Diagrammatic theory for twofold degenerate Anderson impurity model
V. A. Moskalenko, L. A. Dohotaru, D. F. Digor +1
The twofold degenerate Anderson impurity model [1-4] is investigated and the strong electronic correlations of d-electrons of impurity ion are taken into account by elaborating sui…
Diagrammatic analysis of the Hubbard model II: Superconducting state
V. A. Moskalenko, L. A. Dohotaru, D. F. Digor +1
Diagrammatic analysis for normal state of Hubbard model proposed in our previous paper [1] is generalized and used to investigate superconducting state of this model. We use the no…
Diagrammatic analysis of the Hubbard model:Stationary property of the thermodynamic potential
V. A. Moskalenko, L. A. Dohotaru, I. D. Cebotari
Diagrammatic approach proposed many years ago for strong correlated Hubbard model is developed for analyzing of the thermodynamic potential properties. The new exact relation betwe…
Diagrammatic theory for Periodic Anderson Model: Stationary property of the thermodynamic potential
V. A. Moskalenko, L. A. Dohotaru, R. Citro
Diagrammatic theory for Periodic Anderson Model has been developed, supposing the Coulomb repulsion of localized electrons as a main parameter of the theory. electrons ar…
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…
