Atomic, Molecular, and Optical Physics

Theory: Charge exchange collisions; fine-structure changing collisions; optical processes in gases; molecular hyperfine spectroscopy. (Hickman)
Experiment: Collisional processes in atomic vapors including excitation transfer and “energy pooling” line-broadening, quenching, diffusion, resonance exchange and velocity-changing collisions; molecular spectroscopy of bound singlet and triplet states of alkali diatomics, photodissociation, predissociation, and bound-free emission. (Huennekens, Kim) Transport and thermodynamic properties of superfluid Fermi gases, photonic quantum materials, Rydberg polaritons, and ultracold bialkali molecules. (Sommer)
