Conformal Field Theory Approach to the Two-channel Anderson Model
arXiv:cond-mat/0502646 · doi:10.1016/j.jmmm.2003.12.1232
Abstract
The two-channel Anderson impurity model serves as a prototype for describing heavy-fermion materials with a possible mixed-valent regime with both quadrupolar and magnetic character. We report on the low-energy physics of the model, using a conformal field theory approach with exact Bethe Ansatz results as input.
