Abstract

We consider an \(XYZ\) spin chain within the framework of the generalized algebraic Bethe ansatz. We calculate the actions of monodromy matrix elements on Bethe vectors as linear combinations of new Bethe vectors. We also compute the multiple action of the gauge-transformed monodromy matrix elements on the pre-Bethe vector and express the results in terms of the partition function of the \(8\)-vertex model.

广义代数 Bethe ansatz 中单向矩阵元素的作用

摘要

我们在广义代数 Bethe ansatz 的框架内考虑一条\(XYZ\)自旋链。我们将 Bethe 向量上的单性矩阵元素的作用计算为新 Bethe 向量的线性组合。我们还计算了规范变换单向矩阵元素对前 Bethe 向量的多重作用,并用\(8\)顶点模型的配分函数表示结果。
