Electronic screening and correlated superconductivity in carbon nanotubes
S. Bellucci, M. Cini, P. Onorato +1
A theoretical analysis of the superconductivity observed recently in Carbon nanotubes is proposed. We argue that ultra-small (diameter ) single wall carbon nanotubes…
Correlated Nanoscopic Josephson Junctions
Stefano Bellucci, Michele Cini, Pasquale Onorato +1
We discuss correlated lattice models with a time-dependent potential across a barrier and show how to implement a Josephson-junction-like behavior. The pairing occurs by a correlat…
Suppression of electron-electron repulsion and superconductivity in Ultra Small Carbon Nanotubes
S. Bellucci, M. Cini, P. Onorato +1
Recently, ultra-small-diameter Single Wall Nano Tubes with diameter of have been produced and many unusual properties were observed, such as superconductivity, leadi…
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…
Repulsion-Sustained Supercurrent and Flux Quantization in Rings of Symmetric Hubbard Clusters
Agnese Callegari, Michele Cini, Enrico Perfetto +1
We test the response to a threading magnetic field of rings of 5-site -symmetric repulsive Hubbard clusters connected by weak intercell links; each 5-site unit has the topo…
