量子复数sine-Gordon缀饰边界

Quantum complex sine-Gordon dressed boundaries

Peter Bowcock, James Umpleby

摘要:

在本文中,我们研究的量子反射因子的CSG修饰边界,以前构造的Dirichlet边界与可积CSG缺陷。我们分析了经典束缚态,用半经典方法研究了量子边界谱。我们猜想一个粒子在非激发边界上反射的全量子反射矩阵。利用反射和边界自举方程,构造了电荷Q=+n孤子从第m个激发边界反射的反射矩阵.证据支持我们的猜想是通过检查,引导关闭,反射矩阵同意与已知的结果在经典的限制。本文对Coleman-Thun图中反射矩阵的极点作了部分分析。

英文摘要:

In this paper we investigate the quantum reflection factor for the CSG dressed boundary, previously constructed by dressing the Dirichlet boundary with the integrable CSG defect. We analyse classical bound states and use semi-classical methods to investigate the quantum boundary spectrum. We conjecture a fully quantum reflection matrix for a particle reflecting from an unexcited boundary. By using the reflection and boundary bootstrap equations, the reflection matrix for a charge Q=+n soliton reflecting from the mth excited boundary is constructed. Evidence supporting our conjecture is given by checking that the bootstrap closes and that the reflection matrices agrees with known results in the classical limit. A partial analysis of the poles in the reflection matrices which arise from Coleman-Thun diagrams is given.
