A key step in creating controlled interactions in dipolar quantum mixtures is the characterization of interspecies Feshbach resonances.
In this work, we identify and characterize several relatively broad resonances between erbium and dysprosium atoms, as well as an abundance of narrow resonances. These resonances will provide a crucial tool for tuning the interspecies scattering length in erbium-dysprosium mixtures, enabling future studies on miscibility, vortices, and supersolidity in dipolar mixtures.
