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…

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…

Interacting nodal semimetals with non-linear bands
Arianna Poli, Niklas Wagner, Max Fischer +3
We investigate the quasi-particle and transport properties of a model describing interacting Dirac and Weyl semimetals in the presence of local Hubbard repulsion , where we expl…
