Abstract
Section titled “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, <a:math xmlns:a=“http://www.w3.org/1998/Math/MathML” display=“inline”><a:msub><a:mi>V</a:mi><a:mn>6</a:mn></a:msub></a:math>, new limits on the corresponding coupling coefficient, <c:math xmlns:c=“http://www.w3.org/1998/Math/MathML” display=“inline”><c:msub><c:mi>f</c:mi><c:mn>6</c:mn></c:msub></c:math>, have been established for the force range shorter than 1 cm.
