We have studied their scattering properties and identified a comparatively broad interspin Feshbach resonance in the vicinity of which we can tune the interspin interaction from strongly attractive to strongly repulsive. The Fermi mixture shows a remarkable collisional stability in the strongly interacting regime, providing a first step towards studies of superfluid pairing in the celebrated BEC-BCS crossover, adding the exceptional few-body scattering scenario brought by magnetic Lanthanide atoms.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>In our Erbium experiment, we have created the first two component dipolar Fermi gas with tunable interactions.
