Theory of Strongly Correlated Materials

	RESEARCH

We are generally aiming at reaching a deeper understanding of real condensed matter systems from a microscopic point of view. In this regard, the main concern is the electronic structure. As the latter shows in the most interesting cases a complex many-particle character, combining realistic band-structure methods with approaches from many-body theory is one major goal of our research.

Some general topics/frameworks are:

• Density Functional Theory (DFT) in various flavors
• Dynamical Mean-Field Theory (DMFT) and its combination with DFT
• Basis Sets for the correlated electronic structure problem (Wannier functions, etc.)
• Slave-Boson Theory
• Quantum-Monte-Carlo Methods
• Cluster Expansion Technique and Cluster Variation Method
