The Hulet group investigates atoms at temperatures as low as a few nano-Kelvin. At such low temperatures, the strange and fascinating effects of quantum mechanics dominate, greatly altering normal atomic behavior. Hulet and his group have used laser cooling and atom trapping techniques to explore this exotic regime of matter, investigating ultracold atom collisions, Bose-Einstein condensation, and pairing of atomic Fermi gases. Our current interest is the realization of fundamental models of condensed matter using ultracold atoms confined by optical lattices, the study of few-body physics of bosons with resonant interactions, and realizations of matter-wave solitons.

New paper on the formation of soliton trains!

2017-04-28 :

Jason, Henry, and Randy's manuscript on the formation of soliton trains by quenching the interactions of a repulsively interacting BEC to an attractive one has been published! This work provides new insight on how and why neighboring solitions repel one another.

Best Wishes to Melissa!

2016-11-30 :

It’s been a big month for Melissa - She started a post-doc at the Sandia National Laboratories, where she will be working on quantum information. Her paper on the dimensional crossover in spin-polarized Fermi gases has just been accepted and published in the Physical Review Letters.

We wish Melissa continued success!

Randy has received the Walther Award!

2016-11-17 :

Randy has been awarded the 2017 Herbert Walther Award.

The citation reads: “For pioneering achievements in the field of ultracold atomic gases, including the achievement of Bose-Einstein condensation with attractive interactions and groundbreaking studies of atomic fermions.”

Melissa has defended her PhD thesis!

2016-09-14 :

Melissa Revelle has defended and submitted her thesis entitled “Quasi-One-Dimensional Ultracold Fermi Gases.” In addition, her paper entitled “1D to 3D Crossover of a Spin-Imbalanced Fermi Gas”, has now been submitted for review: https://arxiv.org/abs/1605.06986.

New Paper!

2016-09-02 :

A new paper describing the results of a theoretical collaboration with Vincent Liu’s group at the University of Pittsburgh was published today. This paper shows that a p-wave superfluid can be created using an s-wave Feshbach resonance and imbalanced Fermi surfaces. We hope that this may be a viable route to producing a topological superfluid. Physical Review A 94, 031602 (2016). PDF
