Abstract
The single-particle Green's function for a striped t-J model is calculated using cluster a perturbation theory, where short-distance effects are accou nted for by exact cluster diagonalization and long-distance effects by pert urbation (in the hopping). Both site-centered and bond-centered stripe scen arios have been studied. The data for site-centered stripes quantitatively reproduce salient (ARPES-) features.
