XXZ链的关联振幅(英文)

Correlation Amplitude of The XXZ Chain

针对XXZ链，利用解析方法，导出了一个长距离关联函数振幅的解析表达式,结果和他人的数值计算结果一致．

For the XXZ chain, using the analytical method, we proposed an analytical expression for the amplitude defining the long distance asymptotic of the correlation function <>. The result is comparable with others numerical calculations.
