John Bohn Portrait
Research Professor • JILA Fellow

Office: JILA S377

Research Interests:

My primary research centers on the theory of collisions between trapped atoms and molecules in a dilute gas at milliKelvin temperatures and below. In this novel energy regime, tiny energy splittings (due, for instance, to magnetic interactions or molecular rotations) dominate the collision dynamics. My goal is to unravel these delicate energy exchanges and assess their response to external electromagnetic fields. More broadly, I'm looking for novel approaches to understanding collective motions of many-body quantum-mechanical systems such as electrons in an atom or semiconductor device or atoms in a Bose-Einstein condensate.
