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!

Sept. 16, 2021: Thank you, thank you, and another thank you to the Dodge Family!!!

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!

September 2021: Bisons in the Wichita Mountains

Ok, this is not physics—but it’s pretty cool: Doerte ran into a herd of about 70 bisons while hiking the bison trail in the Wichita Mountains over Labor Day weekend. How often do you get to experience this? No fences or barriers — one of the most amazing sights! Apparently the name of the trail is not random… According to the Wildlife Refuge’s website, there are an estimated 350 bisons in the area. 70 out of 350 — that’s 20%…. Medicine Park, which is situated just outside of the Refuge, is an easy 75-minute drive from Norman.

Congratulations to Kevin Mack-Fisher

Kevin passed his last qualifier. Congratulations, Kevin! With class work and qualifiers out of the way, we are looking forward to many interesting research discussions.

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.

January 2021: Wishing postdoc Jianwen Jie all the best for the future!

Farewell to Jianwen…

Safe travels!

And all the best for your and your family’s future adventures!

Hiking the Ouachita National Recreation Trail: Oklahoma/Arkansas Border

January 2021: Welcome to undergraduate Aidan Sudler

Welcome to Aidan Sudler! Aidan, a Freshman at OU, has joined the group to get involved in research. Aidan is part of OU’s FYRE program and will be exploring the classical dynamics of non-trivial harmonic oscillators, such as the van der Pol oscillator. The goal will be, down the road, to explore connections to quantum statistical mechanics descriptions.

Some press on Nature Physics article

The article entitled “Ultrafast manipulation of the weakly bound helium dimer” by Kunitski, Guan, et al., which appeared in Nature Physics on December 21, 2020, and is accompanied by a “News & Views” highlight entitled “Gently stirred not shaken” by Daniel Rolles, received quite a bit of press. See, for example “Quantum wave in helium dimer filmed for the first time: Collaboration between Goethe University and the University of Oklahoma” for a nice highlight by nanotech-now. Nature Physics had listed 14 news stories from 11 outlets on January 8, 2021.

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.
