我们提出了一种用光学环腔来寻找轴子暗物质的新方法。莱特牧师。121,161301(2018年)]。光子与轴子或轴子状粒子的耦合使左旋和右旋光子的相速度发生调制差异。我们的方法是用环形腔通过测量两个圆偏振之间的共振频率差来测量这种相速度差。我们的估算表明，对于轴子质量mγ10≲10−10 eV，对轴子-光子耦合常数g a的灵敏度可以比目前的最佳极限提高几个数量级。在这篇文章中，我们介绍了环腔暗物质轴子搜索实验(DARY)的原理和原型实验DISE-1的现状。
We have proposed a new approach to search for axion dark matter with an optical ring cavity [Phys. Rev. Lett. 121, 161301 (2018)]. The coupling of photons to axions or axion-like particles makes a modulated difference in the phase velocity between left-and righthanded photons. Our method is to measure this phase velocity difference with a ring cavity, by measuring the resonant frequency difference between two circular polarizations. Our estimation shows that the sensitivity to axion-photon coupling constant g aγ for axion mass m≲ 10− 10 eV can be improved by several orders of magnitude compared with the current best limits. In this paper, we present the principles of the Dark matter Axion search with riNg Cavity Experiment (DANCE) and the status of the prototype experiment, DANCE Act-1.
