Coherent and Incoherent structures in systems described by the 1D CGLE: Experiments and Identification

Much of the nontrivial dynamics of the one dimensional Complex Ginzburg-Landau Equation (CGLE) is dominated by propagating structures that are characterized by local ``twists’’ of the phase-field. I give a brief overview of the most important properties of these various structures, formulate a number of experimental challenges and address the question how such structures may be identified in experimental space-time data sets.
