W=0 pairing in Hubbard and related models of low-dimensional superconductors
Adalberto Balzarotti, Michele Cini, Enrico Perfetto +1
Lattice Hamiltonians with on-site interaction have W=0 solutions, that is, many-body {\em singlet} eigenstates without double occupation. In particular, W=0 pairs give a clue t…
Microscopic Model for a Strongly Correlated Superconducting Single-Electron-Transistor
Enrico Perfetto, Michele Cini
We model a Superconducting Single-Electron Transistor operating by repulsive interactions. The device consists of a ring of Hubbard clusters, placed between electrodes and capaciti…
Electron-Phonon Interactions in the W=0 Pairing Scenario
Enrico Perfetto, Michele Cini
We investigate the interplay of phonons and correlations in superconducting pairing by introducing a model Hamiltonian with on-site repulsion and couplings to several vibration bra…
Pairing in Cu-O Models: Clues of Joint Electron-Phonon and Electron-Electron Interactions
Enrico Perfetto, Michele Cini
We discuss a many-electron Hamiltonian with Hubbard-like repulsive interaction and linear coupling to the phonon branches, having the Cu-O plane of the superconducting cuprates as…
