Application of Closed Orbit Theory to Magnetoexcitons in Cuprous Oxide — •Jonathan Luft genannt Philipps, Jörg Main, and Günter Wunner — 1. Institut für Theoretische Physik, Universität Stuttgart, Germany

Highly excited excitons in cuprous oxide can be described as hydrogen-like Rydberg systems. As there are many semiclassical approaches for the description of the hydrogen atom, we want to apply the closed orbit theory to describe the excitons in cuprous oxide. In contrast to hydrogen atoms, describing these excitons is more challenging due to the underlying band structure. Via calculating the classical trajectories of these highly excited excitons and applying closed orbit theory, we are able to determine the semiclassical photoabsorption spectra. The resulting absorption spectra will be compared with experimental results.
