非零电偶极矩的存在意味着对时间反转对称性的破坏。由于标准模型(SM)预测的电子电火花的时间反转对称性破坏太小，无法用现有的实验技术观察到，任何一个非零的EDM都意味着标准模型之外的新物理。电子电火花加工产生的微小信号在Fr等重原子中得到增强。我们正在建设激光冷却Fr工厂，以寻找电子电火花加工。
The existence of a non-zero electric dipole moment (EDM) implies the violation of time reversal symmetry. As the time-reversal symmetry violation predicted by the Standard Model (SM) for the electron EDM is too small to be observed with current experimental techniques and any a non-zero EDM would indicate new physics beyond the SM. The tiny signal from the electron EDM is enhanced in the heavy atoms such as francium (Fr). We are constructing the laser-cooled Fr factory to search for the electron EDM.
