关于半动力反射方程:解与结构矩阵

On the semi-dynamical reflection equation: solutions and structure matrices

J. Avan, C. Zambon

摘要:

构造了非常数半动力反射方程的显式解,并对其结构矩阵进行了适当的参数化。考虑具有有理非常数Arutyunov-Chekhov-Frolov结构矩阵的半动力反射方程和一个具体的亚纯映射,发现只有两组已知的常数解可推广到非常数情形.为了简化未来的自旋链哈密顿量的建设,参数化程序明确适用于所有元素的半动态反射方程。对于“twists”和R-矩阵,我们发现了一些有趣的表达式,特别是R-矩阵的一些表达式似乎是第一次出现在这里。此外,还得到了半动态反射方程的一组新的相容结构矩阵。

英文摘要:

Explicit solutions of the non-constant semi-dynamical reflection equation are constructed, together with suitable parametrizations of their structure matrices. Considering the semi-dynamical reflection equation with rational non-constant Arutyunov-Chekhov-Frolov structure matrices, and a specific meromorphic ansatz, it is found that only two sets of the previously found constant solutions are extendible to the non-constant case. In order to simplify future constructions of spin-chain Hamiltonians, a parametrization procedure is applied explicitly to all elements of the semi-dynamical reflection equation available. Interesting expressions for `twists' and R-matrices entering the parametrization procedure are found. In particular, some expressions for the R-matrices seem to appear here for the first time. In addition, a new set of consistent structure matrices for the semi-dynamical reflection equation is obtained.
