Quantum Thermalization beyond Non-Integrability and Quantum Scars in a Multispecies Bose-Josephson Junction
Francesco Di Menna, Sergio Ciuchi, Simone Paganelli
The modern framework for quantum thermalization is grounded in the Eigenstate Thermalization Hypothesis (ETH), in which non-integrability and chaos are historically assumed as prer…
Majorana fermions at self-generated interfaces
Nikola Prodanov, Sergio Ciuchi, Sergio Caprara
The Kitaev model describing a one-dimensional topological superconducting chain is known to support two Majorana fermions localized at the systems endpoints when the parameters are…
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…
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…
Fragility of local moments against hybridization with flat bands
Max Fischer, Arianna Poli, Lorenzo Crippa +6
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…
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…
