The Hulet group uses ultracold lithium atoms to explore quantum many-body phenomena. Using optical lattices, we confine atomic fermions to periodic potentials or to low-dimensions where strong correlations and emergent behavior arise. The extreme tunability of lattice parameters, density, and even geometry, fulfills the requirements of a versatile analog quantum simulator …. click to continue reading

Jimmy received the Kevin Strecker Award!! 2024-05-03 : Jimmy Yeh received the Kevin Strecker Award in recognition of his excellent performance on the qualifying exam and research proposal. Well done, Jimmy!
Eva has defended her PhD thesis! 2024-01-05 : Congratulations to Eva, who has successfully defended her PhD thesis entitled “Decoherence of Matter-Wave Breathers in Lithium Bose Einstein-Condensates”. We wish Eva continued success upon her future career at Booz Allen Hamilton!
Welcome Ellie, Mike and Sara! 2023-06-29 : We welcome Ellie, Mike, and Sarah to our group during the summer. Ellie is a senior student from Middlebury College, Vermont. She is working on the circuit and low-noise power supply for the p-wave superfluid experiment. Mike is a Rice undergraduate student. He is building an AOM driver to be used for UV MOT narrow linewidth cooling of Lithium 6. Sarah is a senior student at the University of Sao Paolo, Brazil. She studies the granulation of a BEC by modulating the scattering length using a Feshbach resonance. Welcome to Hulet Lab!!
