Hund's coupling key role in multi-orbital correlations
Luca de' Medici
We show how in multi-band materials, the Hund's coupling plays a crucial role in tuning the degree of electronic correlation. While in half-filled systems it enhances the correlati…
Role of oxygen-oxygen hopping in the three-band copper-oxide model: quasiparticle weight, metal insulator and magnetic phase boundaries, gap values and optical conductivity
Xin Wang, Luca de' Medici, Andrew J. Millis
We investigate the effect of oxygen-oxygen hopping on the three-band copper-oxide model relevant to high- cuprates, finding that the physics is changed only slightly as the ox…
Genesis of coexisting itinerant and localized electrons in Iron Pnictides
Luca de' Medici, Syed R. Hassan, Massimo Capone
We show how the general features of the electronic structure of the Fe-based high-Tc superconductors are a natural setting for a selective localization of the conduction electrons…
Theory of oxygen K-edge x-ray absorption spectra of cuprates
Xin Wang, Luca de' Medici, A. J. Millis
The dynamical mean-field theory of the three-band model of copper-oxide superconductors is used to calculate the doping dependence of the intensity of the oxygen K-edge x-ray absor…
