Conformal-Field-Theory Approach to Quantum-Impurity Problems

  • Conference paper
Correlation Effects in Low-Dimensional Electron Systems

Part of the book series: Springer Series in Solid-State Sciences ((SSSOL,volume 118))

Abstract

A brief review is given of a new method for studying the critical behavior of quantum impurity problems, based on conformal field theory techniques, which I developed with Andreas Ludwig. Some results on the overscreened Kondo problem are reviewed. It is shown that the simple open and periodic fixed points, which occur in quantum spin chain impurity models, are related to each other by fusion.
