论文摘要
暗物质是我们宇宙的主要组成部分,而斧头是主要候选人。在本文中,可以表明,通过利用轴承诱导的磁性磁化和法拉第效应,质量范围$ 500 $至$ 5000〜μ $ ev的轴支轴,其中一部分($> 3500〜μ $ ev)目前无法使用实验,可以搜索使用现有技术的实验设置。将磁杆放置在高技巧光学腔内,通过将探头限制在内部的光腔中增加了相互作用的时间,从而增强了法拉第效应。这可以充分旋转探针光的极化平面,并产生强大的信号。使用直流磁场选择不同质量的轴。通过在无噪声环境中使用易于可用的高量子效率($ \ \ \ \ \ \ \ 1 $)计数器计数光子域中的光子来进行检测。还提出了一种可以提供有关要搜索的轴的光谱信息的光学干涉方案。
Dark matter is a major constituent of our universe and the axion is a prime candidate. In this article, it is shown that by exploiting the axion induced magnetization in a magnetic rod and the Faraday effect, axions in the mass range $500$ to $5000~μ$eV, a part of which ($> 3500~μ$eV) is currently inaccessible to experiments, can be searched for using the same experimental setup in a year using the existing technologies. The magnetic rod is placed inside a high finesse optical cavity, which by confining the probe light inside it increases the interaction time and thus enhances the Faraday effect. This rotates the plane of polarization of the probe light sufficiently and produces a robust signal. Axions of different mass are selected using a dc magnetic field. Detection is carried out by counting photons in the optical domain using a readily available and high quantum efficiency ($\approx 1$) photon counter in a noise-free environment. An optical interferometric scheme that could provide spectroscopic information about the axion to be searched is also proposed.
