论文摘要
量子电动力学预测量子真空是双重的，但是由于横截面很小，这尚未通过实验确认。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成对生产。我们概述了如何使用光子偏振的非线性BREIT轮毂工艺的测量值来推断非线性真空双折射的测量。作为示例场景，我们计算了在即将进行的激光粒子实验中预期的参数的这种测量的准确性。
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.
