Lda+dmft: from Bulk to Heterostructures: Realistic Calculations and Novel Methods for the Treatment of Electronic Correlation in Solids Philipp Hansmann

Theoretical modeling and analysis of strongly correlated electron systems is currently one of the biggest challenges in condensed matter physics. Due to their fascinating physics they have become the focus of attention during the past decades. Rich phase diagrams display competition of many unusual, often exotic, ground states. The combination of ab initio density-functional methods like the local density approximation (LDA) with dynamical mean field theory (DMFT) allows for a realistic and accurate description of compounds in which electronic correlations have a large impact. In this work we analyze different correlated systems by means of state-of-the-art theoretical methods and, moreover, implement methodological extensions necessary to treat a wider family of compounds.
