  We use cellular dynamical mean-field theory with extended unit cells to study
the ground state of the two-dimensional repulsive Hubbard model at finite
doping. We calculate the energy of states with d-wave superconductivity
coexisting with spatially uniform magnetic order and find that they are
energetically favoured in a large doping region as compared to the uniform
solution. We study the spatial form of the superconducting and magnetic order
parameters at different doping values.
