真空双折射中的椭圆效应

Ellipticity induced in vacuum birefringence

Greger Torgrimsson

摘要:

我们考虑在基于激光的低能量实验中的光子-光子散射信号。特别是,我们考虑了强背景场在探测光束上诱导的椭圆率,并将其与最近的光子偏振翻转幅度的世界线表达式进行比较。当探头和背景为平面波时,椭圆率等于翻转幅度。在这里,我们研究更多的物理场的椭圆度振幅关系。

英文摘要:

We consider signals of photon-photon scattering in laser-based, low energy experiments. In particular, we consider the ellipticity induced on a probe beam by a strong background field, and compare it with a recent worldline expression for the photon polarisation flip amplitude. When the probe and the background are plane waves, the ellipticity is equal to the flip amplitude. Here we investigate the ellipticity-amplitude relation for more physical fields.
