标题： Efimov states in Li-Cs mixtures within a minimal model

摘要： 我们使用一个最小的零范围模型来描述由两个铯原子和一个锂原子组成的三体束缚态谱。 使用一个宽泛的费什巴赫共振模型来描述两体相互作用，我们表明，最近来自Chin小组的实验数据可以被非常准确地描述，对于控制原子势短程行为的三体参数的特定值，这些参数超出了零范围模型的范围。 研究谱作为三体参数的函数表明，实验中观察到的最低状态可能受到有限范围修正的影响。 我们还考虑了费米简并度以及对应的锂原子对Efimov态的泡利阻塞问题。 显示英文摘要

摘要： We use a minimal zero-range model for describing the bound state spectrum of three-body states consisting of two Cesium and one Lithium atom. Using a broad Feshbach resonance model for the two-body interactions, we show that recent experimental data from the Chin group can be described surprisingly well for particular values of the three-body parameter that governs the short-range behavior of the atomic potentials and is outside the scope of the zero-range model. Studying the spectrum as a function of the three-body parameter suggests that the lowest state seen in experiment could be influenced by finite range corrections. We also consider the question of Fermi degeneracy and corresponding Pauli blocking of the Lithium atoms on the Efimov states.
