Center for Quantum Research and Technology (CQRT)
Postdoctoral position in theoretical condensed matter physics
The Center for Quantum Research and Technology (CQRT) at the University of Oklahoma invites applications for one postdoctoral scholar position in Theoretical Condensed Matter physics, starting in the summer or fall of 2021. The successful candidate will work primarily in the group of Prof. Bruno Uchoa, and will interact with other members of the CQRT in the areas of Condensed Matter and Atomic, Molecular and Optical physics. Primary areas of interest include but are not limited to twisted graphene bilayers, topological phases of matter, and strongly correlated quantum systems.
The position is expected to last for two years, with a possible extension for a third year upon availability of funds. Candidates should send a CV (pdf file) containing a list of publications, a description of main research achievements and arrange for three reference letters to be sent to email@example.com. Applications received by December 31, 2020will receive full consideration. The position will remain open until filled.
Announcing: Prospective Graduate Student (Virtual) Open House
The Department of Physics and Astronomy is hosting a prospective graduate student virtual open house on Tuesday, November 17, and Thursday, December 3. We will have representatives from the admission committee, our Women in Physics group, our Lunar Sooners group, and our physics graduate student association in attendance. More information about the open house can be found here.

OU-WSU paper highlighted in Physical Review A
A joint theory-experiment paper by the Blume group from OU and the Engels group from Washington State University (WSU) was selected as an Editors' Suggestion by Physical Review A. The theory efforts were spearheaded by OU postdoc Dr. Qingze Guan and the experimental data were taken by Thomas Bersano and Dr. Sean Mossman, both from WSU. The work explores two realizations of a two-state model in a rubidium Bose-Einstein condensate, realized through Raman coupling of hyperfine states and lattice coupling in momentum space. The difference in the two realizations is highlighted by a particularly important role of interactions in the lattice coupling case. The work can be accessed at the APS website: https://journals.aps.org/pra/abstract/10.1103/PhysRevA.101.063620.

Presidential Dream Course on Quantum Hybrid Systems
A second quantum technology revolution is upon us! The first used the laws of quantum physics to design systems in which the energy is “quantized,” to allow only certain values. This idea is at the heart of technology ranging from TV remotes to supercomputers. Now, two other features of quantum mechanics, entanglement and superposition, are becoming accessible to control. To do so we must unite the incredible delicacy and uniformity of single atoms with the robust control and reproducibility of larger devices, forming “quantum hybrid systems.”
This Presidential Dream course will give students competence in the fundamentals so that they may pursue research and careers in this field. As part of the course world experts will come to OU to give lectures and meet with students.
