论文摘要
外来自旋依赖性力的存在可能会在标准模型以外的新物理学上发光。我们利用两个铁屏蔽的SMCO $ _5 $电子旋转源和两个光学泵送磁力计来搜索异国情调的长距离自旋旋转速度依赖性力。自旋源和磁力仪的方向优化,以增强外来力,并有效减去共同模式噪声。我们将质子电子相互作用的直接限制设置在力范围从1 \,cm到1 \,km。我们的实验比以前的工作代表了十多个数量级的改进。
The existence of exotic spin-dependent forces may shine light on new physics beyond the Standard Model. We utilize two iron shielded SmCo$_5$ electron-spin sources and two optically pumped magnetometers to search for exotic long-range spin-spin-velocity-dependent force. The orientations of spin sources and magnetometers are optimized such that the exotic force is enhanced and common-mode noise is effectively subtracted. We set direct limit on proton-electron interaction in the force range from 1\,cm to 1\,km. Our experiment represents more than ten orders of magnitude improvement than previous works.
