Quantifying Spatio-Temporal Chaos in Rayleigh Bénard Convection
… different Γ's) and a transition to spiral defect chaos was observed for large Γ's. The temperature and thermal perturbation fields were inspected for Γ = 10 and large perturbations were found to be very localized and caused by small defects in the temperature field. The azimuthal average of …

A dynamical-systems approach to understanding turbulence in plane Couette flow
… to understand the dynamics of low-dimensional spatio-temporal chaos. Our research aimed to apply the theory to understanding turbulent fluid flows, which could be thought of as spatio-temporal chaos in a very-high dimensional space. The theory explains a system's dynamics in terms of the local …

A study of the effects of spatially localized time-delayed feedback schemes on spatio-temporal patterns
In typical attempts to control spatio-temporal chaos, spatially extended systems were subjected to protocols that perturbed them as a whole, often overlooking the potential stabilizing interaction between adjacent regions. We have shown that through the application of a time-delayed feedback scheme …

Dynamical systems approach to one-dimensional spatiotemporal chaos -- A cyclist's view
… systems approach to the study of weak turbulence(spatiotemporal chaos) based on the periodic orbit theory, emphasizing the role of recurrent patterns and coherent structures. After a brief review of the periodic orbit theory and its application to low-dimensional dynamics, we discuss its possible …

Complex Patterns in Extended Oscillatory Systems
… Oszillationen bzw. Wellen oder raumzeitlichem Chaos werden. Die komplexe Ginzburg-Landau Gleichung (CGLE) stellt ein universelles Modell zur Beschreibung dieser raumzeitlichen Strukturen dar. Diese Arbeit ist der theoretischen Analyse komplexer Muster gewidmet. Mittels numerischer Bifurkations- …
