论文摘要
涉及自旋和巨大粒子之间标量耦合的单极 - 偶极相互作用违反了P和T-对称性，并且可以通过轴介导。我们使用$^{129} $ XE-$^{131} $ XE-RB原子细胞comagnetometer来测量两个XENON同位素之间的进动频率的比率，并且搜索比率的变化与原子Bimagnetic Bimentic Bimentic Bismuthate dermanate（BGO）（BGO）cyressal（BGO）。调制的RB极化方案用于抑制两个数量级的系统效应。此搜索的无效结果改善了耦合强度的上限$ g_ {s}^ng_ {p}^{n} $在0.11-0.55 mm上，并在0.24毫米时的最大改进因子为30。该新的排除区域的相应繁殖质量范围覆盖0.36-1.80 MEV。
Monopole-dipole interactions involving scalar couplings between a spin and a massive particle violate both P- and T-symmetry, and can be mediated by axions. We use a $^{129}$Xe-$^{131}$Xe-Rb atomic cell comagnetometer to measure the ratio of precession frequencies between the two xenon isotopes, and search for changes of the ratio correlated with the distance between the atomic cell and a non-magnetic bismuth germanate (BGO) crystal. A modulated Rb polarization scheme is used to suppress systematic effects by two orders of magnitude. The null results of this search improve the upper limit on the coupling strength $g_{s}^Ng_{p}^{n}$ over the interaction range 0.11 - 0.55 mm, and by a maximum improvement factor of 30 at 0.24 mm. The corresponding propagator mass range of this new excluded region covers 0.36 - 1.80 meV.
