Using an exact diagonalization method within the dynamical mean-field theory we found stable stripe phases in the two-dimensional Hubbard model doped by 0.03<delta<0.2 holes, with a crossover from diagonal to vertical site-centered stripes at doping delta approximately 0.05. The doping dependence of the size of magnetic domains and chemical potential …
