A novel diagrammatic technique for the single-site Anderson model
V. A. Moskalenko, P. Entel, D. F. Digor +2
A diagrammatic theory around the atomic limit is proposed for the single-impurity Anderson model in which the strongly correlated impurity electrons hybridize with free (uncorrelat…

Single-site Anderson model. II Perturbation theory of symmetric model
V. A. Moskalenko, P. Entel, D. F. Digor +2
The strong electron correlations caused by Coulomb interaction of impurity electrons are taken into account. The infinite series of diagrams containing irreducible Green's function…
