Abstract:
We report the realization of a quantum degenerate mixture of bosonic 87Rb and fermionic 171Yb atoms in a hybrid optical dipole trap with a tunable, species-dependent trapping potential. 87Rb is shown to be a viable refrigerant for the noninteracting 171Yb atoms, cooling up to 2.4 × 105 Yb atoms to a temperature of T/T F = 0.16(2) while simultaneously forming a 87Rb Bose-Einstein condensate of 3.5 × 105 atoms. Furthermore we demonstrate our ability to independently tailor the potentials for each species, which paves the way for studying impurities immersed in a Bose gas.
