Chimera states occur spontaneously in populations of coupled photosensitive chemical oscillators. Experiments and simulations are carried out on nonlocally coupled oscillators, with the coupling strength decreasing exponentially with distance. Chimera states with synchronized oscillators, phase waves, and phase clusters coexisting with unsynchronized oscillators are analyzed. Irregular motion o...

Motion camouflage is a type of pursuit strategy observed in nature. In this paper, we show that when a pair of autonomous agents, modeled as particles in three dimensions, engage in mutual motion camouflage, their dynamically coupled trajectories exhibit geometrically interesting structure, of possible relevance to applications such as surveillance.
