Klaus Richter

Klaus Richter has held a chair in condensed-matter theory at the University of Regensburg in Germany since 2001. His group, Complex Quantum Systems, conducts research in the fields of solid-state and cold-atom physics as well as many-body quantum chaos. After obtaining his PhD at the University of Freiburg, Germany, in 1991 and postdoctoral stays in Paris and Augsburg, Germany, he was a group leader at the Max Planck Institute for the Physics of Complex Systems, also in Germany. He was awarded the Dresden Physics Prize in 2019 and the title Professor of the Year (in Germany) by the UNICUM Foundation in 2022. From 2024 to 2026 he was president of the German Physical Society, of which he is presently vice president.
