摘要:

轴子暗物质对圆偏振光的相速度进行微分。本文提出了一种利用线性光腔测量相位差的方案。如果将该方案应用于先进LIGO类(类宇宙探测器)引力波探测器的法布里-珀罗臂,则在轴子质量为$m \simeq 3\times 10^{-13}$ eV($2\times10^{-15}$ eV)时,对轴子-光子耦合常数$g_{\text{a}γ}$的潜在灵敏度达到$g_{\text{a}γ} \simeq 8\times10^{-13}$ GeV $^{-1}\, (4 \times 10^{-14}$ GeV $^{-1})$,并在质量为3个数量级时保持在该灵敏度附近。此外,其灵敏度在$m = 1.563\times10^{-10}$ eV($1.563\times10^{-11}$ eV)处具有达到$g_{\text{a}γ} \simeq 10^{-14}$ GeV $^{-1}$ $(8\times10^{-17}$ GeV $^{-1})$的尖锐峰值。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。

英文摘要:

Axion dark matter differentiates the phase velocities of the circular-polarized photons. In this Letter, a scheme to measure the phase difference by using a linear optical cavity is proposed. If the scheme is applied to the Fabry-Pérot arm of Advanced LIGO-like (Cosmic-Explorer-like) gravitational wave detector, the potential sensitivity to the axion-photon coupling constant, $g_{\text{a}γ}$, reaches $g_{\text{a}γ} \simeq 8\times10^{-13}$ GeV$^{-1}\, (4 \times 10^{-14}$ GeV$^{-1})$ at the axion mass $m \simeq 3\times 10^{-13}$ eV ($2\times10^{-15}$ eV) and remains at around this sensitivity for 3 orders of magnitude in mass. Furthermore, its sensitivity has a sharp peak reaching $g_{\text{a}γ} \simeq 10^{-14}$ GeV$^{-1}$ $(8\times10^{-17}$ GeV$^{-1})$ at $m = 1.563\times10^{-10}$ eV ($1.563\times10^{-11}$ eV). This sensitivity can be achieved without loosing any sensitivity to gravitational waves.
