Beschreibung

Abstract The success to describe physical properties of conventional hard condensed matter systems by effective downfolded low energy Hamiltonians is remarkable and allows to understand important effects by their effective low energy degrees of freedom. In strongly correlated systems such as transition metal oxides and their relatives, this approach seems to fail as low and high energies as well as the corresponding short and long time scales appear to be strongly coupled. I will outline several experiments where this coupling can be observed and discuss what kind of experimental approaches are needed to improve our understanding of complex condensed matter. Recent experimental approaches such as resonant, and time resolved spontaneous Raman scattering, resonant inelastic light scattering at free electron lasers and time resolved magneto-optical MIR-VUV spectroscopy will be introduced.
