Energy transfer collisions between two laser excited alkali atoms of different species have been investigated in cell experiments using an intermodulation technique. Cross sections have been measured for the potassium/rubidium mixture and evidence of three‐body collisions in presence of a buffer gas has been obtained in the sodium/potassium mixture.

We have created a triply quantum-degenerate mixture of bosonic $^{41}\mathrm{K}$ and two fermionic species $^{40}\mathrm{K}$ and $^{6}\mathrm{Li}$ . The boson is shown to be an efficient coolant for the two fermions, spurring hopes for the observation of fermionic superfluids with imbalanced masses. We observe multiple heteronuclear Feshbach resonances, in particular a wide $s$ -wave resonance for the combination $^{41}\mathrm{K}$ - $^{40}\mathrm{K}$ , opening up studies of strongly interacting isotopic Bose-Fermi mixtures. For large imbalance in the local densities of different species, we enter the polaronic regime of dressed impurities immersed in a bosonic or fermionic bath.We have created a triply quantum-degenerate mixture of bosonic $^{41}\mathrm{K}$ and two fermionic species $^{40}\mathrm{K}$ and $^{6}\mathrm{Li}$.
