Complex systems as a research area focuses on studying systems composed of many interacting components whose collective behavior exhibits nonlinearity, emergence, adaptation, and self-organization. It integrates methods from statistical physics, dynamical systems, information theory, network science, and computational modeling to characterize structure–dynamics relationships across domains such as biology, ecology, social systems, and technological networks. Research emphasizes multiscale interactions, feedback loops, critical phenomena, robustness, and phase transitions, often using agent-based models, coupled differential equations, or stochastic processes to understand how macroscopic patterns arise from microscopic rules and how these systems respond to perturbations or control interventions.
A crowd or a flock of birds have different characteristics from those of atoms in a material, but when it comes to collective movement, the differences matter less than we might think. We can try to predict the behavior of ...

In a new study, scientists have investigated the pervasive low-rank hypothesis in complex systems, demonstrating that despite high-dimensional nonlinear dynamics, many real networks exhibit rapidly decreasing singular values, ...
Scientists studying two different configurations of bilayer graphene—the two-dimensional (2D), atom-thin form of carbon—have detected electronic and optical interlayer resonances. In these resonant states, electrons bounce ...
