论文摘要
轴线 - 螺旋体相互作用诱导轴和物质场之间的二次耦合。我们发现，如果轴轴是一个超轻的暗物质场，它会诱导黑龙的质量和其他核量的小振荡。结果，原子能水平振荡。我们使用当前可用的原子光谱数据来限制这种轴突 - 螺旋耦合。我们还投射了未来实验的敏感性，例如使用分子和核钟过渡的实验。我们表明，当前和近未实现的实验限制了轴突模型的精细调整参数空间。除了基于不久的将来的基于磁力计的实验外，这些还可以与已振荡的中子电偶极矩和超新星结合的振荡中已经存在的约束或主导已经存在的约束。我们还简要讨论了加速度计和干涉仪的范围。
Axion-gluon interaction induces quadratic couplings between the axion and the matter fields. We find that, if the axion is an ultralight dark matter field, it induces small oscillations of the mass of the hadrons as well as other nuclear quantities. As a result, atomic energy levels oscillate. We use currently available atomic spectroscopy data to constrain such axion-gluon coupling. We also project the sensitivities of future experiments, such as ones using molecular and nuclear clock transitions. We show that current and near-future experiments constrain a finely-tuned parameter space of axion models. These can compete with or dominate the already-existing constraints from oscillating neutron electric dipole moment and supernova bound, in addition to those expected from near future magnetometer-based experiments. We also briefly discuss the reach of accelerometers and interferometers.
