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…

Quantum Magnets with Anisotropic Infinite Range Random Interactions
Liliana Arrachea, Marcelo J. Rozenberg
Using exact diagonalization techniques we study the dynamical response of the anisotropic disordered Heisenberg model for systems of S=1/2 spins with infinite range random exchange…

Exact Solution of a Hubbard Chain with Bond-Charge Interaction
A. A. Aligia, L. Arrachea
We obtain the exact solution of a general Hubbard chain with kinetic energy , bond-charge interaction and on-site interaction with the only restriction . At zero…
