CGL Defect Chaos and Bursts in Hexagonal Rotating non-Boussinesq Convection
Santiago Madruga, Hermann Riecke, Werner Pesch
We employ numerical computations of the full Navier-Stokes equations to investigate non-Boussinesq convection in a rotating system using water as a working fluid. We identify two r…
Near-Resonant, Steady Mode Interaction: Periodic, Quasi-Periodic and Localized Patterns
M. Higuera, H. Riecke, M. Silber
Motivated by the rich variety of complex periodic and quasi-periodic patterns found in systems such as two-frequency forced Faraday waves, we study the interaction of two spatially…
Instabilities and Spatio-Temporal Chaos in Hexagon Patterns with Rotation
Filip Sain, Hermann Riecke
The dynamics of hexagon patterns in rotating systems are investigated within the framework of modified Swift-Hohenberg equations that can be considered as simple models for rotatin…
Localized Structures in Pattern-Forming Systems
Hermann Riecke
A number of mechanisms that lead to the confinement of patterns to a small part of a translationally symmetric pattern-forming system are reviewed: nonadiabatic locking of fronts,…
