论文摘要
由于通货膨胀阶段的地平线，早期宇宙的随机重力波背景的截止频率接近100 MHz。为了在这种频率下检测引力波，共振电磁腔非常适合。在这项工作中，我们研究了此类探测器的频率敏感性，并展示了如何使用它们来探测此截止频率以及此随机背景的每个频率的能量密度。本文为进一步的实验研究铺平了道路，以探究宇宙中最古老的遗物。
Stochastic gravitational wave background from the early Universe has a cut-off frequency close to 100 MHz, due to the horizon of the inflationary phase. To detect gravitational waves at such frequencies, resonant electromagnetic cavities are very suitable. In this work, we study the frequency sensitivity of such detectors, and show how we could use them to probe this cut-off frequency and also the energy density per frequency of this stochastic background. This paper paves the way for further experimental studies to probe the most ancient relic of the Universe.
