Abstract
Using an exact diagonalization method within the dynamical mean-field theory we found stable stripe phases in the two-dimensional Hubbard model doped by holes, with a crossover from diagonal to vertical site-centered stripes at doping . The doping dependence of the size of magnetic domains and chemical potential shift are in quantitative agreement with the experimental results for . The one-dimensional metallic behavior along the domain walls explains the observed suppression of spectral weight along the Brillouin zone diagonal.
