David DeMille

David DeMille is an American physicist and Professor of Physics at Yale University. He is best known for his use of polar diatomic molecules to amplify symmetry-violating effects within the molecules and as a means for manipulating the external properties of the molecules.

His group was the first to accomplish laser cooling of a diatomic molecule, achieved in 2010 using strontium monofluoride (SrF). He is also known for his precise measurement of the electron electric dipole moment using a beam of thorium monoxide, conducted in collaboration with the groups of Gerald Gabrielse and John Doyle at Harvard. DeMille is currently also leading the CeNTREX collaboration, an experiment to measure the nuclear Schiff moment of the thallium nucleus inside a thallium fluoride molecule.

He was elected a fellow of the American Physical Society in 2005.
