Session Abstract

Traditionally crystallography was concerned with diffraction patterns exhibiting a set of distinct Bragg peaks. Following the discovery of quasicrystals a lot of different aperiodic structures and their diffraction patterns have been studied. Apart from pure point diffraction, systems with purely singular or absolutely continuous spectrum have been found, as well as systems with mixed spectra. On the other hand, experimentalists become more and more interested in diffuse scattering. Although a lot of progress has been made in the last decades, our knowledge of matter and its diffraction properties is still far from complete. This microsymposium intends to bring together mathematicians and experimentalists to present their new results and exchange ideas to improve our understanding of the various kinds of diffraction spectra.
