论文摘要
我们研究了热力学极限中可集成$ O（N）$自旋链的相关函数。我们解决了解决与$ o（n）$旋转链有关的密度矩阵的量子knizhnik zamolodchikov类型的函数方程的问题。我们为$ o（n）$的两个点密度矩阵元素提供明确的解决方案，然后对$ n = 3,4，\ dots进行评估，在零温度下8 $ cases。
We study the correlation functions of the integrable $O(n)$ spin chain in the thermodynamic limit. We addressed the problem of solving functional equations of the quantum Knizhnik Zamolodchikov type for density matrix related to the $O(n)$ spin chain. We give the explicit solution for two-sites density matrix elements for the $O(n)$ which are then evaluated for the $n=3,4,\dots,8$ cases at zero temperature.
