Selective d-state Conduction Blocking in Nickel Nanocontacts
A. Smogunov, A. Dal Corso, E. Tosatti
The lowest conductance step for a Ni nanocontact is anomalously small in comparison with the large expected number of conducting channels. We present electronic structure calculati…
Bending strain-driven modification of surface reconstructions: Au(111)
U. Tartaglino, E. Tosatti, D. Passerone +1
Strain can affect the morphology of a crystal surface, and cause modifications of its reconstruction even when weak, as in the case of mechanical bending. We carried out calculatio…
Superconductivity Near Ferromagnetism in MgCNi3
H. Rosner, R. Weht, M. D. Johannes +2
An unusual quasi-two-dimensional heavy band mass van Hove singularity (vHs) lies very near the Fermi energy in MgCNi3, recently reported to superconduct at 8.5 K. This compound is…
Electron-vibration coupling constants in positively charged fullerene
Nicola Manini, Andrea Dal Corso, Michele Fabrizio +1
Recent experiments have shown that C60 can be positively field-doped. In that state, fullerene exhibits a higher resistivity and a higher superconducting temperature than the corre…
Two-Stage Rotational Disordering of a Molecular Crystal Surface: C60
C. Laforge, D. Passerone, A. B. Harris +2
We propose a two-stage mechanism for the rotational surface disordering phase transition of a molecular crystal, as realized in C fullerite. Our study, based on Monte Carlo…
Direct Transition Between a Singlet Mott Insulator and a Superconductor
M. Capone, M. Fabrizio, E. Tosatti
We argue that a normal Fermi liquid and a singlet, spin gapped Mott insulator cannot be continuously connected, and that some intermediate phase must intrude between them. By expli…
