Dynamical Mean-Field Approach
with Predictive Power for
Strongly Correlated Materials

Autumn School on Correlated Electrons:
DMFT at 25: Infinite Dimensions

15-19 September 2014, Forschungszentrum Jülich

Scope

Dynamical mean-field theory (DMFT) has opened new perspectives for dealing with strong electronic correlations and the associated emergent phenomena. This successful method has exploited the experience previously gained with single-impurity models (e.g., the Anderson model) transferring it to many-body lattice problems. The basis for this breakthrough was the realization, 25 years ago, that diagrammatic perturbation theory greatly simplifies in the limit of infinite dimensions, so that the self-energy becomes local. Nowadays DMFT, combined with ab-initio density-functional techniques, is the state-of-the art approach for strongly correlated materials. In this school we will present how DMFT is applied to real systems. Lectures will cover the basics of the method, the LDA+DMFT approach, non-local extensions of DMFT, and impurity solvers. Lectures on photoemission spectroscopy, response functions, and time-dependent phenomena provide the necessary contact to experiments.

The goal of the school is to introduce advanced graduate students and up to the modern approaches to the realistic modeling of strongly-correlated systems.
