First observation and analysis of DANCE: Dark matter Axion search with riNg Cavity Experiment

Abstract

Dark matter Axion search with riNg Cavity Experiment (DANCE) was proposed to search for axion dark matter [Phys. Rev. Lett. 121, 161301 (2018)]. We aim to detect the rotation and oscillation of optical linear polarization caused by axion-photon coupling with a bow-tie cavity. DANCE can improve the sensitivity to axion-photon coupling constant $g_{a\gamma }$ for axion mass $m_a<10^{-10}\mathrm{eV}$ by several orders of magnitude compared to the best upper limits at present. A prototype experiment DANCE Act-1 is ongoing to demonstrate the feasibility of the method and to investigate technical noises. The optics was assembled and the performance of the cavity was evaluated. The first 12-day observation was successfully performed in May 2021. We reached $3\times 10^{-6}rad/\sqrt{\mathrm{Hz}}$ at $10\mathrm{Hz}$ in the one-sided amplitude spectral density of the rotation angle of linear polarization.
