论文摘要
构建了具有通用集成边界字段的量子集成$ d^{（2）} _ 2 $旋转链的精确解。发现该模型的转移矩阵可以分解为两个开放交错各向异性XXZ旋转链的乘积。基于此身份，$ d^{（2）} _ 2 $模型的特征值和伯特ansatz方程是通过off-diagonal bethe ansatz得出的。
Exact solution of the quantum integrable $D^{(2)}_2$ spin chain with generic integrable boundary fields is constructed. It is found that the transfer matrix of this model can be factorized as the product of those of two open staggered anisotropic XXZ spin chains. Based on this identity, the eigenvalues and Bethe ansatz equations of the $D^{(2)}_2$ model are derived via off-diagonal Bethe ansatz.
