Mass imbalanced fermions are great! In the CrLi lab we produce novel ultracold mixtures composed by Lithium and Chromium fermionic atoms. At the Cr-Li mass ratio exotic trimer states exist, which in turn will allow the first resonant control of elastic three-body interactions. This opens new perspectives for the study of elusive superfluid and magnetic phases with ultracold fermions.

Chromium and lithium fermions get cold together

We brought into the cold regime the first chromium-lithium fermionic mixture worldwide. within a 5 sec. duty cycle, we produce samples of about 4 million chromium and 300 million lithium atoms at a few hundreds of microKelvin. Our work just got published in Phys. Rev. A.
