摘要:

本文证明了XXZ自旋- $\frac12$链在两个一般可积边界作用于Bethe矢量的链段上的转移矩阵所满足的离壳方程。关键的一步是证明一个修改后的创建操作的Bethe矢量的作用的表达式具有一个离壳结构,这导致在相应的传输矩阵的特征值和Bethe方程的非齐次项。

英文摘要:

In this paper, we prove the off-shell equation satisfied by the transfer matrix associated with the XXZ spin-$\frac12$ chain on the segment with two generic integrable boundaries acting on the Bethe vector. The essential step is to prove that the expression of the action of a modified creation operator on the Bethe vector has an off-shell structure which results in an inhomogeneous term in the eigenvalues and Bethe equations of the corresponding transfer matrix.
