论文摘要
暗物质是我们宇宙中普通可见物质的五倍。尽管实验室搜索暗物质的搜索传统上关注电动量表，但低质量隐藏部门的理论激发了新的检测技术。将这些搜索扩展到较低的质量范围，远低于1 GEV/C $^2 $，因此提出了新的挑战，因为与标准模型物质转移的罕见相互作用逐渐减少了检测器中对电子和核的能量。在这里，我们提出了一种基于声子辅助量子蒸发的方法，结合了量子传感器，通过跟踪自旋相干性来检测解吸事件。我们提出的暗物质传感器的目的是将参数空间扩展到极少数相互作用的能量传输，以至于低至几mEV，以检测kev/c $^2 $质量范围内的暗物质颗粒。
Dark matter is five times more abundant than ordinary visible matter in our Universe. While laboratory searches hunting for dark matter have traditionally focused on the electroweak scale, theories of low mass hidden sectors motivate new detection techniques. Extending these searches to lower mass ranges, well below 1 GeV/c$^2$, poses new challenges as rare interactions with standard model matter transfer progressively less energy to electrons and nuclei in detectors. Here, we propose an approach based on phonon-assisted quantum evaporation combined with quantum sensors for detection of desorption events via tracking of spin coherence. The intent of our proposed dark matter sensors is to extend the parameter space to energy transfers in rare interactions to as low as a few meV for detection of dark matter particles in the keV/c$^2$ mass range.
