                      comments. The work of H. I. was supported by the

      abstract     = {We present an embedding approach based on localized basis
                      functions which permits an efficient application of the
                      dynamical mean-field theory (DMFT) to inhomogeneous
                      correlated materials, such as semi-infinite surfaces and
                      heterostructures. In this scheme, the semi-infinite
                      substrate leads connected to both sides of the central
                      region of interest are represented via complex
                      energy-dependent embedding potentials that incorporate
                      one-electron as well as many-body effects within the
                      substrates. As a result, the number of layers which must be
                      treated explicitly in the layer-coupled DMFT equation is
                      greatly reduced. To illustrate the usefulness of this
                      approach, we present numerical results for strongly
                      correlated surfaces, interfaces, and heterostructures of the
                      single-band Hubbard model.},
