Pattern Formation And Dynamics In Nonequilibrium Systems Pdf -

At long wavelengths, patterns are often described by a slowly varying phase (\phi(\mathbfr,t)). Defects—dislocations, disclinations, or spiral cores—are topological singularities in the phase field. Their motion governs coarsening and turbulence.

Common in fluid dynamics and magnetic films. Hexagons: Often seen in surface-tension-driven convection. pattern formation and dynamics in nonequilibrium systems pdf
