Abstract
We present a two-tier symmetry-breaking model on a catalytic surface mediated by propagating transition fronts on two different scales. On the microscopic (nanoscale) level, there is a competition between two alternative surface phases biased by the local level of a diffusing species. On the microscopic scale, relative abundance of surface phases acts as a refractive variable biasing the balance between alternative states of the diffusive activator, thereby causing either global oscillations or domain oscillations and spiral waves in an extended system. The distribution of surface phases evolves on a longer time scale due to a curvature effect, exhibiting a kind of a ripening process coupled with oscillatory dynamics.
