脉冲光场中光传播的干涉测量
Interferometry of light propagation in pulsed fields
摘要:
我们调查使用地面引力波干涉仪的强场域的QED的研究。利用干涉法测量磁场中量子涨落引起的相速度移动可以成为研究宏观电磁场之间非线性自相互作用的灵敏探针。我们确定脉冲磁铁作为一个合适的强场源,因为它们的脉冲频率可以完美地匹配的最高灵敏度的引力波干涉仪的域。如果这些干涉仪达到未来的灵敏度目标,不仅可以发现强场QED现象,而且还可以访问假设的隐藏扇区粒子的进一步参数空间。
英文摘要:
We investigate the use of ground-based gravitational-wave interferometers for studies of the strong-field domain of QED. Interferometric measurements of phase velocity shifts induced by quantum fluctuations in magnetic fields can become a sensitive probe for nonlinear self-interactions among macroscopic electromagnetic fields. We identify pulsed magnets as a suitable strong-field source, since their pulse frequency can be matched perfectly with the domain of highest sensitivity of gravitational-wave interferometers. If these interferometers reach their future sensitivity goals, not only strong-field QED phenomena can be discovered but also further parameter space of hypothetical hidden-sector particles will be accessible.
