这些是北约高级研究所/欧共体暑期学校关于“强关联系统的新理论方法”的讲座笔记(牛顿研究所，2000年4月)。它们是我两年前为暑期学校写的笔记的续篇，《低维系统的拓扑方面》(Les Houches，1998年7月)。在第二部分中，我回顾了形式因子技术及其对无质量量子场论的扩展。然后讨论了可积量子杂质问题中关联子的计算，特别是分数量子霍尔效应中的点接触隧道效应，以及耗散量子力学的两态问题。
These are notes of lectures given at The NATO Advanced Study Institute/EC Summer School on “New Theoretical Approaches to Strongly Correlated Systems”, (Newton Institute, April 2000). They are a sequel to the notes I wrote two years ago for the Summer School, “Topological Aspects of Low Dimensional Systems”, (Les Houches, July 1998). In this second part, I review the form-factors technique and its extension to massless quantum field theories. I then discuss the calculation of correlators in integrable quantum impurity problems, with special emphasis on point contact tunneling in the fractional quantum Hall effect, and the two-state problem of dissipative quantum mechanics.
