Research in the Doyle group at Harvard is primarily performed in two key areas: i) atomic, molecular, optical (AMO) and quantum and ii) non-accelerator elementary particle physics. Work in AMO/Quantum physics includes production, trapping and evaporative cooling of cold atoms and molecules for use in a variety of experiments including studies of fundamental collisions and chemical reactions, exploration of ultracold quantum gases, and precision optical and microwave spectroscopy. For example, some of the applications developed by the Doyle research group in this area include a new microwave-only technique for the determination of molecular chirality with very high resolution. This discovery has potential applications in pharmaceutical and biotechnology industries as well as in the development of a new sensitive cryogenic complex mixture analyzer for disease diagnostics and industrial use. The research in particle physics centers on the search for the permanent electric dipole moment of the electron (eEDM) using molecules. The work in this area is of fundamental interest to the scientific community because of its potential to discover clear signatures of new fundamental particles at very high energies that would illuminate the cosmic matter-antimatter asymmetry, with vast implications regarding our understanding of the inner workings of the Universe.
