We propose a search for low mass dark matter particles through momentum recoils caused by their scattering from trapped, nanometer-scale objects. Our projections show that even with a modest array of femtogram-mass sensors, parameter space beyond the reach of existing experiments can be explored. The case of smaller, attogram-mass sensors is also analyzed—where dark matter can coherently scatter from the entire sensor—enabling a large enhancement in the scattering cross-section relative to interactions with single nuclei. Large arrays of such sensors have the potential to investigate new parameter space down to dark matter masses as low as 10 keV. If recoils from dark matter are detected by such sensors, their inherent directional sensitivity would allow an unambiguous identification of a dark matter signal.

来自光学捕获传感器的低质量暗物质的相干散射

我们建议通过由捕获的纳米级物体散射引起的动量反冲来寻找低质量暗物质粒子。我们的预测表明，即使使用适度的飞克质量传感器阵列，也可以探索超出现有实验范围的参数空间。还分析了较小的阿克质量传感器的情况——暗物质可以从整个传感器相干散射——相对于与单核的相互作用，能够大幅增强散射截面。此类传感器的大型阵列有可能研究低至 10 keV 的暗物质质量的新参数空间。如果此类传感器检测到来自暗物质的反冲，它们固有的方向灵敏度将允许明确识别暗物质信号。
