Universal and non-universal properties of transitions to spatio-temporal chaos in coupled map lattices
René Mikkelsen, Martin van Hecke, Tomas Bohr
We study the transition from laminar to chaotic behavior in deterministic chaotic coupled map lattices and in an extension of the stochastic Domany--Kinzel cellular automaton [DK].…
Sources, sinks and holes in a one-dimensional traveling wave convection experiment
Luc Pastur, Mark-Tiele Westra, Daniel Snouck +4
We study dynamical behavior of local structures, such as sources and holes, in traveling wave patterns in a very long (2 m) heated wire convection experiment. The {\em sources} und…
Coherent and Incoherent structures in systems described by the 1D CGLE: Experiments and Identification
Martin van Hecke
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…
Modulated Amplitude Waves and Defect Formation in the One-Dimensional Complex Ginzburg-Landau Equation
Lutz Brusch, Alessandro Torcini, Martin van Hecke +2
The transition from phase chaos to defect chaos in the complex Ginzburg-Landau equation (CGLE) is related to saddle-node bifurcations of modulated amplitude waves (MAWs). First, th…
