Dec 21, 2020 - Nature Physics article out: Dynamics of the weakly bound helium dimer

OU postdoc Qingze Guan and OU faculty member 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.
