中文摘要 | 研究了存在原子间有效三体相互作用的情况下双阱势场中超冷玻色气体的相位相干性,其中引入无序分布的阱深差来模拟无序势。研究发现,在无序Bose-Hubbard模型中,重整化的三体相互作用能有效增强玻色气体的相位相干性。同时,在强无序势条件下,讨论了平均相位相干性对三体相互作用的依赖关系。据我们所知,这是首次对无序量子气体中的有效三体相互作用进行研究。 |
英文摘要 | We investigate the phase coherence of bosons in a double-well trap with a random energy mismatch that is used to mimic disorder in the presence of effective three-body interaction. It is found that, in such a double-well disordered Bose-Hubbard model, the renormalized three-body interaction can enhance the phase coherence of the bosonic system in the presence of disorder. The dependence of the average phase coherence on the effective three-body interaction in the situation of strong disorder is also studied. To our best knowledge, it is the first time that the effective three-body interaction is investigated in the context of disordered quantum gases. |
