Abstract

By comparing single-particle spectral functions of t\ensuremath-J and Hubbard models with recent angle-resolved photoemission results for La_2\ensuremath-xSr_xCuO₄ (LSCO) and Nd-LSCO, we can decide where holes go as a function of doping, and more specifically, which type of stripe (bond-, site-centered) is present in these materials at a given doping. For dopings greater than about 12% our calculation shows that the holes prefer to proliferate out of the metallic stripes into the neighboring antiferromagnetic domains. The spectra were calculated by a cluster-perturbation technique, for which we present an alternative formulation. Implications for the theory for high\ensuremath-T_c superconductivity are discussed.
