Dr. Xing Wu is an Assistant Professor at the Facility for Rare Isotope Beams (FRIB) and Michigan State University. He received PhD from Max-Planck-Institute of Quantum Optics in Germany. His research is at the intersection of atomic, molecular, and optical (AMO) physics, quantum technology, and nuclear science. Dr. Wu has pioneered advanced techniques for cooling and decelerating molecular beams, and famously achieved a groundbreaking milestone by measuring the most precise bound on the electron electric dipole moment (EDM) using cold molecules as quantum sensors. Currently, his group at FRIB is constructing a next-generation precision spectroscopy experiment. This initiative leverages FRIB’s unique radioactive isotope resources alongside cutting-edge quantum control techniques to test fundamental symmetries and probe new physics beyond the Standard Model.
Presentation Title:
Towards Quantum Control and Sensing with Radioactive Molecules for Fundamental Symmetry Tests
Presentation Abstract:
The Standard Model successfully describes known fundamental particles but cannot explain the Universe’s matter-antimatter asymmetry. Theories beyond the Standard Model address this by predicting massive particles that violate time-reversal (T-) symmetry, generating an electric dipole moment (EDM) along electron and nucleon spins. Searching for an EDM provides a powerful probe into this new physics and sheds light on the origin of the universe. This talk outlines a roadmap for a next-generation EDM measurement designed to outperform current limits in testing hadronic T-violations. We report on ongoing efforts in the quantum control and sensing of 227ThO and other radioactive molecules. These advancements pave the way for quantum-enhanced tests of fundamental symmetry, with projections to constrain T-violating new physics in the 10–100 TeV energy range—exceeding the reach of the Large Hadron Collider and its future upgrades.
