当两个包含单个原子的光学阱合并时,两个超冷原子结合形成弱结合分子就会发生。分子形成发生在分子状态和原子对最低运动状态之间的避免交叉处。我们发展了非同构非球形圈闭对的合并关联理论。我们开发了一种耦合通道方法来研究两个原子的相对运动,并给出了对圆柱形对称阱作为其各向异性函数的结果。我们关注的是避免交叉的强度。我们还开发了一种近似方法,可以深入了解交叉强度对纵横比的依赖性。
Mergoassociation of two ultracold atoms to form a weakly bound molecule can occur when two optical traps that each contain a single atom are merged. Molecule formation occurs at an avoided crossing between a molecular state and the lowest motional state of the atom pair. We develop the theory of mergoassociation for pairs of nonidentical nonspherical traps. We develop a coupled-channel approach for the relative motion of the two atoms and present results for pairs of cylindrically symmetrical traps as a function of their anisotropy. We focus on the strength of the avoided crossing responsible for mergoassociation. We also develop an approximate method that gives insight into the dependence of the crossing strength on aspect ratio.
