We present a self-consistent method for using real-space dynamical mean-field theory (r-DMFT) to address local and intersite Coulomb interactions in heterostructures. The local in-plane many-body problem is solved using the continuous-time quantum Monte Carlo approach for the Hubbard model in hybridization expansion (CT-Hyb). The mean-field interlayer Coulomb potential generates a classical electrostatic problem which is solved by employing the Poisson equation for the multilayered geometry. Using this method we study half-metallic heterostructures consisting of coupled layers of single-band Hubbard models.
