Workshop Two-particle correlations
The workshop "Two-particle correlation functions of many-electron systems" was held online May 16-18 2022. An important goal of the workshop was to provide young researchers with an opportunity to present their research to the community. The table below contains a list of speakers and titles. The workshop was organized by Erik van Loon (Lund University) and Alessandro Toschi (TU Wien).
