The International Conference on Many Particle Spectroscopy (MPS) is a biennial event that brings together leading scientists and researchers to explore the fundamental and applied aspects of light and charged particle interactions with matter, ranging from atoms and molecules to clusters, nanoparticles, and surfaces. MPS provides a unique forum for discussing the latest breakthroughs in the field.

Symposium on Ultrafast Molecular Dynamics with X-ray Free-Electron Lasers
June 22^nd, 2026
The Symposium on Ultrafast Molecular Dynamics with X-ray Free-Electron Lasers will take place on June 22^nd, 2026, one day before the start of MPS2026.
This satellite meeting aims to provide a focused forum for discussing the latest breakthroughs in tracking electronic and ultrafast nuclear motion using XFEL facilities. The symposium will bring together researchers working at the forefront of ultrafast science, including time-resolved X-ray spectroscopy, ultrafast diffraction, nonlinear X-ray processes, and advanced XFEL methodologies.

Attendance at the symposium will be free for all registered MPS2026 participants.

Further details on the schedule, speakers, and registration for the satellite meeting can be found here.
