Excitons, bound pairs of electrons and holes, are the semiconductor equivalents of positronium and can be excited into Rydberg states like most hydrogen-like atomic systems if the semiconductor crystal is of high quality. In the model semiconductor system of Cu2O, where the excitons were first discovered back in the 1950s at the Ioffe Institute by Gross and Karryev, states with principal quantum number up to n=25 could be reached in experiment. Compared to cold atoms, the exciton Rydberg energy ~90 meV is small and provides the opportunity to address all states from the first excited state of the system up to the ionization threshold using a single tunable laser, which opens up the path towards systematic investigation of scaling laws of the properties of Rydberg systems with respect to the principal quantum number. Also other characteristic properties of Rydberg systems like Rydberg blockade can be reproduced in the exciton system.

The aim of the workshop is to bring together researchers from different countries working in the field of Rydberg excitons in cuprous oxide and other semiconductors and discuss the most topical problems in the field.
