约化的qKZ方程:一般情况

Reduced qKZ equation: general case

A. Klümper, Kh. S. Nirov, A. V. Razumov

摘要:

我们用量子群方法研究了可积顶点模型和自旋链的关联函数。对于任意单李代数的非齐次约化密度矩阵,我们找到了约化量子Knizhnik-Zamolodchikov方程形式的泛函方程。该方程是研究任意温度下的关联函数的出发点,特别是对于基态。

英文摘要:

We use the quantum group approach for the investigation of correlation functions of integrable vertex models and spin chains. For the inhomogeneous reduced density matrix in case of an arbitrary simple Lie algebra we find functional equations of the form of the reduced quantum Knizhnik-Zamolodchikov equation. This equation is the starting point for the investigation of correlation functions at arbitrary temperature and notably for the ground state.
