Jin Group Research

Our research focuses on ultracold gases of atoms and molecules. Our experiments use laser cooling, magnetic trapping, and evaporative cooling to reach temperatures below one microKelvin, where quantum statistics dominate the behavior of the atoms or molecules. We study quantum gases of fermions, as well as bosons, and explore a variety of phenomena such as Bose-Einstein condensation, Cooper pairing of fermions, superfluidity, and spin models realized with ultracold polar molecules.
