论文摘要
重力波(GWS)在外部电场和磁场附近产生振荡电磁效应。我们讨论了这种现象,特别着眼于基于集体元素探测器重新解释轴突卤素的结果,该探测器探测了100 kHz-100 MHz范围内的GWS。尽管当前的应变敏感性较弱,但Abracadabra和Shaft的测量已经将界限放在GWS上。但是,我们证明,此类仪器体积的敏感性比例比轴承更快 - 将来将取得快速的进展。没有任何修改,DMRADIO-M $^3 $将具有200 MHz的GW应变灵敏度为$ H \ SIM 10^{-20} $。用于读取诱导磁通量的拾音环的简单修改可以参数增强GW灵敏度,尤其是在较低的频率下。
Gravitational waves (GWs) generate oscillating electromagnetic effects in the vicinity of external electric and magnetic fields. We discuss this phenomenon with a particular focus on reinterpreting the results of axion haloscopes based on lumped-element detectors, which probe GWs in the 100 kHz-100 MHz range. Measurements from ABRACADABRA and SHAFT already place bounds on GWs, although the present strain sensitivity is weak. However, we demonstrate that the sensitivity scaling with the volume of such instruments is significant - faster than for axions - and so rapid progress will be made in the future. With no modifications, DMRadio-m$^3$ will have a GW strain sensitivity of $h \sim 10^{-20}$ at 200 MHz. A simple modification of the pickup loop used to readout the induced magnetic flux can parametrically enhance the GW sensitivity, particularly at lower frequencies.
