Jun 19, 2020 - 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.
