    • Thus, a gap may open at (Formula presented) once couplings and lattice sizes are reached where pairing effects are important. We have observed such effects in our studies, but we also found that at (Formula presented) the DOS has a sharp peak. Then, the numerically observed ladder DOS peak cannot be attributed exclusively to a BCS redistribution of spectral weight upon doping
    • Note that pairing on ladders may exist [see E. Dagotto and T. M. Rice, Science 271, 618 (1996) and references therein]. Thus, a gap may open at (Formula presented) once couplings and lattice sizes are reached where pairing effects are important. We have observed such effects in our studies, but we also found that at (Formula presented) the DOS has a sharp peak. Then, the numerically observed ladder DOS peak cannot be attributed exclusively to a BCS redistribution of spectral weight upon doping.

    • This is not in contradiction with the observation of (Formula presented)-wave SC at quarter-filling reported in E. Dagotto and J. Riera, Phys. Rev. Lett. 70, 682 (1993), since these results were obtained at large (Formula presented).
