Our main goal is to create novel types of superfluids in a mixture of two fermionic species. According to theoretical predictions, exotic regimes of superfluidity are strongly favored if mass imbalance of the constituents is present. We have identified a mixture of Dy-161 and K-40 as a very promising candidate and we have set up a new two-species apparatus. Experiments on evaporative cooling and on the search for Feshbach resonances are in progress.
