暗物质轴子搜索与环腔实验（DANCE）被提出来搜索轴子暗物质[Phys。莱特牧师。 121, 161301 (2018)]。我们的目标是检测由轴子-光子与领结腔耦合引起的光学线性偏振的旋转和振荡。与目前最好的上限相比，DANCE 可以将轴子质量 ma < 10−10 eV 的轴子-光子耦合常数 gaγ 的灵敏度提高几个数量级。原型实验 DANCE Act-1 正在进行中，以证明该方法的可行性并研究技术噪音。组装光学器件并评估腔体的性能。第一次为期12天的观测于2021年5月成功进行。我们在10 Hz处达到了线偏振旋转角的单侧振幅谱密度3×10−6rad/Hz。
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 gaγ for axion mass ma < 10−10 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 3×10−6rad/Hz at 10 Hz in the one-sided amplitude spectral density of the rotation angle of linear polarization.
