Precision measurments with spin magnetometers

本项目在精密测量方面的重点是使用双磁强计完成CPT（电荷-宇称-时间）和洛伦兹不变性的测试。这个实验可以揭示量子引力效应的迹象，例如时空的各向异性或非交换性。此外，还将继续进行一项利用液态氘-129寻找永久电偶极矩（EDM）的实验。一个有限的EDM将是一个超越标准模型的CP（电荷-宇称）违反的签名。更广泛的影响涉及从K-12到博士后的各级教育以及医学成像的应用。

This project in precision measurements focuses on the completion of a test of CPT (Charge-Parity-Time) and Lorentz invariance using a dual magnetometer. This experiment could reveal the sign of quantum gravity effects, such as anisotropy or non-commutativity of space-time. In addition, an experiment searching for a permanent electric dipole moment (EDM) using liquid Xe-129 will be continued. A finite EDM would be a signature of CP (Charge-Parity) violation beyond the Standard Model. The broader impact involves education at all levels from K-12 to post-doctoral as well as applications to medical imaging.
