在强烈背景下传播

Propagation in an intense background

Martin Lavelle, David McMullan, Merfat Raddadi

摘要:

本文研究了强激光背景中带电粒子的正则量子化,并计算了相应的两点函数。它示出了如何因果传播可以提取。我们提供了一个解释,这个传播的简并量子过程。的传播子的光谱特性的推导,我们展示了如何多极结构出现作为一个微扰功能。我们还计算了相关的多重波函数重整化的所有订单微扰论。我们的计算是圆形和线性偏振平面波激光背景。

英文摘要:

The canonical quantisation of a charged particle in an intense laser background is developed and the associated two-point function calculated. It is shown how the causal propagator can be extracted. We provide an interpretation of this propagator in terms of degenerate quantum processes. The spectral properties of the propagator are derived and we show how multi-pole structures emerge as a perturbative feature. We also calculate the associated multiple wave-function renormalisations to all orders in perturbation theory. Our calculations are for both circular and linearly polarised plane wave laser backgrounds.
