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.

The International Conference on Many-Particle Spectroscopy of Atoms, Molecules, Clusters and Surfaces (MPS2026) will take place June 23–25, 2026, at the Universidad Autónoma de Madrid, Spain.
