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.
