Xing Fan

Xing Fan specializes in searching for physics beyond the Standard Model through precision measurements using ion traps and molecules.

Fan will be working on electron and positron Penning ion traps for matter-antimatter symmetry tests and axion searches. His goal is to perform quantum-logic spectroscopy (QLS) of an electron and positron in Penning traps for the first time. The group plans to entangle particles in two remote traps for QLS, with the intention of achieving the most stringent CPT test in the lepton sector. These entangled electrons in Penning traps could also serve as a new platform for quantum information science.

Additionally, Fan will combine ion traps with molecules to search for a nuclear Schiff Moment. By combining the ion manipulation techniques and quantum control of the molecule’s states, the group will perform a sensitive search using rare, octupole-deformed nuclei. Key techniques include buffer-gas cooling of molecular ions, quantum control of their hyperfine states, and nondestructive detection of internal states. 

Fan intends to utilize next-generation approaches for exploring physics beyond the Standard Model, with the help of precision measurement techniques and the opportunity provided by the nuclear physics facilities.
