标题： High-Frequency Gravitational Wave Search with ABRACADABRA-10\,cm

摘要： ABRAcadabra-10厘米作为路径finder集总元件轴子暗物质实验取得了巨大成功，在大统一理论（GUT）尺度上限制了轴子暗物质。现在，通过利用引力波与电动力学的相互作用以及读出策略的变化，我们首次使用ABRA-10厘米探测器通过修改后的轴子探测器搜索高频引力波。这些高频（10 kHz到5 MHz）的潜在源包括原始黑洞双星合并或其他超出标准模型的现象。 本文介绍了ABRA-10厘米高频引力波搜索的设计、结果和挑战，展示了同时寻找轴子和高频引力波的可能性，并且两种搜索都达到了理论预期的灵敏度。此外，我们还使用轴子实验的数据进行了第一次时序瞬变搜索，达到了$10^{-4}$的应变灵敏度。 直接扩展到下一代轴子实验DMRadio-GUT，这种灵敏度将意味着在大约3秒差距的距离上可以探测到0.01$M_{\odot}$的原始黑洞合并，通过改进读出方式，有望进一步显著提高探测范围。 显示英文摘要

摘要： ABRACADABRA-10 cm has had great success as a pathfinder lumped-element axion dark matter experiment, setting limits on axion dark matter at the GUT scale. Now, using the interaction of gravitational waves with electrodynamics and a change in readout strategy, we use the ABRA-10 cm detector for the first search for high-frequency gravitational waves using a modified axion detector. Potential sources at these high frequencies (10 kHz to 5 MHz) include merging primordial black hole binaries or superradiance, among other beyond the standard model phenomena. This paper presents the design, results, and challenges from the ABRA-10 cm high-frequency gravitational wave search, showing it is possible to simultaneously look for axions and high-frequency gravitational waves with both searches matching theoretical expectations for sensitivity. Additionally, we conducted the first time series transient search with data from an axion experiment, achieving sensitivity to $10^{-4}$ in strain. Scaled directly to the next generation axion experiment, DMRadio-GUT, this sensitivity would imply a reach to 0.01 $M_{\odot}$ primordial black hole mergers at distances around 3 pc, with prospects to go significantly further with modifications to the readout.
