Universality in Ionic Three-body Systems Near an Ion-atom Feshbach Resonance
Jacek Gȩbala, MichaŠTomza, José P. D'Incao
We calculate bound and scattering properties of a system of two neutral atoms and an ion near an atom-ion Feshbach resonance. Our results indicate that long-range atom-ion interact…
Lellouch-Lüscher relation for ultracold few-atom systems under confinement
Jing-Lun Li, Paul S. Julienne, Johannes Hecker Denschlag +1
We derive an analog of the Lellouch-Lüscher (LL) relation for few-body bosonic systems, linking few-body scattering loss rates to the energies and widths of the corresponding harm…
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…
Controlling few-body reaction pathways using a Feshbach resonance
Shinsuke Haze, Jinglun Li, Dominik Dorer +5
Gaining control over chemical reactions on the quantum level is a central goal of the modern field of cold and ultracold chemistry. Here, we demonstrate a novel method to coherentl…
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…
