论文摘要
通过单个电子自旋量子传感器，建立了在千分尺尺度上与外来自旋和速度依赖性相互作用结合的改进的实验室。钻石中近表面氮 - 视口中心的单个电子自旋用作量子传感器，并将振动的半球镜头作为移动核子的来源。通过测量电子自旋量子传感器感受到的可能的磁场，探索了极化电子与移动核子源之间的外在相互作用。我们的实验设置了对功率范围内1至330 $μ$ m内的外来自旋和速度依赖性相互作用的改进约束。耦合的上限$ g_a^eg_v^n $ at $ 200〜μm $是$ | g_a^e g_v^n | \ leq 8.0 \ times10^{ - 19} $，将当前的实验室限制显着提高了四个以上的数量级。
n improved laboratory bound on the exotic spin- and velocity-dependent interaction at micrometer scale is established with a single electron spin quantum sensor. The single electron spin of a near-surface nitrogen-vacancy center in diamond is utilized as the quantum sensor and a vibrating half-sphere lens is taken as the source of the moving nucleons. The exotic interaction between the polarized electron and the moving nucleon source is explored by measuring the possible magnetic field felt by the electron spin quantum sensor. Our experiment set improved constraints on the exotic spin- and velocity-dependent interaction within the force range from 1 to 330 $μ$m. The upper limit of the coupling $g_A^eg_V^N $ at $200 ~μm$ is $| g_A^e g_V^N| \leq 8.0\times10^{-19}$, significantly improving the current laboratory limit by more than four orders of magnitude.
