Lattice confined mixtures and molecules of Yb and Li: Feshbach resonances and interaction-driven dynamical delocalization

We will report on experiments on ultracold ytterbium and lithium atoms in lattice confinement. After having observed multiple interspecies magnetic Feshbach resonances between the open-shell Li and the closed-shell Yb ground state atoms [1], we are working to apply these resonances towards the magnetoassociation of ultracold YbLi molecules in the electronic ground state. Magnetoassociation efficiency can be enhanced in an optical lattice geometry to provide high spatial overlap between the species. We will report on our successful implementation of a three-dimensional optical lattice at the optical wavelength of 1073nm for the two-species mixture. Using two arms of the lattice to create 1D traps, and the third as a pulsed-standing-wave source, we have also realized a quantum kicked rotor in 1D. We will additionally report on our observation of interaction-driven dynamical delocalization using Yb bosons in this system.
