Bacterial colonies, bird flocks, and synthetic microswimmers show new classes of patterns (e.g., motile topological defects). Foundational PDF: Marchetti et al., "Hydrodynamics of Soft Active Matter" (Reviews of Modern Physics, 2013). pattern formation and dynamics in nonequilibrium systems pdf

An oscillating chemical reaction that produces striking spiral waves and target patterns. The BZ reaction is the archetype of an excitable medium. Key PDF resources include the "Oscillations and Traveling Waves in Chemical Systems" by Field & Burger.

For oscillatory media (e.g., chemical oscillations or superconductors), the CGLE describes near-threshold dynamics: [ \frac\partial A\partial t = A + (1 + i\alpha)\nabla^2 A - (1 + i\beta)|A|^2 A ] Solutions include plane waves, spiral defects, and spatiotemporal chaos. Springer

In a well-mixed chemical reactor, reactions proceed monotonically. However, in the BZ reaction, nonlinear feedback loops (autocatalysis) drive the system into oscillatory behavior. In a spatial medium, this creates Target Patterns and Spiral Waves. These are not static structures but waves of chemical concentration propagating through the medium.
