We have recently developed a home-made and unexpensive high power laser source @425nm: up to 800mW of blue light for laser cooling of Chromium! |
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.
