摘要
XYZ海森堡反铁磁模型的哈密顿量在自旋波近似下具有su(1,2)李代数结构,利用代数对角化方法,通过相似变换得到该模型的能量本征值,为理论分析该模型在物理中的性质和代数对角化方法的应用提供了更广泛的依据.
Under the linear spin - wave frame, the XYZ antiferromagnetic model is proposed to have su(1,2) algebraic structure. By making use of the algebraic diagonalization method, the energy eigenvalue solutions are obtained through the similar transformation. These offer more foundations for the theoretical analysis of this model in physics and for the applications of algebraic diagonalization method in physical models.
