Quantum Processes Group

The Quantum Processes Group develops theory and models of atomic, molecular, and condensed matter processes. The group is interested in the dynamic and static properties of these systems and how these systems interact with optical and magnetic fields. The goals of these fundamental studies are directed towards improved physical measurements, enhanced nanoscale measurement, and quantum coherent devices.
