Numerous astrophysical and cosmological observations are best explained by the existence of dark matter, a mass density which interacts only very weakly with visible, baryonic matter. Searching for the extremely weak signals produced by this dark matter strongly motivate the development of new, ultra-sensitive detector technologies. Paradigmatic advances in the control and readout of massive mechanical systems, in both the classical and quantum regimes, have enabled unprecedented levels of sensitivity. In this white paper, we outline recent ideas in the potential use of a range of solid-state mechanical sensing technologies to aid in the search for dark matter in a number of energy scales and with a variety of coupling mechanisms.

暗物质的存在可以最好地解释许多天体和宇宙学观测，暗物质是一种质量密度，仅与可见的重子物质相互作用很小。寻找由这种暗物质产生的极微弱的信号，有力地促进了新的超灵敏探测器技术的发展。在经典和量子状态下，大型机械系统的控制和读出的范式进步已实现了前所未有的灵敏度。在本白皮书中，我们概述了潜在使用的一系列固态机械传感技术的最新想法，这些技术可以在许多能级和多种耦合机制下帮助寻找暗物质。
