论文摘要
基本粒子的质量和耦合常数等基本常数可以在标量场暗物质模型中具有较小的时间和空间变化。这些变化需要其他常数的时间振荡，例如Bohr和核磁子，Bohr半径以及超细结构常数。在存在外部磁场的情况下，这些振荡诱导原子和分子中的超精细转变。我们确定由振荡基本常数引起的磁偶极性超精细转变的概率，并提出了一个可以通过这种效果检测标量场暗物质的实验。该实验可能对标量场和轴线暗物质敏感，质量在$ 1 \，μ\ text {ev} <m <100 \，μ\ text {ev} $。
Fundamental constants such as masses and coupling constants of elementary particles can have small temporal and spatial variations in the scalar field dark matter model. These variations entail time oscillations of other constants, such as the Bohr and nuclear magnetons, Bohr radius and the hyperfine structure constant. In the presence of an external magnetic field, these oscillations induce hyperfine transitions in atoms and molecules. We determine the probability of magnetic dipole hyperfine transitions, caused by the oscillating fundamental constants, and propose an experiment that could detect the scalar field dark matter through this effect. This experiment may be sensitive to the scalar field and axion dark matter with mass in the range $1\,μ\text{eV}<m<100\,μ\text{eV}$.
