| 摘 要： | 通过分析87Rb浓蒸汽的Zeeman效应, 将Breit-Rabi Hamilton量H=K·S+x(K+1/2)Sz推广到s=1, 并给出当x=±1时的简并态(即Zeeman效应消失). 采用Yangian代数Ysl(2)算子构造可区分这些简并态的算符, 将其作用于具有多重简并态系统可实现不同量子态间的跃迁, 从而达到解除简并态的目的.

| Abstract: | Analysis of Zeeman effect in condensed vapor of 87Rb obtained the degenerate states of the Hamiltonian H=K·S+x(K+1/2)Sz with s=1 and x=±1. The newoperator constructed of Yangian algebra (Ysl(2)), which can distinguish degenerate states, is applied to multiple degenerate system to realize the transition between different quantum states so as to eliminate degenerate states. |
