First results from the Axion Dark-Matter Birefringent Cavity (ADBC) experiment

Abstract

Axions and axion-like 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 range 40.9-43.3${\text{ neV/c}}^2$, 49.3-50.6${\text{ neV/c}}^2$, and 54.4-56.7${\text{ neV/c}}^2$, and found no dark matter signal. On average, we constrain the ALP-photon coupling at the level $g_{a\gamma \gamma }\le 1.9\times 10^{-8}{\text{ GeV}}^{-1}$. We also present prospects for future axion dark matter detection experiments using optical cavities.
