Strongly interacting ultracold quantum gases of fermionic Ytterbium-173 — •Luis Riegger1,2, Diogo Rio Fernandes1,2, Moritz Höfer1,2, Christian Hofrichter1,2, Francesco Scazza1,2, Immanuel Bloch1,2, and Simon Fölling1,21Ludwig-Maximilians-Universität, Schellingstraße 4, 80799 München, Germany — 2Max-Planck-Institut für Quantenoptik, Hans-Kopfermann-Straße 1, 85748 Garching, Germany

Degenerate ensembles of ytterbium and alkaline-earth atoms allow novel many-body systems to be implemented due to their extended SU(N)-symmetry and the existence of a metastable internal “clock” state, introducing a yet unexplored orbital degree of freedom. Motivated by the possibility of simulating two-orbitals physics with cold atoms, we investigate the coupling of the clock state to external degrees of freedom via state-dependent potentials. In addition we characterize strongly interacting SU(N)-symmetric Fermi gases of 173Yb in the 3D lattice by probing the equation of state in the trap.
