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.</p> <p>A Ph.D. in relevant areas of experimental atomic or condensed matter physics is required.

We thank Jake, and wish for continued sucess!</p> 2022-04-24T00:00:00-05:00 /uvsc / <img src="/images//SC_main.png"><br/> <p>Our paper “Spin-charge separation in a 1D Fermi gas with tunable interactions” has been accepted for publication in <i>Science</i>. The spatial separation of spin and charge excitations has been a hallmark of the Tomonaga-Luttinger liquid (TLL) theory for over 70 years. We are able to independently excite either the charge or the spin mode in our quasi-1D system using Bragg spectroscopy. Our work is the first to directly observe spin-charge separation as a function of interactions. The separate charge and spin sectors are clearly demonstrated by the data. We also observe non-linear effects, paving the way for further exploration of non-linear Luttinger liquids. Congratulations to our team here at Rice and our collaborators at the Chinese Academy of Sciences and SISSA (Italy). <a href="https://www.science.org/doi/10.1126/science.abn1719">Science, 376, 6599 (2022)</a></p> 2021-05-10T00:00:00-05:00 /ya-ting_phd / <p>Congratulations to Ya-Ting, who has successfully defended her PhD thesis entitled “Collisional loss of one-dimensional fermions near a p-wave Feshbach resonance”.

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.</p> 2020-09-29T00:00:00-05:00 /pwave2020 / <img src="/images//pwave2020.png"><br/> <p>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. <a href="https://arxiv.org/abs/2007.03723">arXiv:2007.03723(2020)</a></p> 2020-09-28T00:00:00-05:00 /lab_video / <p>Watch our student-made video on what it’s like to work here as a new student!</p> <iframe width="560" height="315" src="https://www.youtube.com/embed/RP_RCOj7lhU" frameborder="0" allowfullscreen=""></iframe> 2020-01-27T00:00:00-06:00 /revsci2020 / <img src="/images//revsci2020.jpg"><br/> <p>A review article of the methods developed for cooling and trapping lithium has appeared in the Reviews of Scientific Instruments.
