Conformal Field Theory Approach to the Kondo Effect
Ian Affleck
Recently, a new approach, based on boundary conformal field theory, has been applied to a variety of quantum impurity problems in condensed matter and particle physics. A particula…

Is there an exponentially large Kondo screening cloud ?
Erik Sorensen, Ian Affleck
We make a precise scaling conjecture, based on renormalization group ideas, regarding the screening cloud around an impurity spin in the Kondo effect and test it numerically using…

Phase Transitions in the One-Dimensional Pair-Hopping Model: a Renormalization Group Study
Arnold Sikkema, Ian Affleck
The phase diagram of a one-dimensional tight-binding model with a pair-hopping term (amplitude V) has been the subject of some controvery. Using two-loop renormalization group equa…
