Stability of periodic, stationary patterns in conserved systems — •F. Dietl, F. Bergmann, L. Rapp, and W. Zimmermann — Theoretische Physik I, Universität Bayreuth, 95440 Bayreuth, Germany

Pattern formation in systems with conserved fields is considered by studying an extended Cahn-Hilliard model. This model shows either a bifurcation to a stationary periodic pattern or a large scale phase separation. We investigate the stability of nonlinear, stationary periodic patterns, as well as the evolution of the nonlinear patterns, including the transition to a coarsening regime. We also describe possible applications and extensions of the model to vegetation patterns.
