摘要
利用Y(SL( 2 ) )的自旋 -1 /2实现 ,给出在外磁场情况下两自旋耦合系统的Berry拓扑相因子态之间与核磁共振态之间新的平移算子 ,它们超出原有李代数的范围 ,描述了在任意时刻量子态之间新的跃迁 .
According to the spin-1/2 realization of Y(SL(2)) algebra,this paper can give the new shift operators among the states of Berry topological phase ,and also give the new ones among the states of nuclear magnetic resonance when the two spin interactive system is put into an extra magnetic field.These new shift operators have already beyond the material of Lie algebra,and they give new shift relations between two quantum states at any time.
