Efimov三聚体的超冷四体凝聚

Efimov Trimer Formation via Ultracold Four-body Recombination

Yujun Wang, B. D. Esry

摘要:

我们讨论了Efimov三聚体通过超冷四体复合的碰撞形成。特别地,我们考虑了A+A+A+B-> A ~ 3 +B与A和B超冷原子的反应。我们得到的四体复合率的表达式,并表明,它反映了三体Efimov物理无论是作为碰撞能量的函数,或作为一个函数的两体s-波散射A原子之间的长度。此外,我们简要地讨论了重要的实验观察这个有趣的和相对未开发的过程的问题。

英文摘要:

We discuss the collisional formation of Efimov trimers via ultracold four-body recombination. In particular, we consider the reaction A+A+A+B->A3+B with A and B ultracold atoms. We obtain expressions for the four-body recombination rate and show that it reflects the three-body Efimov physics either as a function of collision energy or as a function of the two-body s-wave scattering length between A atoms. In addition, we briefly discuss issues important for experimentally observing this interesting and relatively unexplored process.
