From science to sports – a new in-house event fostered collaboration, dialogue, and community spirit across all departments. more

On October 8, 2025, the Department of Quantum Many-Body Theory at the Max Planck Institute for Solid State Research hosted the Japanese–German Symposium on Geometry and Topology of Quantum Materials. Around 70 participants from Stuttgart and other institutions joined the one-day meeting to explore recent developments in quantum geometry, topology, and their connection to correlated materials. more

Studying the properties of Ta₂NiSe₅ to test the hypothesis that its ground state is an excitonic insulator has been a decade-long research project combining the efforts of our research groups from two departments at the Max Planck Institute for Solid State Research: Solid State Spectroscopy (Bernhard Keimer) and Quantum Materials (Hidenori Takagi), together with the Scientific Facility Crystal Growth. Our recent experiments on Raman scattering under uniaxial compressive strain reveal enhanced excitonic fluctuations accompanied by reduced monoclinic distortions, supporting the excitonic mechanism of the phase transition in Ta₂NiSe₅. more

From September 29 to October 2, 2025, researchers from MPI-FKF and Peking University came together to continue their successful collaboration in condensed matter science. more
