Anderson模型中的自旋极化效应是一个普遍存在的问题.本文从Anderson杂质模型出发,利用变分及对角化方法分析了自旋极化所引起的系统基态性质的改变,分别研究了自旋极化对Kondo单态以及高温超导两分量模型中Zhang-Rice单态稳定性的影响问题.

The effect of spin polarization on the ground state of Kondo type system is a fundamental issue in study of Anderson model. By using variational and diagonal methods we analysis the stability of Kondo singlet state in s-d model and Zhang-Rice singlet state in two-component model for high Tc superconductivity when Cu site spin polarization is considered.-
