Abstract
The electronic structure and the single-particle spectral density of a stripe arrayformed by ladder-like domain walls (DWs) and by antiferromagnetic (AF) domainsof width two lattice spacings are computed and compared with angle-resolvedphotoemission spectroscopy (ARPES) spectra from some doped cuprates belongingto the 214 family of compounds. We assume that bond order is formed onlegs in DWs and that the phase of the sublattice magnetization changes byπ across each DW. The intensity map plotted in the frame of referencemomentum–energy reproduces quite well the ARPES spectra of Nd-dopedLa2−xSrxCuO4 (LSCO) systems obtained at the doping level of15%. We consider this agreement as an argument for a scenario of coexisting bond-orderedregions and AF regions in the stripe phase of moderately doped cuprates.
