标题： Feshbach-resonant Raman photoassociation in a Bose-Einstein condensate

摘要： 我们通过在强Feshbach共振附近对两组分玻色-爱因斯坦凝聚体进行脉冲拉曼光缔合来模拟稳定异核分子的形成，针对反直觉和直觉脉冲序列。 与单独的激光相比，弱拉曼光缔合在反直觉（直觉）脉冲序列中可增强多达十倍（五倍），而强拉曼光缔合几乎没有任何增强——无论脉冲序列如何。 更强的原子内、分子内或原子-分子碰撞会导致转换效率的预期下降，但更强的环境原子间碰撞却意外地提高了稳定分子产生的效率。 数值结果与解析近似 reasonably 一致。 显示英文摘要

摘要： We model the formation of stable heteronuclear molecules via pulsed Raman photoassociation of a two-component Bose-Einstein condensate near a strong Feshbach resonance, for both counterintuitive and intuitive pulse sequencing. Compared to lasers alone, weak Raman photoassociation is enhanced by as much as a factor of ten (five) for a counterintuitive (intuitive) pulse sequence, whereas strong Raman photoassociation is barely enhanced at all--regardless of pulse sequence. Stronger intra-atom, molecule, or atom-molecule collisions lead to an expected decrease in conversion efficiency, but stronger ambient inter-atom collisions lead to an unexpected increase in the efficiency of stable molecule production. Numerical results agree reasonably with an analytical approximation.
