旋量三体问题中Efimov态族的出现
On the Appearance of Families of Efimov States in the Spinor Three-Body Problem
摘要：
能够进入多个内部层次的少体系统表现出的丰富性超出了通常在单层次系统中发现的丰富性。一个例子是强关联旋量三体系统中的Efimov态。在[V. E.科卢西角H. Greene和J.P. D'Incao，Phys. Rev. Lett. { \bf 113}，045302（2014）]针对旋量凝聚物分析该问题，发现如在早期工作中的复杂能级结构[Bulgac和Efimov，Sov. J.Nucl.Phys.22，153（1976）]中的方法，并计算了Efimov物理对散射观测量的一般形式的影响。本文讨论了旋量三体问题中出现的新的Efimov态族。
英文摘要：
Few-body systems with access to multiple internal levels exhibit richness beyond that typically found in their single-level counterparts. One example is that of Efimov states in strongly-correlated spinor three-body systems. In [V. E. Colussi, C. H. Greene, and J. P. D'Incao, Phys. Rev. Lett. {\bf 113}, 045302 (2014)] this problem was analyzed for spinor condensates finding a complex level structure as in an early work [Bulgac and Efimov, Sov. J. Nucl. Phys. 22, 153 (1976)] in nuclear physics, and the impact of Efimov physics on the general form of the scattering observables was worked out. In this paper we discuss the appearance of novel families of Efimov states in the spinor three-body problem.
