Scientific research continues to push the boundaries of knowledge, and a recent breakthrough in exploring exotic spin interactions has been made by a team of researchers led by Academician DU Jiangfeng from the University of Science and Technology of China (USTC). Their innovative use of solid-state spin quantum sensors based on nitrogen-vacancy (NV) centers in diamond has opened up new possibilities for investigating these interactions at the microscale.
Unveiling New Insights
The research findings of Academician DU Jiangfeng’s team, which were published in prestigious scientific journals including National Science Review, Physical Review Letters, and Proceedings of the National Academy of Sciences(PNAS), provide valuable insights and experimental constraints on exotic spin interactions. These interactions, induced by new bosons, have become a focus of experimental searches as they offer the potential to address fundamental questions beyond the standard model.
By harnessing the power of diamond NV centers as quantum sensors, the team has successfully constructed high-sensitivity detectors capable of investigating spin interactions between electrons and nuclei. This breakthrough extends the range of experimental searches to sub-micrometer scales, enabling precise measurements of various spin phenomena.
