摘要:

研究了sl(n)和sl(m)的两种边界条件(“孤子保持”和“孤子不保持”)|n)开自旋链。适当的反射方程制定和相应的解决方案进行了分类。的对称性和Bethe Answer方程推导出每种情况下。给出了“孤子保持”情形下非对角反射矩阵的一般处理方法。讨论了“孤子非保持”边界条件与扭曲(超)杨格尔方程之间的联系。

英文摘要:

Two types of boundary conditions ("soliton preserving" and "soliton non-preserving") are investigated for the sl(n) and sl(m|n) open spin chains. The appropriate reflection equations are formulated and the corresponding solutions are classified. The symmetry and the Bethe Ansatz equations are derived for each case. The general treatment for non-diagonal reflection matrices associated to "soliton preserving" case is worked out. The connection between the "soliton non-preserving" boundary conditions and the twisted (super) Yangians is also discussed.
