"Superconductor"-insulator transitions in a Hubbard chain with nearest- neighbor and bond-charge interactions
A. A. Aligia, E. R. Gagliano
We consider a half-filled generalized Hubbard chain with electron-hole symmetric correlated hopping and on-site and nearest-neighbor repulsions U and V respectively. In addition to…

Optical properties of an effective one-band Hubbard model for the cuprates
M. E. Simon, A. A. Aligia, E. R. Gagliano
We study the Cu and O spectral density of states and the optical conductivity of CuO_2 planes using an effective generalized one-band Hubbard model derived from the extended three-…
