1/16/23: Beyond the SMA work up on arXiv
Work led by Jianwen Jie on the theory side and Shan Zhong on the experimental side is out on the arXiv. The manuscript is entitled “Dynamical mean-field driven spinor condensate physics beyond the single-mode approximation.” Congratulations to theorists and experimentalists alike. It’s really nice to see the agreement between the experimental data from Arne Schwettmann’s lab and the Gross-Pitaevskii theory.
1/6/23: Spinor BEC work out on arXiv
Zach Hardest-Shaw, graduate student in the OSU group led by Yingmei Liu, uploaded our sodium spinor BEC manuscript to the arXiv. The manuscript is entitled “Manipulation of nonequilibrium spin dynamics of an ultracold gas in a moving optical lattice.” Take a look at the beautiful experimental data, taken by Zach and Jared Austin (great job Zach and Jared!). The dynamic single-mode approximation theory, developed by Qingze Guan and Robert Lewis-Swan very convincingly describes the experimental data. Congratulations to all!
Welcome to postdoc Balakrishnan Viswanathan! We are looking forward to working together.

September 16, 2021 is a memorable day for the Homer L. Dodge Department of Physics and Astronomy — we are extremely grateful to the Dodge family for their generous gift. OU’s announcement states: “The Dodge family chose to reserve half of the historic gift for OU’s Homer L. Dodge Department of Physics and Astronomy, within the College of Arts and Sciences, of which Homer Dodge was a former professor and chair. The physics department was renamed the Homer L. Dodge Department of Physics and Astronomy in 2005. Of the funds earmarked for the Physics and Astronomy Department, the majority will benefit the Dodge Family Postdoctoral Research Fellows Fund, followed by the Research Faculty Fund, the Strategic Research Investment Fund, and the Dean’s Student Recruitment and Bridge Fund. The remainder of the Physics and Astronomy Department allocation will go to the Distinguished Visitor and Workshop Fund and the Dean’s Graduate and Postdoctoral Retention Fund.” What a monumental and transformational moment for the department!

February 2021: Doerte named Outstanding Referee
The highly selective Outstanding Referee program annually recognizes about 150 of the roughly 71,000 currently active referees. At the start of the program, in 2008 and 2009, larger groups were selected by our Editors for the Outstanding Referee designation, in order to “catch up” and recognize referees who had already served for many years. Like Fellowship in the APS, this is a lifetime award. In this year, 2021, 151 Outstanding Referees were selected — Doerte was among them. Check out the APS announcement. Thanks to Physical Review and their staff for their excellent work, ensuring and promoting quality peer-review.
Congratulations to graduate student Dave Hill
Dave passed his last two qualifiers. Congratulations, Dave! With class work almost done, we are looking forward to great research contributions.

Call for Nominations for 2021 Faddeev Medal
We are pleased to announce the call for nominations for the 2021 “Faddeev Medal”
Prize. We are seeking nominations of scientists who have advanced the field of
few-body physics significantly, either through ground-breaking research or due to
crucial progress achieved over the course of their career.
The Faddeev medal was inaugurated in 2016 by the Topical Group on Few-Body Systems & Multiparticle Dynamics (GFB) of the American Physical Society and the European Research Committee on Few-Body Problems in Physics (ERCFBP) to recognize distinguished achievements in few-body physics. It is named in honor of distinguished scientist Ludwig D. Faddeev (1934-2017). It was awarded for the first time in 2018 to Vitaly Efimov and Rudi Grimm for “the theoretical discovery of a series of weakly-bound three-body quantum states known as Efimov states” and “in recognition of his ground-breaking experiments confirming the Efimov effect”, respectively.
The nomination deadline for the 2021 “Faddeev Medal” is April 15, 2021. See this link for more details.
