量子超化学中的类双缝干涉:玻色-爱因斯坦凝聚原子-三聚物相干转化

Coherent atom-trimer conversion in a repulsive Bose-Einstein condensate

文章作者首次研究了玻色凝聚体中原子与三原子异核分子间的相干转化过程,特别是双通道量子干涉效应的作用,该效应可以看作是量子简并物质波化学中的类双缝干涉.利用相长干涉可以进一步提高分子制备过程的产率,为异核分子的产生和相干调控提供了一个新的技术.此工作发表在2007年第9卷第133002页的Phys.Rev.Lett上.

In our recent work（H. Jing, J. Cheng, and P. Meystre, Phys. Rev. Lett. 99, 133002 （2007））, we studied the constructive interference between two chemical reaction channels in the process of coherent atomtrimer conversion in a repulsive atomic Bose condensate. This interference can be viewed as a double-slit-like interference in quantum degenerate matter-wave chemistry （superchemistry）. The constructive interference can lead to a significant enhancement of trimer production, leading to a new technique for coherent assembly and control of ultracold heteronuclear molecules.
