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…
Magnetic Feshbach resonances in Ba+Li collisions due to strong spin-orbit coupling
Masato Morita, Joachim Siemund, Wei Wu +8
We report a pronounced dependence of magnetic Feshbach resonance spectra on the initial hyperfine-Zeeman state of Li in ultracold Ba+Li collisions. The measured num…
What is the diatomic molecule with the largest dipole moment?
Ahmed Elhalawani, Ruiren Shi, Mateo Londoño Castellanos +2
We present a machine learning model for predicting the electric dipole moment of diatomic molecules using only the atomic properties of the constituent atoms. Our model can screen…
Quantum control of ion-atom collisions beyond the ultracold regime
Maks Z. Walewski, Matthew D. Frye, Or Katz +3
Tunable scattering resonances are crucial for controlling atomic and molecular systems. However, their use has so far been limited to ultracold temperatures. These conditions remai…
Ultralong-range Rydberg molecules of Hg atoms
Agata Wojciechowska, MichaÅ Tomza, Matthew T. Eiles
Ultralong-range Rydberg molecules, composed of an excited Rydberg atom and a ground-state atom, are characterized by large bond lengths, dipole moments, sensitivity to external fie…
