论文摘要
预计轴突样颗粒（阿尔卑斯山）将介导自旋和质量之间的外来相互作用。我们提出了一个基于悬浮的微机械振荡器的ALP搜索实验，该实验是短距离的自旋质量力最敏感的传感器之一。提出的实验测试了极化电子旋转与透明的悬浮微球之间的自旋质量谐振相互作用。通过定期翻转电子旋转，可以消除非共振背景力的污染。悬浮的微观激光滤器可以前瞻性地提高敏感性近10美元^3 $倍，比目前的实验对阿尔卑斯山的质量为4 MeV至0.4 eV。
Axion-like particles (ALPs) are predicted to mediate exotic interactions between spin and mass. We propose an ALP-searching experiment based on the levitated micromechanical oscillator, which is one of the most sensitive sensors for spin-mass forces at a short distance. The proposed experiment tests the spin-mass resonant interaction between the polarized electron spins and a diamagnetically levitated microsphere. By periodically flipping the electron spins, the contamination from nonresonant background forces can be eliminated. The levitated microoscillator can prospectively enhance the sensitivity by nearly $10^3$ times over current experiments for ALPs with mass in the range 4 meV to 0.4 eV.
