摘要
通过对由哈密顿量H0=-g L1.L2+λL32描述的量子模型引入Yangian算子,使原来处在简并的状态产生分裂,并求出此时本征值的变化.同时计算了特定值下的几个例子,从例子中可找出Yangian算子在量子可积系统中的作用.结果表明,Yangian可以以一种特定的方式将不同权之间的态联系起来,推广了量子力学中跃迁算子.
It is broken up the degenerate stats and worked out the change of the corespondent eigenvalue by introducing Yangian operator for the quantum model described by H0=-g^→·L^→2＋λL2^3 Meanwhile, it is given that the function of Yangian in the quantum integrable model and shown that Yangian plays a role of shift operator between the different weights.
