Searching for ultra-light dark matter with optical cavities

Searching for Gravitational Waves with CMS

The idea of searching for gravitational waves using cavities in strong magnetic fields has recently received significant attention. Most concepts foresee moderate magnetic fields in rather small volumes, similar to those which are currently employed for axion-like particle searches. We propose to use the magnet system of the Compact Muon Solenoid (CMS) experiment after the high luminosity phase of the LHC as a key component for a future detector for gravitational waves in the MHz frequency range. In this paper we briefly discuss a possible cavity concept which can be integrated into CMS and ad…

利用光纤寻找标量超轻暗物质

Searching for Scalar Ultralight Dark Matter with Optical Fibers

提出使用由实芯和空芯光纤组成的干涉仪探测质量在 $10^{-17} - 10^{-13}$ eV/$c^2$ 的标量超轻暗物质，通过探测精细结构常数 $α$ 调制引起的折射率相对振荡，结合阵列或低温冷却，该搜索在特定质量范围内的灵敏度超越以往。
