Pattern Induced by Parameter Modulation in Spatiotemporal Chaos

  • Leone Fronzoni

Abstract

We consider the effect of a parametric modulation in a system that shows electrohydrodynamic instability with spatiotemporal chaos. This instability appears when an electric field is applied to a sample of Liquid Crystals confined between two conducting plates. The pattern degenerates in to spatiotemporal chaos when the field exceeds a threshold. A suitable modulation of the electric field induces a new ordered pattern in spite of the presence of chaos. A possible interpretation of this phenomena is discussed on the basis of transient travelling waves (TTW) present in the chaotic regime.
