Abstract

We report new experimental results on exotic spin-spin-velocity-dependent interactions between electron spins. We designed an elaborate setup that is equipped with two nitrogen-vacancy (NV) ensembles in diamonds. One of the NV ensembles serves as the spin source, while the other functions as the spin sensor. By coherently manipulating the quantum states of two NV ensembles and their relative velocity at the micrometer scale, we are able to scrutinize exotic spin-spin-velocity-dependent interactions at short force ranges. For a T-violating interaction, $V_{6}$ , new limits on the corresponding coupling coefficient, $f_{6}$ , have been established for the force range shorter than 1 cm. For a P,T-violating interaction, $V_{14}$ , new constraints on the corresponding coupling coefficient, $f_{14}$ , have been obtained for the force range shorter than 1 km.
