Precision measurement, atomic EDM measurement, quantum information, spin polarized atoms
Violations of symmetries in fundamental interactions are important in understanding the universe，for example, the imbalance of matter and antimatter. These violations will cause non-zero atomic EDM, which is usually difficult to detect. We will use some specific isotopes as candidates to perform atomic EDM measurements. These isotopes have bigger stronger nuclear distortion, so they have better sensitivity of new physics beyond standard model. The technical challenge is suppression of the statistical error in the measurement.
