带边界sine-Gordon模型中的无穷维反射矩阵

Infinite dimension reflection matrices in the sine-Gordon model with a boundary

E. Corrigan, C. Zambon

摘要:

本文以正弦-戈登模型为例,提出了一种求解半直线理论可积边界条件的新方法。其主要思想是探索的后果,考虑到拓扑电荷驻留在边界上,它的变化,因为在散装孤子从边界反射的事实。在这种情况下,反射矩阵本质上是无限维的,比两参数Ghoshal-Zamolodchikov反射矩阵更一般,并且与缺陷密切相关。

英文摘要:

Using the sine-Gordon model as the prime example an alternative approach to integrable boundary conditions for a theory restricted to a half-line is proposed. The main idea is to explore the consequences of taking into account the topological charge residing on the boundary and the fact it changes as solitons in the bulk reflect from the boundary. In this context, reflection matrices are intrinsically infinite dimensional, more general than the two-parameter Ghoshal-Zamolodchikov reflection matrix, and related in an intimate manner with defects.
