Progress and problems of DFT+DMFT approach — •Alexander Lichtenstein — Institute of Theoretical Physics, University of Hamburg, 20355 Hamburg

Effects of strong electron correlations in real materials can be described within the QMC, GW or DFT+DMFT methods. We discuss recent progress of realistic Dynamical Mean Field Theory of complex systems including oxides and magnetic nanomaterials. Possible future directions to overcome standard problems of the DFT+DMFT scheme and to include non-local correlation effects will be reviewed.
