All-optical production of a superfluid Bose-Fermi mixture of ${}^6$Li and ${}^7$Li

Abstract

We report the first all-optical production of a superfluid Bose-Fermi mixture with two spin states of ${}^6$Li (fermion) and one spin state of ${}^7$Li (boson) under the resonant magnetic field of the s-wave Feshbach resonance of the fermions. Fermions are cooled efficiently by evaporative cooling and they serve as coolant for bosons. As a result, a superfluid mixture can be achieved by using a simple experimental apparatus and procedures, as in the case of the all-optical production of a single Bose-Einstein condensate (BEC). We show that the all-optical method enables us to realize variety of ultracold Bose-Fermi mixtures.
