Realization of a quantum degenerate mixture of highly magnetic and nonmagnetic atoms

Abstract

We report on the experimental realization of a bosonic quantum degenerate mixture of highly-magnetic 168Er and nonmagnetic 174Yb. Quantum degeneracy is reached by forced evaporation in an all-optical trap. Formation of the two Bose-Einstein condensates is confirmed by analysis of the cloud shape and the observed inversions of the aspect ratios. The results open a path for possible new experiments on magnetic and nonmagnetic impurity physics as well as on the quantum chaotic behavior of Feshbach resonances and their dependencies on minor variations of the reduced masses.
