Making collective phenomena visible
24 Nov 2025
Researchers at LMU and the MCQST Cluster of Excellence are developing methods for the direct observation of novel many-body systems.
In the world of quantum physics, many particles collectively often behave quite differently than would be expected from the properties of the individual units. The properties of these quantum many-body systems are strongly dependent on the range of the interactions between the particles. When such interactions occur not only between immediate neighbors, but extend over multiple sites, this can give rise to unusual collective phenomena or exotic states of matter – such as systems with special structures or bonded pairs of particles that should actually repel each other.
