Patterns, Defects and Phase Singularities
The topic of this talk concerns understanding defect formation in spatially extended pattern-forming systems (such as Rayleigh-Benard Convection) that are far from equilibrium. We view these defects as coherent structures describable in terms of a phase order parameter. Using the Swift-Hohenberg equation as a canonical model, this talk will focus on the transition between grain boundary defects and concave-convex disclination pairs. This study is being carried out on experimental, numerical and analytical levels which will all be described. This is joint work with Joceline Lega (Arizona) and Nikola Kamburov (Pontificia Universidad Católica de Chile).
