Interplay of Orbital Degeneracy and Superconductivity in a Molecular Conductor
Michele Fabrizio, Marco Airoldi, Erio Tosatti
We study electron propagation in a molecular lattice model. Each molecular site involves doubly degenerate electronic states coupled to doubly degenerate molecular vibration, leadi…

The Phase Diagram of Correlated Electrons in a Lattice of Berry Molecules
Giuseppe Santoro, Marco Airoldi, Nicola Manini +2
A model for correlated electrons in a lattice with local additional spin--1 degrees of freedom inducing constrained hopping, is studied both in the low density limit and at quarter…
