitz方程的所有阶的解。我们展示了如何自旋相关的量子辐射反应,可以得到通过图解的能量展开以及$α$展开。

英文摘要:

We propose a new approach to obtain the momentum expectation value of an electron in a high-intensity laser, including multiple photon emissions and loops. We find a recursive formula that allows us to obtain the $\mathcal{O}(α^n)$ term from $\mathcal{O}(α^{n-1})$, which can also be expressed as an integro-differential equation. In the classical limit we obtain the solution to the Landau-Lifshitz equation to all orders. We show how spin-dependent quantum radiation reaction can be obtained by resumming both the energy expansion as well as the $α$ expansion.
