Axions and axionlike particles are strongly motivated dark-matter candidates that are the subject of many current ground based dark-matter searches. We present first results from the Axion Dark-Matter Birefringent Cavity (ADBC) experiment, which is an optical bow-tie cavity probing the axion-induced birefringence of electromagnetic waves. Our experiment is the first optical axion detector that is tunable and quantum noise limited, making it sensitive to a wide range of axion masses. We have iteratively probed the axion mass ranges 40.9–43.3neV/c2, 49.3–50.6 neV/c2, and 54.4–56.7 neV/c2, and found no dark-matter signal. On average, we constrain the axionlike particle and photon coupling at the level gaγγ≤1.9×10−8 GeV−1. We also present prospects for future axion dark-matter detection experiments using optical cavities.

轴子暗物质双折射腔（ADBC）实验的初步结果

轴子和轴子样粒子是强烈激发的暗物质候选者，是当前许多基于地面的暗物质搜索的主题。我们提出了轴子暗物质双折射腔（ADBC）实验的初步结果，该实验是一个光学蝴蝶结腔，用于探测轴离子诱导的电磁波双折射。我们的实验是第一个可调谐且量子噪声受限的光学轴子探测器，使其对广泛的轴子质量敏感。我们迭代探测了轴子质量范围 40.9–43.3neV/c2、49.3–50.6 neV/c2 和 54.4–56.7 neV/c2，没有发现暗物质信号。平均而言，我们将轴子状粒子和光子耦合限制在 gaγγ≤1.9×10−8 GeV−1 水平。我们还为未来使用光学腔的轴子暗物质探测实验提供了前景。美国物理学会 2024 年出版
