Interactions & forces, as a research area, focuses on the quantitative description and theoretical understanding of how physical entities influence one another via fundamental interactions and emergent effective forces. It encompasses studies of gravitational, electromagnetic, strong, and weak interactions, along with interatomic, intermolecular, and many-body forces in condensed matter, soft matter, and plasma systems. Research typically integrates field theories, potential models, and numerical simulations to characterize force laws, energy landscapes, and response functions across scales, from subatomic particles to macroscopic structures, enabling predictive models of structure, dynamics, and phase behavior in diverse physical and engineered systems.
In a paper in Physical Review Letters scientists from the department Living Matter Physics at the Max Planck Institute for Dynamics and Self-Organization (MPI-DS) propose a mechanism on how energy barriers in complex systems ...
