Daniel Comparat (DR CNRS, LAC MFC coordinator) works on cold atoms, molecules and Rydberg physics. Research: (1) Rydberg atoms — spectroscopy, few-body interactions, frozen Rydberg gases with Cs/Yb; (2) cold molecules — BaF laser cooling and trapping for eEDM measurement; (3) antihydrogen laser manipulation for fundamental tests; (4) novel electron electric dipole moment measurement technique; (5) cold ion and electron sources (photo-ionization of laser-cooled atoms). ERC-linked funding.

Doyle's group laser-cools and traps polyatomic and diatomic molecules (including CaF and YbOH) using cryogenic buffer-gas sources, applying them to precision tests of fundamental physics such as the electron electric dipole moment (ACME-style eEDM measurement) and to molecule-based quantum information. This precision-measurement approach to fundamental-symmetry tests is a borderline but included case under the quantum-sensing umbrella, given its shared cold-molecule-platform lineage with atomic/vapor sensing and inertial-sensing work.

Fan is a junior faculty member specializing in searches for physics beyond the Standard Model through precision measurements using ion traps and molecules. Included as a borderline quantum-sensing/precision-measurement case, analogous to eEDM-style molecular and ion-trap metrology elsewhere in the department.
