论文摘要
研究了使用高频GWS的电磁（EM）探测器检测带有行星质量原始黑洞（PBH）二进制的引力波（GW）的可能性。我们根据基于Gertsenshtein逆效应的两种专利的实验设计，其中传入的GW通过静态磁场诱导TM腔或TEM波导内部的EM激发。计算用于牛顿后GW波形的检测器的频率响应。我们发现，基于当前技术的此类EM检测器可能会达到应变敏感性，低至$ h \ sim 10^{ - 30} $，它产生了$ 10^{ - 10} $ W的EM功率变化。这允许检测到PBH二进制质量合并，以$ 10^{ - 5} m_ \ odot $ 0.0 $ 0.0 $ 0.01 $ ats Indutiate $ 10^$ 10^{ - 5} $ WIAND INDITION $ 0.01 $ 0.01 $ 0.观察。我们设想，这类探测器也可以用于检测早期宇宙中宇宙学的背景和探测源，直至肠道量表。
The possibility to detect gravitational waves (GW) from planetary-mass primordial black hole (PBH) binaries with electromagnetic (EM) detectors of high-frequency GWs is investigated. We consider two patented experimental designs, based on the inverse Gertsenshtein effect, in which incoming GWs passing through a static magnetic field induce EM excitations inside either a TM cavity or a TEM waveguide. The frequency response of the detectors is computed for post-newtonian GW waveforms. We find that such EM detectors based on current technology may achieve a strain sensitivity down to $h \sim 10^{-30}$, which generates an EM power variation of $10^{-10}$ W. This allows the detection of PBH binary mergers of mass around $10^{-5} M_\odot$ if they constitute more than $0.01$ percent of the dark matter, as suggested by recent microlensing observations. We envision that this class of detectors could also be used to detect cosmological GW backgrounds and probe sources in the early Universe at energies up to the GUT scale.
