三体系统中的Efimov态(英文)

Efimov States in Three body Systems

摘要: 通过求解Faddeev方程，研究了量子三体系统中的Efimov效应。改进了变分方法对于求解激发态的不足。在不同的两体作用下得到了三体系统中的Efimov态。讨论了在不同质量比的三体系统中出现Efimov态的条件。并由三体计算的结果分析了具有两个价中子的核系统在两体存在束缚态时可能存在的Efimov效应。We studied the Efimov effect in a threebody system by solving the Faddeev equations. Different models and interactions were considered. The occurrence of Efimov states was discussed. The possible Efimov state was clearly presented and its properties were investigated.
