We devised a simple, totally passive scheme that enables to realize an inexpensive optical trapping apparatus free from thermal lensing effects. Our work just got published in Optics Express. C. Simonelli et al., |
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.
