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

Postdoctoral Research Associate Job Opening

2021-01-11 :

Rice University announces an opening for a Postdoctoral Research Associate in ultracold atomic physics. The successful applicant will be a key member of an experimental program to use ultracold atomic fermions in optical lattices as a platform to realize strongly correlated many-body states of matter. The current goal is to realize a supersolid (FFLO superconductor) in the crossover region between one and three dimensions using fermionic lithium. This position offers an excellent opportunity to conduct research at the forefront of the exciting field of ultracold atomic gases.

A Ph.D. in relevant areas of experimental atomic or condensed matter physics is required. Qualified candidates are encouraged to contact Prof. R. Hulet randy@rice.edu for further information, or view http://atomcool.rice.edu.

New Paper on the p-Wave Feshbach Resonance in quasi-1D!

2020-09-30 :

We have posted a preprint entitled “Collisional loss of one-dimensional fermions near a p-wave Feshbach resonance”. This work is the first detailed experimental study of p-wave collisions in a 1D Fermi gas. We have found a possible suppression of dimer relaxation rate with strong quasi-1D confinement. We hope that these results will pave the way to observing a p-wave superfluid state. arXiv:2007.03723(2020)

New paper on Matter-Wave Breathers!

2020-09-30 :

Our paper “Creation and characterization of matter-wave breathers” has been accepted for publication in Physical Review Letters. A breather is an excited state of a soliton. Since it is a superposition of multiple fundamental solitons, its density profile oscillates periodically. We have created matter-wave breathers of two and three solitons in a 7Li Bose-Einstein condensate (BEC) by quenching the atomic interaction. This work paves ways for studying beyond-mean-field quantum effects in a BEC.
