'''Active matter''' is matter composed of a large number of self-propelled entities that consume energy to generate motion or forces. Unlike passive matter, which relaxes to equilibrium under thermal fluctuations, active matter is intrinsically out of equilibrium. Each constituent — whether a bacterium, a molecular motor, or a synthetic microswimmer — converts chemical energy into mechanical work, producing forces that drive collective motion.

The canonical example is a bacterial suspension: individual bacteria swim randomly, but at sufficient density they spontaneously organize into coherent flows, vortices, and turbulent-like structures. This transition from disordered to ordered motion is not driven by external fields but by the mutual interactions of the active particles themselves. The [[Vicsek Model|Vicsek model]] captures this phenomenology: particles with alignment interactions exhibit a flocking transition analogous to a [[Phase Transition|phase transition]].

Active matter bridges [[Self-Organization|self-organization]], [[Non-Equilibrium Thermodynamics|non-equilibrium thermodynamics]], and [[Emergent Computation|emergent computation]]. The collective dynamics of active systems can be understood as a form of computation in which the energy input at the microscopic scale is transformed into macroscopic information processing.
