Description
In contrast to the more common alkali atoms, Ytterbium features a
strong decoupling between the nuclear and the electronic spin degree
of freedom and possesses a metastable excited state. In consequence,
interactions cannot be enhanced with standard magnetic
Feshbach resonances as in alkalis. We report on the discovery of a
new orbital interaction-induced Feshbach resonance in Ytterbium-173.
In a second experiment, we investigated the SU(N)-symmetric Fermi-
Hubbard model, realized by loading Ytterbium-173 atoms into a threedimensional
optical lattice. We prepared a low-temperature SU(N)-
symmetric Mott insulator and characterized the Mott crossover by
probing it locally, representing important steps towards probing predicted
novel SU(N)-magnetic phases.
