In a recent study published in the journal National Science Review , a laboratory search was conducted using a collection NV diamond magnetometer to perform a laboratory search on singular spin-dependent interactions. New experimental constraints on two singular interactions are established on the micron scale.
Particle Physics 's standard model cannot explain some observations in current cosmic astronomy, such as dark matter and dark energy. Scientists believe that outside the standard model, there may be new particles that can serve as a medium for propagating new singular spin-dependent interactions.
In recent years, the research team has developed the use of quantum sensors in diamonds to accurately measure strange interactions, so as to find possible new particles in the laboratory. In this work, the researchers expanded from a single quantum sensor in a diamond to an integrated quantum sensor, greatly improving detection sensitivity.
They implemented laboratory tests of singular spin-dependent interactions between polarized electrons and non-polarized nucleons and established new experimental constraints on the micron scale.
This work demonstrates the unique advantages and potential of diamond quantum precision measurement technology in exploring basic physical problems such as new particles and new interactions.
