Abstract of the talk:

We present a self-consistent method for using real space dynamical mean-field theory (r-DMFT) to address local and intersite Coulomb interactions in heterostrcutures. 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 solved by the Poisson equation for the multilayered geometry. Using this method we study half-metallic heterostructures made of coupled layers of single-band Hubbard models. A similar setup for non-magnetic heterostructures turns out to be a useful playground to investigate the validity of the Friedel sum rule.
