Abstract

The momentum and energy dependence of the weight distribution in the vicinity of the one-electron spectral-function singular branch lines of the ID Hubbard model is studied for all values of the electronic density and on-site repulsion U. To achieve this goal, we use the recently introduced pseudofermion dynamical theory. Our predictions agree quantitatively for the whole momentum and energy bandwidth with the peak dispersions observed by angleresolved photoelectron spectroscopy in the quasi-1D organic conductor TTF-TCNQ.
