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…
Minimal Theory of Strange Carriers
Simone Fratini
I explore a theory of transport and optical properties of strange metallic carriers in strongly correlated systems that follows from assuming that the diffusion constant has reache…
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…
Displaced Drude peak and bad metal from the interaction with slow fluctuations
S. Fratini, S. Ciuchi
Scattering by slowly fluctuating degrees of freedom can cause a transient localization of the current-carrying electrons in metals, driving the system away from normal metallic beh…
Geometrical frustration effects on charge-driven quantum phase transitions
L. Cano-Cortes, A. Ralko, C. Fevrier +2
The interplay of Coulomb repulsion and geometrical frustration on charge-driven quantum phase transitions is explored. The ground state phase diagram of an extended Hubbard model o…
