By comparing single-particle spectral functions of t-J and Hubbard modelswith recent angle-resolved photoemission (ARPES) results for 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 agiven doping. For dopings greater than about 12% our calculation showsfurthermore that the holes prefer to proliferate out of the metallic stripesinto the neighboring antiferromagnetic domains. The spectra were calculated bya cluster perturbation technique, for which we present an alternativeformulation. Implications for the theory for high-Tc superconductivity arediscussed.Comment: minor changes, some references adde
