摘要:
本文提出了一种利用约瑟夫森结开关电流探测器(JJSCD)探测随机引力波背景(SGWB)的方法。该探测器对剪切波的灵敏度现实上可达到 $h\simeq 10^{-19}$,在近期未来可达到 $10^{-21}$,乐观估计可达到 $10^{-24}$。若利用频率比带来的增强因子,有可能进一步低于大爆炸核合成(BBN)界限。若能触及该区域,将有望发现新物理的痕迹。
英文摘要:
In this paper, we propose a method to probe a Stochastic Gravitational Wave Background (SGWB) with Josephson Junction Switching Current Detector (JJSCD). The sensitivity for the shear can reach $h\simeq 10^{-19}$ realistically, $10^{-21}$ in the near future, $10^{-24}$ optimistically. If we utilize the enhancement factor from the ratio of the frequency, it is possible to reach further below the Big Bang Nucleosynthesis (BBN) bound. It will be interesting if we can access the region to discover a footprint of new physics.
