摘要通过广义暗态方法形成稳定分子凝聚物^(41)K_2^(87)Rb_2,即Efimov-共振辅助条件下的激发绝热通道,在此过程中,双通道随量子化学反应间的相长干涉可以进一步提高分子制备的产率.进一步研究表明,初始粒子数的布居不平衡也会对该条件下的原子-分子转化率产生重要影响. We study the generalized dark-state scheme for creating stable molecules 41 K2 87 Rb2 from the atomic mixture condensates by resorting to a Efimov-resonance assisted stimulated adiabatic passage. It shows that the conversion rate can be further enhanced via the constructive interference between two different quantum chemical reaction channels. In addition, the important effect of the initial population imbalance on the dark state atom-molecule conversion is investigated.
