论文摘要
搜索超出标准模型的物理学对于理解宇宙的奥秘（例如暗物质）至关重要。我们利用钻石中的单个自旋作为传感器来探索由轴突样颗粒介导的自旋依赖性相互作用，这些相互作用是由候选暗物质候选者充分动机的。我们记录了来自移动质量的单电子自旋上施加的非零磁场。磁场的强度与移动质量的速度成正比。磁场对自旋质量和运动质量之间距离的依赖性已实验表征。我们分析了该磁信号的可能来源，我们的结果极大地暗示了存在新的自旋依赖性相互作用。我们的工作为研究实验室标准模型以外的物理学开了一扇门。
Searching for physics beyond the standard model is crucial for understanding the mystery of the universe, such as the dark matter. We utilized a single spin in a diamond as a sensor to explore the spin-dependent interactions mediated by the axion-like particles, which are well motivated by dark matter candidates. We recorded non-zero magnetic fields exerted on the single electron spin from a moving mass. The strength of the magnetic field is proportional to the velocity of the moving mass. The dependency of the magnetic field on the distance between the spin and the moving mass has been experimentally characterized. We analyzed the possible sources of this magnetic signal, and our results provide highly suggestive of the existence of a new spin-dependent interaction. Our work opens a door for investigating the physics beyond the standard model in laboratory.
