Nonequilibrium systems exhibit ordered patterns despite the absence of a global potential minimizing free energy. Unlike equilibrium phase transitions (governed by Boltzmann statistics), nonequilibrium patterns arise from instabilities of homogeneous states, driven by external fluxes or chemical reactions.
