我们利用零温极限下量子转移矩阵的形状因子,研究了XXZ链在反铁磁质量区的两点基态关联函数。我们得到了关联函数的新的形式因子级数表示,它不同于从q顶点算符方法或从通常的传递矩阵的代数Bethe Anatz方法得到的那些表示。我们主张我们的新表示在数值上更有效,并允许直接计算两点函数的大距离渐近行为。保持对两点函数的温度修正的控制,我们看到这些是有序的
We use the form factors of the quantum transfer matrix in the zero-temperature limit in order to study the two-point ground-state correlation functions of the XXZ chain in the antiferromagnetic massive regime. We obtain novel form factor series representations of the correlation functions which differ from those derived either from the q-vertex-operator approach or from the algebraic Bethe Ansatz approach to the usual transfer matrix. We advocate that our novel representations are numerically more efficient and allow for a straightforward calculation of the large-distance asymptotic behaviour of the two-point functions. Keeping control over the temperature corrections to the two-point functions we see that these are of order
