Incommmensurability and unconventional superconductor to insulator transition in the Hubbard model with bond-charge interaction
A. A. Aligia, A. Anfossi, L. Arrachea +6
We determine the quantum phase diagram of the one-dimensional Hubbard model with bond-charge interaction X in addition to the usual Coulomb repulsion U at half-filling. For large e…

Recent results on integrable electronic models
Alberto Anfossi, Fabrizio Dolcini, Arianna Montorsi
We review the approach of generalized permutator to produce a class of integrable quantum Hamiltonians, as well as the technique of Sutherland species (SS) to map a subclass of it…
