Inelastic scattering and transient localization from coupling to two-level systems
Hadi Rammal, Sergio Ciuchi, Simone Fratini
We consider an electron interacting locally with two-level systems (TLSs) as an archetypal model for charge transport in the presence of inelastic scatterers. To assess the importa…
Fragility of local moments against hybridization with flat bands
Max Fischer, Arianna Poli, Lorenzo Crippa +5
The Kondo screening of a localized magnetic moment crucially depends on the spectral properties of the electronic bath to which it is coupled. Unlike textbook examples, realistic s…
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…
Stabilization of Fermi-liquid behavior by interactions in disordered metals
Arianna Poli, Simone Fratini, Jennifer Coulter +2
We study the interplay of electron-electron and electron-disorder scattering in correlated Fermi liquids by the disordered Hubbard model using dynamical mean-field theory with an I…
Strange metal transport from coupling to fluctuating spins
Simone Fratini, Ivan Duchemin, Arnaud Ralko +1
Metals hosting strong electronic interactions, including high-temperature superconductors, behave in ways that do not conform to normal Fermi liquid theory. To pinpoint the microsc…
Transient localization from the interaction with quantum bosons
H. Rammal, A. Ralko, S. Ciuchi +1
We carefully revisit the electron-boson scattering problem, going beyond popular semi-classical treatments. By providing numerically exact results valid at finite temperatures, we…
