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 new study published in Science today, JILA and NIST (National Institute of Standards and Technology) Fellow Jun Ye and his research team have taken a significant step in understanding the intricate and collective light-atom ...
