Professors Peng Xinhua and Jiang Min, from the Spin Resonance Laboratory at the University of Science and Technology of China (USTC), have achieved remarkable advancements in the realm of spin quantum precision measurement. Leveraging a combination of quantum precision measurement, nuclear magnetic resonance (NMR), and optimal filtering techniques, they have conducted exhaustive experiments to explore various spin interactions beyond the Standard Model. The outcomes of these experiments demonstrate an enhancement of at least 17 orders of magnitude in the international detection limit within the specified observation window. This groundbreaking work was published in the prestigious international academic journal Physical Review Letters on June 2, under the title "Limits on Anomalous Spin-Spin Interactions Using Noble-Gas Nuclear Magnetic Resonance".
