A diagrammatic solution of the single‐impurity Anderson model in the Kondo regime
- Conference date: 2-13 October 2006
- Location: Salerno (Italy)
We study the single‐impurity Anderson model with diagrammatic techniques. We employ the parquet approach to determine the electron‐hole and electron‐electron irreducible vertices self‐consistently. We demonstrate that when the dominant contributions from the critical region of the singularity driven by multiple electron‐hole scatterings are properly taken into account we make the parquet equations soluble and recover the Kondo asymptotics in the symmetric as well as in the asymmetric cases.
