Strong Correlations in Electron Doped Phthalocyanine Conductors Near Half Filling
Erio Tosatti, Michele Fabrizio, Jaroslav Tobik +1
We propose that electron doped nontransition metal-phthalocyanines (MPc) like ZnPc and MgPc, similar to those very recently reported, should constitute novel strongly correlated me…
Variational description of Mott insulators
Manuela Capello, Federico Becca, Michele Fabrizio +2
The Gutzwiller wave function for a strongly correlated model can, if supplemented with a long-range Jastrow factor, provide a proper variational description of Mott insulators, so…
Spectral properties of a two-orbital Anderson impurity model across a non-Fermi liquid fixed point
Lorenzo De Leo, Michele Fabrizio
We study by NRG the spectral properties of a two-orbital Anderson impurity model in the presence of an exchange splitting which follows either regular or inverted Hund's rules. The…
Strongly Correlated Superconductivity and Pseudogap Phase near a multi-band Mott Insulator
M. Capone, M. Fabrizio, C. Castellani +1
Near a Mott transition, strong electron correlations may enhance Cooper pairing. This is demonstrated in the Dynamical Mean Field Theory solution of a twofold-orbital degenerate Hu…
