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…
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…
Interaction of strongly correlated electrons and acoustical phonons
V. A. Moskalenko, P. Entel, D. F. Digor
We investigate the interaction of correlated electrons with acoustical phonons using the extended Hubbard-Holstein model in which both, the electron-phonon interaction and the on-s…
Strong interaction of correlated electrons with phonons: Exchange of phonon clouds by polarons
V. A. Moskalenko, P. Entel, M. Marinaro +1
We investigate the interaction of strongly correlated electrons with phonons in the frame of the Hubbard-Holstein model. The electron-phonon interaction is considered to be strong…
