BAIER, G.; RAMIREZ, A.; AMARO, I.  e  MULLER, M.. Local induction of spatio-temporal chaos. Rev. mex. fis. [online]. 2005, vol.51, n.5, pp.447-451. ISSN 0035-001X.

A periodic perturbation of one excitable system causes a symmetry-breaking instability in two reversibly coupled neighbors. The result is applied to a two-dimensional extended system. Tuning of the local perturbation frequency causes a regular target pattern to switch first to circular chaotic waves and then to chaotic wave fragments. Thus a global order-disorder transition can be induced by local control in an otherwise homogeneous medium.

Palavras-chave : Spatio-temporal chaos; order-disorder transition; local control.
