轴子暗物质对圆偏振光子的相速度进行微分。在[Phys. Rev. Lett. 123，111301（2019）]，我们提出了一种通过使用线性光学腔来测量相位差的方案。如果将该方案应用于先进LIGO类的Fabry-Perot臂（类宇宙探测器）引力波探测器，对轴子-光子耦合常数g aγ的潜在灵敏度，达到g aγ 8 × 10−13 GeV−1（4 × 10−14 GeV−1），轴子质量m = 3 × 10−13 eV（2 × 10−15 eV），并在质量的3个数量级保持在这个灵敏度附近。此外，它的灵敏度在m = 1.563 × 10− 10 eV（1.563 × 10 − 11 eV）处有一个尖锐的峰值，达到g aγ <$10 −14 GeV−1（8 × 10−17 GeV−1）。这种灵敏度可以在不损失对引力波的任何灵敏度的情况下实现。
Axion dark matter differentiates the phase velocities of the circular-polarized photons. In [Phys. Rev. Lett. 123, 111301 (2019)], we have proposed a scheme to measure the phase difference by using a linear optical cavity. If the scheme is applied to the Fabry-Perot arm of Advanced LIGO-like (Cosmic-Explorer-like) gravitational wave detector, the potential sensitivity to the axion-photon coupling constant, g aγ, reaches g aγ ≃ 8 × 10−13 GeV−1 (4 × 10−14 GeV−1) at the axion mass m ≃ 3 × 10−13 eV (2 × 10−15 eV) and remains at around this sensitivity for 3 orders of magnitude in mass. Furthermore, its sensitivity has a sharp peak reaching g aγ ≃ 10−14 GeV−1 (8 × 10−17 GeV−1) at m = 1.563 × 10−10 eV (1.563 × 10−11 eV). This sensitivity can be achieved without loosing any sensitivity to gravitational waves.
