Abstract
Self-organization or dynamic self-assembly is a mechanism responsible for the formation of complex structures through multiple interactions among the microscopic components of the system. In the first part of the talk the formation of regular stripe patterns during the transfer of surfactant monolayers from water surfaces onto moving solid substrates is discussed by means of a generalized Cahn-Hilliard model. A combination of numerical simulations and continuation methods is employed to investigate stationary and time-periodic solutions of the model . The second part of the talk deals with the influence of a periodic spatial forcing on the pattern formation in Langmuir-Blodgett transfer experiments. We show that the occurring locking effects enable a control mechanism for the pattern formation process. In the one-dimensional case the parameter range in which patterns are created can be increased and the properties of occurring structures can be adjusted in a broader range. Alternatively, in two dimensions, one-dimensional stripe patterns can be destabilized, giving rise to a multitude of complex two-dimensional structures, including oblique and lattice patterns. In addition, a different control mechanism by means of a modulated transfer velocity is discussed. Our theoretical results predict that this method can also be used as an effective tool to control the pattern formation process.
