We report on the first realization of a dual-species magneto-optical trap that combines strongly magnetic lanthanide atoms (Dy) with an alkali species (K). Advanced cooling techniques in the form of narrow-line laser cooling and grey-molasses cooling give us favorable starting conditions to reach quantum degeneracy. With fermionic and bosonic isotopes of both species, our system offers a great wealth of isotopic mixtures. We are particularly interested in new Fermi-Fermi mixtures. These are expected to exhibit exotic quantum phases and novel pairing mechanisms, including for example mass-imbalanced pairing or a fermionic superfluid with a Fermi surface modified by the dipolar interactions.
