Dimerization process and elementary excitations in spin-Peierls chains coupled by frustrated interactions
D. Mastrogiuseppe, C. Gazza, A. Dobry
We consider the ground state and the elementary excitations of an array of spin-Peierls chains coupled by elastic and magnetic interactions. It is expected that the effect of the m…

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…

Stripe Stability in the Extended t-J Model on Planes and Four-Leg Ladders
T. Tohyama, C. Gazza, C. T. Shih +4
The tendencies to phase-separation and stripe formation of the t-J model on planes and four-leg ladders have been here reexamined including hole hopping terms t', t'' beyond neares…
