Density-functional theory (DFT) is considered the Standard Model of solid-state physics. The state-of-the art approximations to DFT, the local-density approximation (LDA) or its simple extensions, fail, however, even qualitatively, for strongly-correlated systems.
When correlations are strong, electrons lose their individuality, and novel properties emerge. Mott transitions, Kondo and heavy-fermion behavior, non-conventional superconductivity and orbital order are just some examples of this emergent behavior.
The realistic description of emergent properties is one of the grand-challenges of modern condensed-matter physics. To understand this physics beyond the Standard Model, non-perturbative many-body techniques are essential. Still, DFT-based methods are needed to devise materials-specific models of strong correlations. Mastering these novel techniques requires a vast background, ranging from DFT to model building and many-body physics.
The aim of this school is to introduce advanced graduate students and up to the modern methods for modeling emergent properties of correlated electrons and to explore the relation of electron correlations with quantum entanglement and concepts from quantum information.
