量子简并混合物的全光形成
All-Optical Formation of Quantum Degenerate Mixtures
摘要：
报道了用全光学方法实现镱（Yb）同位素量子简并混合气体的研究。我们已经成功地冷却吸引相互作用的176 Yb原子通过共振冷却到玻色-爱因斯坦转变温度以下，与174 Yb原子的稳定凝聚体共存，具有排斥相互作用。我们观察到176 Yb原子在冷却到转变温度以下后的快速原子损失，这表明176 Yb冷凝物的崩溃。应用共振冷却技术将173 Yb-174 Yb费米玻色混合物冷却到量子简并区。
英文摘要：
We report the realization of quantum degenerate mixed gases of ytterbium (Yb) isotopes using all-optical methods. We have succeeded in cooling attractively interacting 176Yb atoms via sympathetic cooling down to below the Bose-Einstein transition temperature, coexisting with a stable condensate of 174Yb atoms with a repulsive interaction. We have observed a rapid atom loss in 176Yb atoms after cooling down below the transition temperature, which indicates the collapse of a 176Yb condensate. The sympathetic cooling technique has been applied to cool a 173Yb-174Yb Fermi-Bose mixture to the quantum degenerate regime.
