我们讨论了使用光学腔作为工具来寻找暗物质（DM）组成的维里化超光场（VLLF）。这样的场可能导致振荡的基本常数，导致刚体长度的振荡。我们建议通过刚性和悬挂镜腔的差分应变测量来寻找这些效应。我们估计，在0.1-10 kHz的可听范围内，在VLLF康普顿频率下，可以探测到超过2个数量级的用于VLLF DM耦合的未探索的相空间。
We discuss the use of optical cavities as tools to search for dark matter (DM) composed of virialized ultralight fields (VULFs). Such fields could lead to oscillating fundamental constants, resulting in oscillations of the length of rigid bodies. We propose searching for these effects via differential strain measurement of rigid and suspended-mirror cavities. We estimate that more than 2 orders of magnitude of unexplored phase space for VULF DM couplings can be probed at VULF Compton frequencies in the audible range of 0.1-10 kHz.
