【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)S z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.更多还原

【Abstract】 Analysis of Zeeman effect in condensed vapor of87Rb obtained the degenerate states of the Hamiltonian H = K·S+x(K+1 /2) S z with s = 1 and x = ±1.The new operator 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.更多还原
