Chinese researchers at the University of Science and Technology of China, as part of the Chinese Academy of Sciences, have made significant strides in the field of particle physics. Using solid-state spin quantum sensors, the research team led by Academician Du Jiangfeng and Professor Rong Xing, in collaboration with Professor Jiao Man from Zhejiang University, explored new particle interactions at microscale distances, pushing the boundaries of the Standard Model.
Their study, published in Physical Review Letters, delves into exotic spin-spin-velocity-dependent interactions at short force ranges. The Standard Model, while successful in describing fundamental particles and interactions, falls short in explaining key cosmological phenomena like dark matter and dark energy.
The research team’s experimental setup involved utilizing two diamonds with high-quality nitrogen-vacancy ensembles. By manipulating spin quantum states and relative velocities of the NV ensembles, they sought out new interaction effects between the velocity-dependent spin of electrons on a micrometer scale. Through meticulous measurements and analysis, they were able to uncover valuable data on these interactions within specific force ranges.
The findings of this study offer fresh insights into fundamental physics, paving the way for further exploration in quantum sensing. The researchers’ innovative approach provides a solid foundation for investigating fundamental interactions using solid-state spins in a compact, flexible, and sensitive manner.
This groundbreaking research not only expands our understanding of particle interactions at a quantum level but also opens up possibilities for future discoveries in the field of physics. By pushing the boundaries of the Standard Model and investigating new interactions between electron spins, this study marks a significant advancement in our quest to unravel the mysteries of the universe.
