Experiments on structure formation in complex continua — •Ingo Rehberg, Christof Krülle, Reinhard Richter, and Wolfgang Schöpf — Universität Bayreuth

We compare experiments with with respect to their pattern forming properties. In particular we investigate the dynamics of gelified liquid crytals (1) under the influence of an electric field, magnetic fluids driven by magnetic fields (2) and granular matter fluidized by vibration(3,4).
