Autumn-School Hands-on LDA+DMFT

4 - 7 October 2011, Jülich

Scope

Soon after the discovery of quantum mechanics, it became evident that the fundamental obstacle to explaining the properties of solids from first-principles is the description of electronic many-body effects. A crucial step forward was density-functional theory (DFT) and its local-density approximation (LDA). The success of DFT in explaining the physical and chemical properties of solids is so remarkable, that DFT is considered the standard model of solid-state physics. Nevertheless, LDA and its generalizations fail for systems in which electrons lose their individuality and whose low-energy properties are dominated by electron-electron correlations: Mott-insulating transition-metal oxides, Kondo and heavy- fermion materials, organic crystals, and many others. The realistic description of such strongly-correlated materials remains, to date, one of the grand-challenges of condensed matter-physics.
During the last years a major breakthrough came with the development of the LDA+DMFT method. In this approach, conventional ab-initio schemes based on DFT/LDA are combined with a modern many-body approach, the dynamical mean-field theory (DMFT).
The present school aims to introduce students starting from the advanced graduate level to this state-of-the-art approach.
