Spatio-temporal pattern formation with oscillatory chemical reaction and continuousphoton flux on a micrometre scale

Abstract

Over the past few decades, spontaneous pattern formation in reaction–diffusion systems hasbeen actively studied both theoretically and experimentally. In this article, we report novelphenomena that are generated beyond the framework of usual reaction–diffusion systems:(1) chemical wave propagation under the effect of a boundary, (2) convection in areaction–diffusion system, and (3) dynamical phase separation under nonequilibriumconditions caused by a focused laser. All of these phenomena are generated as aresult of cross-hierarchical interaction between macroscopic and mesoscopic scales.
