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.
Matter gets weird at the quantum scale, and among the oddities is the Efimov effect, a state in which the attractive forces between three or more atoms bind them together, even as they are excited to higher energy levels, ...

Neutrinos are elementary particles that are predicted to be massless by the standard model of particle physics, yet their observed oscillations suggest that they do in fact have a mass, which is very low. A further characteristic ...
A research team led by Prof. Tian-Bao Ma from the Department of Mechanical Engineering at Tsinghua University has proposed a novel strategy to reduce friction and wear by inducing dynamic electronic density redistribution ...
