Quantum Degenerate Mixtures of Alkali and Alkaline-Earth-Like Atoms
Quantum Degenerate Mixtures of Alkali and Alkaline-Earth-Like Atoms
We realize simultaneous quantum degeneracy in mixtures consisting of the alkali and alkaline-earth-like atoms Li and Yb. This is accomplished within an optical trap by sympathetic cooling of the fermionic isotope $^{6}\mathrm{Li}$ with evaporatively cooled bosonic $^{174}\mathrm{Yb}$ and, separately, fermionic $^{173}\mathrm{Yb}$. Using cross-thermalization studies, we also measure the elastic $s$-wave …
