Nature Physics article out: Dynamics of the weakly bound helium dimer

OU postdoc Qingze Guan and Blume collaborated with Maksim Kunitski, Reinhard Doerner and others from Frankfurt University and the GSI in Darmstadt on the helium dimer. The helium dimer is one of the most weakly-bound “naturally” occurring molecules. Since it’s so weakly bound, the preparation and manipulation of this fascinating molecule are rather tricky. Unless you isolate the dimer and are extremely careful, it tends to fall apart… Maksim and coworkers set up an ingeneous molecular beam experiment and used femto-second lasers to probe the system. The theory calculations by Qingze do not only match the experimental data, without a single adjustable parameter, but additionally provide unique insights. Check out the article entitled “Ultrafast manipulation of the weakly bound helium dimer”, which just appeared in Nature Physics, and the accompanying “News & Views” highlight entitled “Gently stirred not shaken” by Daniel Rolles.

Marino receives DOE grant for quantum enhanced fiber sensing

An interdisciplinary collaborative effort led by Alberto Marino involving Louisiana State University and Oak Ridge National Laboratory was funded by DOE. The initiative will leverage recent developments in quantum information science in sensing. The project will aim at improving current commercial techniques for leakage detection in the oil and gas industry by using quantum states of light to enhance the sensitivity of fiber optic sensors beyond the classical limit. The goal is to outperform the sensitivity of available state-of -the art techiques by one or two orders of magnitude. More information 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:

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.
