Realization of a Strongly Interacting Fermi Gas of Dipolar Atoms

We report on the realization of a strongly interacting Fermi gas with a dipolar spin mixture of fermionic erbium. Employing a lattice-protection technique, we prepare deeply degenerate Fermi mixtures of the two lowest spin states and perform high-resolution Feshbach spectroscopy. We identify a comparatively broad Feshbach resonance and precisely map the inter-spin scattering length across the resonance. We show a remarkable collisional stability of the quantum mixture in the strongly interacting regime, providing a first step towards BEC-to-BCS studies in presence of dipole-dipole interaction.
