Role of the impurity-potential range in disordered d-wave superconductors
Luca Dell'Anna, Michele Fabrizio, Claudio Castellani
We analyze how the range of disorder affects the localization properties of quasiparticles in a two-dimensional d-wave superconductor within the standard non-linear sigma-model app…
Jastrow theory of the Mott transition in bosonic Hubbard models
Manuela Capello, Federico Becca, Michele Fabrizio +1
We show that the Mott transition occurring in bosonic Hubbard models can be successfully described by a simple variational wave function that contains all important long-wavelength…
Extended Gutzwiller wavefunction for the Hubbard-Holstein model
P. Barone, R. Raimondi, M. Capone +2
We introduce a new type of Gutzwiller variational wavefunction for correlated electrons coupled to phonons, able to treat on equal footing electronic and lattice degrees of freedom…
