摘要:

报道了在费米子s波费什巴赫共振磁场作用下,由两个自旋态$^6$ Li(费米子)和一个自旋态$^7$ Li(玻色子)组成的超流玻色-费米混合物的首次全光学产生.费米子可以通过蒸发冷却有效地冷却,它们可以作为玻色子的冷却剂。因此,超流混合物可以通过使用简单的实验装置和程序来实现,如在单一玻色-爱因斯坦凝聚体(BEC)的全光学生产的情况下。我们表明,全光学方法使我们能够实现各种超冷玻色费米混合。

英文摘要:

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.
