全光环境下的真空双折射探测

Vacuum birefringence detection in all-optical scenarios

Stefan Ataman

摘要:

在本文中,我们提出了一个全光学真空双折射实验,并评估其可行性的各种情况下。许多拍瓦级激光器投入使用,预计在不久的将来还会有更多的激光器投入使用,因此,将有前所未有的电磁场($E_L\sim10^{14}-10^{15}$ V/m和强度$I_L\sim10^{21}-10^{23}$ W/cm $^2$)可用于实验。在我们的提议中,一个拍瓦级的激光器干扰量子真空,并在反向传播的探测激光束中产生延迟。将此延迟光束放置在马赫-曾德尔干涉仪(MZI)的一个臂中,允许通过相移测量真空折射系数。相干光和压缩光都被认为是最小的相位灵敏度评估。我们表明,使用现有的技术和一些适度乐观的假设,至少部分讨论的情况是可行的真空双折射检测实验。

英文摘要:

In this paper we propose an all-optical vacuum birefringence experiment and evaluate its feasibility for various scenarios. Many petawatt-class lasers became operational and many more are expected to enter operation in the near future, therefore unprecedented electromagnetic fields ($E_L\sim10^{14}-10^{15}$ V/m and intensities $I_L\sim10^{21}-10^{23}$ W/cm$^2$) will become available for experiments. In our proposal a petawatt-class laser disturbs the quantum vacuum and creates a delay in a counter-propagating probe laser beam. Placing this delayed beam in one arm of a Mach-Zehnder interferometer (MZI), allows the measurement of the vacuum refraction coefficient via a phase shift. Coherent as well as squeezed light are both considered and the minimum phase sensitivity evaluated. We show that using existing technology and with some moderately optimistic assumptions, at least part of the discussed scenarios are feasible for a vacuum birefringence detection experiment.
