摘要:

本文在代数Bethe Answer框架下研究了具有对角边界条件的XXZ自旋链。使用显式计算的Bethe状态的标积和一个重访版本的散装逆问题,我们计算的关联函数的基本积木。在半无限链的极限下,它们可以作为一般函数的重积分得到,类似于周期边界条件的情况。

英文摘要:

We consider the XXZ spin chain with diagonal boundary conditions in the framework of algebraic Bethe Ansatz. Using the explicit computation of the scalar products of Bethe states and a revisited version of the bulk inverse problem, we calculate the elementary building blocks for the correlation functions. In the limit of half-infinite chain, they are obtained as multiple integrals of usual functions, similar to the case of periodic boundary conditions.
