摘要: We investigate the one-dimensional (1D) Hubbard model with an additional bond-charge interaction, recently considered in description of compounds that exhibit strong 1D features above temperature ordered phases. The partition function is exactly calculated for a value coupling; behavior specific heat and spin susceptibility as derived at arbitrary filling, particularly discussed across occurring metal-insulator transition. results show terms weaken excitations system.
