Abstract
For an infinite linear chain we consider the atomic limit of an extended Hubbard model which take into account the nearest-neighbor interatomic electron-electron repulsion. The specific heat, static magnetic susceptibility, and density-density correlation function are studied exactly at any temperature for the half-filled-band case. We discuss also the quarter-filled band in the limit of infinite intra-atomic Coulomb repulsion.Keywords
