摘要:

量子电动力学预言量子真空是双折射的,但由于横截面非常小,这还有待实验证实。真空双折射是光子-光子散射的弹性部分,非弹性部分是Breit-Wheeler对产生。我们概述了如何测量的光子偏振的非线性Breit-Wheeler过程可以用来推断测量的非线性真空双折射。作为一个例子的情况下,我们计算这样的测量的准确性,预计在即将到来的激光粒子实验的参数。

英文摘要:

Quantum electrodynamics predicts that the quantum vacuum is birefringent, but due to the very small cross-section this is yet to be confirmed by experiment. Vacuum birefringence arises as the elastic part of photon-photon scattering; the inelastic part is Breit-Wheeler pair-production. We outline how measurements of the photon-polarised nonlinear Breit-Wheeler process can be used to infer a measurement of nonlinear vacuum birefringence. As an example scenario, we calculate the accuracy of such a measurement for parameters anticipated at upcoming laser-particle experiments.
