Characterization of Feshbach resonances in using improved interaction potentials
Jing-Chen Zhang, Paul Julienne, Yu Liu
We characterize Feshbach resonances in all isotopologues of the system with improved interaction potentials. Starting from spectroscopically accurate Mo…
Isotopic effect on collisional widths and shifts of Hg clock transition induced by cold Rb atoms
Renu Bala, Adam Linek, Marcin Witkowski +7
We study the isotopic dependence of collisional widths and shifts of the Hg clock transition S-P perturbed by the Rb atoms in the temperature range from 1 nK to 1 K…
Steering reaction flux by coupling product channels
Dominik Dorer, Shinsuke Haze, Jing-Lun Li +5
We demonstrate a method for controlling the outcome of an ultracold chemical few-body reaction by redirecting a tunable fraction of reaction flux from one selected product channel…
Spin structure of diatomic van der Waals molecules of alkali atoms
Jing-Lun Li, Paul S. Julienne, Johannes Hecker Denschlag +1
We theoretically investigate the spin structure of weakly bound diatomic van der Waals molecules formed by two identical bosonic alkali atoms. Our studies were performed using know…
Spin hierarchy in van der Waals molecule formation via ultracold three-body recombination
Jing-Lun Li, Paul S. Julienne, Johannes Hecker Denschlag +1
We theoretically investigate the product-state distribution of weakly bound diatomic van der Waals molecules via ultracold three-body recombination of bosonic alkali atoms. We find…
