Ultracold RbSr Molecules Can Be Formed by Magnetoassociation
We investigate the interactions between ultracold alkali-metal atoms and closed-shell atoms using electronic structure calculations on the prototype system $\mathrm{Rb}+\mathrm{Sr}$. There are molecular bound states that can be tuned across atomic thresholds with a magnetic field and previously neglected terms in the collision Hamiltonian that can produce zero-energy Feshbach resonances …
