基于原子间化学键的断裂，我们探索了一种新的低阈值直接探测暗物质的概念。这包括分子的解离和晶格中缺陷的产生。这种实验的阈值为几到10英尺的电子伏特S，可以探测到光到几MeV的暗物质粒子的核耦合。我们计算暗物质分裂双原子分子的预期速率，我们将其作为更一般系统的案例研究。我们简要地提到了在实践中如何检测化学键断裂的想法。我们还讨论了用这个实验概念探测包括pp中微子在内的太阳中微子的可能性。由于事件发生率为(0.1/kg-年)，需要大曝光，但测量低能太阳中微子将提供对太阳模型的关键测试。
We explore a new low-threshold direct-detection concept for dark matter, based on the breaking of chemical bonds between atoms. This includes the dissociation of molecules and the creation of defects in a lattice. With thresholds of a few to 10's of eV, such an experiment could probe the nuclear couplings of dark matter particles as light as a few MeV. We calculate the expected rates for dark matter to break apart diatomic molecules, which we take as a case study for more general systems. We briefly mention ideas for how chemical-bond breaking might be detected in practice. We also discuss the possibility of detecting solar neutrinos, including pp neutrinos, with this experimental concept. With an event rate of $\mathcal{O}$(0.1/kg-year), large exposures are required, but measuring low-energy solar neutrinos would provide a crucial test of the solar model.
