ARPES on Complex Systems

The research activities of our group focus on the study of the structural, electronic, and magnetic properties of novel complex systems and nanostructured materials. Our goals are, on the one hand, to determine the suitability of the current approaches in the quantum theory of solids and develop new intuitions and understanding; on the other hand, to explore new pathways for the fabrication of materials and structures with innovative physical properties.

One key to overcome this challenge is understanding the low-energy electronic structure and the interplay between the spin, charge, and orbital degrees of freedom, which in turns determines the macroscopic physical properties. This requires the use of some of the most powerful electron spectroscopy techniques such as, in particular, angle-resolved photoelectron spectroscopy (ARPES – a state of the art system is currently under development in our group), but also electron energy loss spectroscopy (EELS), X-ray absorption spectroscopy, and resonant X-ray scattering.
