我们描述了一种基于精密磁力测量的方法，该方法可以将对轴子介导的自旋相关力的搜索扩展几个数量级。通过结合核磁共振和短距离重力测试中使用的技术，我们的方法可以大大提高天体物理学目前的实验极限，并深入探讨Peccei-Quinn（PQ）轴子理论上有趣的机制。我们的方法对10（9）和10（12）GeV之间的PQ轴子衰变常数或10（-6）和10（-3）eV之间的轴子质量敏感，与宇宙轴子丰度无关。
We describe a method based on precision magnetometry that can extend the search for axion-mediated spin-dependent forces by several orders of magnitude. By combining techniques used in nuclear magnetic resonance and short-distance tests of gravity, our approach can substantially improve upon current experimental limits set by astrophysics, and probe deep into the theoretically interesting regime for the Peccei-Quinn (PQ) axion. Our method is sensitive to PQ axion decay constants between 10(9) and 10(12) GeV or axion masses between 10(-6) and 10(-3) eV, independent of the cosmic axion abundance.
