Finding new particles outside the standard model of particle physics is crucial for exploring new physics. The reporter learned from the China University of Science and Technology on February 23 that the key micro-magnetic resonance laboratory of the Chinese Academy of Sciences, led by academician Du Jiangfeng, proposed and implemented a single-electron spin quantum sensor for searching for an axicon, extending the power of search to the submicron scale. . The results were published on the February 21 issue of the journal Nature Communications. In the search for new particles many solutions, a simple and effective theoretical assumption is to introduce a class of ultra-light mass axicon or axon-like particles. It is speculated that these new particles may play a new role in the interaction between electrons and nuclei. Transmission medium. In recent years, scientists have developed a series of sophisticated experimental devices that perform electronic and nuclear interaction searches within a force range of 20 microns or more. However, carrying out experimental research within a shorter range of force has faced a series of challenges such as insufficient size and increased sensitivity. Du Jiangfeng's team used electron spins on the diamond near-surface nitrogen-vacancy (NV) center of color as sensors to search for electron-nuclear interactions in the sub-20 μm range. The team prepared NV color centers within 10 nanometers from the diamond surface as detectors, developed corresponding electronic equipment and quantum control methods, and solved the above-mentioned series of short-range exploration challenges. Experiments have shown that the new sensor can explore a force range of 0.1 μm to 23 μm. This new method can be extended to other spin-related new interaction studies, thus providing the possibility of using single-spin quantum sensors to study new physics beyond the standard model. It is expected to stimulate cosmology, astrophysics, and high-energy physics. A wide range of basic science interests.
