Short Summary

It is intended to combine scanning and near-field light scattering techniques for studying the charge, spin, and lattice dynamics of correlated electron systems. The combination facilitates the simultaneous analysis of single- and two-particle spectroscopies at identical positions of a surface. This enables one to reveal the impact of electronic correlations on the materials properties close to magnetic textures, surfaces, defects, and interfaces.
