Excitations and correlation in many-body systems
Correlation spectroscopy
A major activity is devoted to the understanding of the nature of electron-electron interaction in atomic, molecular and condensed matter systems. In particular, we investigate in close cooperation with experiment the manifestation of electronic correlation in the two-particle spectrum measured in coincidence experiments. We utilize a variety of techniques ranging from fully numerical density-based and wave-function-based methods to many-body model calculations.
Corals and clusters on surfaces
We also do research on the electronic and magnetic properties of confined electronic systems such as corals and clusters at surfaces and multilayer structures.
