论文摘要
在这项工作中，我们提出了极化实验，以搜索低质量（sub-ev）骨磁场暗物质，包括轴和轴突样颗粒。我们表明，由Fabry-Pérot腔中的厚双重固体组成的极化构型对标量场暗物质非常敏感，这可能会导致固体厚度和折射率的振荡变化。此外，我们表明了该极化实验的重新配置，其中将两个四分之一波板放置在Fabry-Pérot腔内，而不是厚的双折射固体，对轴状颗粒非常敏感。我们研究了使用双极仪的互相关以增加实验的灵敏度的可能性，这反过来又可以探索参数空间的未开发部分，并在任何一个暗物质方案中都可能检测信号。
In this work, we propose polarimetry experiments to search for low-mass (sub-eV) bosonic field dark matter, including axions and axion-like particles. We show that a polarimetry configuration consisting of a thick birefringent solid inside a Fabry-Pérot cavity is exceptionally sensitive to scalar field dark matter, which may cause oscillatory variations in the solid's thickness and refractive index. In addition, we show that a reconfiguration of this polarimetry experiment, in which two quarter-wave plates are placed inside the Fabry-Pérot cavity instead of a thick birefringent solid, is very sensitive to axion-like particles. We investigate the possibility of using cross-correlation of twin polarimeters to increase the sensitivity of the experiment, which in turn could allow us to explore unexplored parts of the parameter space and potentially detect a signal in either dark matter scenario.
