Dynamical vertex approximation for retarded interactions: Application to the Hubbard-Holstein model
Emin Moghadas, Samuele Giuli, Massimo Capone +1
We extend the dynamical vertex approximation (DA), in its most commonly used ladder-version, to systems with retarded electronic interactions. Such an extended scheme, which we…
Ghost-RISB for Correlated Electron-Phonon Systems: Application to the Hubbard-Holstein Model
Samuele Giuli, Ricardo J. Campos-Lopes, Emin Moghadas +1
We develop a generalization of the ghost-rotationally-invariant slave-boson (ghost-RISB) method that incorporates local phonon modes coupled to arbitrary on-site electronic degrees…
Effective enhancement of the electron-phonon coupling driven by nonperturbative electronic density fluctuations
Emin Moghadas, Matthias Reitner, Tim Wehling +3
We present a dynamical mean-field study of the nonperturbative electronic mechanisms, which may lead to significant enhancements of the electron-phonon coupling in correlated elect…
Compressing the two-particle Green's function using wavelets: Theory and application to the Hubbard atom
Emin Moghadas, Nikolaus Dräger, Alessandro Toschi +7
Precise algorithms capable of providing controlled solutions in the presence of strong interactions are transforming the landscape of quantum many-body physics. Particularly exciti…
