Overscreened multi-channel SU(N) Kondo model : large-N solution and Conformal Field Theory
Olivier Parcollet, Antoine Georges, Gabriel Kotliar +1
The multichannel Kondo model with SU(N) spin symmetry and SU(K) channel symmetry is considered. The impurity spin is chosen to transform as an antisymmetric representation of SU(N)…
Transition from overscreening to underscreening in the multichannel Kondo model: exact solution at large N
Olivier Parcollet, Antoine Georges
A novel large-N limit of the multichannel Kondo model is introduced, for representations of the impurity spin described by Schwinger bosons. Three cases are found, associated with…
Kondo Quartet
Antoine Georges, Anirvan Sengupta
This article describes some recently obtained results on the low-energy properties of the "Kondo quartet" model of two spin-1/2 impurities interacting with two channels (flavours)…
