Many Body Physics Group

The Many Body Physics Group's research concentrates on condensed matter theory. In particular, we investigate equilibrium and nonequilibrium properties of systems with strong correlations, such as high-temperature superconducting cuprates and pnictides, manganates, oxide heterostructures, nanostructured devices, as well as "artificial" crystals obtained by ultracold atoms in optical lattices. We employ a variety of methods, ranging from fully ab-initio density functional calculations, to mixed DFT+many body approaches such as dynamical mean-field theory or the cluster-embedding methods, to Matrix Product State techniques for model Hamiltonians. We also work on the development of new algorithms for the numerical simulation of correlated electron systems. Here is a list of our current research topics:

LDA + DMFT studies of novel transition metal oxides and topological materials (Markus Aichhorn)
Quantum many-body systems out of equilibrium (Enrico Arrigoni, Wolfgang von der Linden, Hans-Gerd Evertz)
Ab-initio studies of novel materials - oxide heterostructures and superconductors (Lilia Boeri)
Quantum Impurity Solvers (Hans-Gerd Evertz)

Our research is supported by several projects funded by the Austrian Science Fund (FWF):
