Grain boundary motion in layered phases
Denis Boyer, Jorge Viñals
We study the motion of a grain boundary that separates two sets of mutually perpendicular rolls in Rayleigh-Bénard convection above onset. The problem is treated either analyticall…
Square Patterns and Quasi-patterns in Weakly Damped Faraday Waves
Wenbin Zhang, Jorge Vinals
Pattern formation in parametric surface waves is studied in the limit of weak viscous dissipation. A set of quasi-potential equations (QPEs) is introduced that admits a closed repr…
Secondary Instabilities and Spatiotemporal Chaos in Parametric Surface Waves
Wenbin Zhang, Jorge Vinals
A two dimensional model is introduced to study pattern formation, secondary instabilities and the transition to spatiotemporal chaos (weak turbulence) in parametric surface waves.…
Spiral defect chaos in a model of Rayleigh-Benard convection
Hao-wen Xi, J. D. Gunton, Jorge Vinals
A numerical solution of a generalized Swift-Hohenberg equation in two dimensions reveals the existence of a spatio-temporal chaotic state comprised of a large number of rotating sp…
Numerical study of pattern formation following a convective instability in non-Boussinesq fluids
Hao-wen Xi, Jorge Vinals, J. D. Gunton
We present a numerical study of a model of pattern formation following a convective instability in a non-Boussinesq fluid. It is shown that many of the features observed in convect…
