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 $t$ , bond-charge interaction $X$ and on-site interaction $U$ with the only restriction $t = X$ . At zero…

Superconductivity in the cuprates

C. D. Batista, A. A. Aligia

We evaluate numerically several superconducting correlation functions in a generalized $t - J$ model derived for hole-doped CuO $_{2}$ planes. The model includes a three-site term $t^{''}$ …
