用强Laser脉冲探测真空双折射

Detection of Vacuum Birefringence with Intense Laser Pulses

Andre N. Luiten, Jesse C. Petersen

摘要:

我们提出了一种新的技术,有望成为第一个直接检测极化的量子电动力学(QED)真空。该技术基于使用在低色散光学谐振器中循环的超短光脉冲。我们表明,该技术规避了大规模液氦冷却磁体的需要,更重要的是避免了困扰现有实验,利用这些磁体的实验陷阱。光学和激光器性能的可能改进将导致在仅持续几个小时的实验中观察真空偏振的能力。

英文摘要:

We propose a novel technique that promises hope of being the first to directly detect a polarization in the quantum electrodynamic (QED) vacuum. The technique is based upon the use of ultra-short pulses of light circulating in low dispersion optical resonators. We show that the technique circumvents the need for large scale liquid helium cooled magnets, and more importantly avoids the experimental pitfalls that plague existing experiments that make use of these magnets. Likely improvements in the performance of optics and lasers would result in the ability to observe vacuum polarization in an experiment of only a few hours duration.
