Xing Fan

Xing Fan is an Assistant Professor of Physics at Harvard University, joining the Department of Physics in July 2025. His research focuses on probing physics beyond the Standard Model through precision measurements using Penning traps, quantum logic spectroscopy, and molecular ion techniques. He specializes in testing CPT symmetry, searching for axions and dark photons, and measuring the electron’s magnetic moment with unprecedented precision.

Education: Ph.D. in Physics from Harvard University (2022), as evidenced by his doctoral thesis titled An Improved Measurement of the Electron Magnetic Moment. His work has been supported by grants from the NSF, DOE (SQMS program), John Templeton Foundation, and Masason Foundation.

Research Interests: Precision measurements of lepton properties, quantum control of trapped particles, Schiff moment searches using thorium isotopes, and developing next-generation detectors for beyond-Standard-Model physics. Notable achievements include advancing quantum logic spectroscopy techniques and proposing entangled lepton systems for CPT symmetry tests.

Awards: Finalist for the DAMOP Deborah Jin Thesis Award (2023) and recipient of the FRIB Visiting Scholar Program (2025). His group’s work bridges particle physics and quantum information science, with applications in both fundamental physics and technology development.

Future Work: Establishing the Fan Research Group at Harvard to explore electron-positron entanglement, milli-eV axion searches, and Schiff moment studies with trapped molecular ions like ThF+. Collaborations include the ACME experiment for eEDM measurements and nuclear physics facilities.
