    Self-organisation and complexity

    The group "Self-Organization and Complexity" explores universal properties of non-equilibrium systems with theoretical and numerical methods. Of considerable interest are methods of nonlinear dynamics like bifurcation theory and pattern formation combined with methods of statistical physics and the theory of stochastic processes.

    Structure formation in active and passive soft matter systems

    One focus of the group is the modelling of the dynamics of complex liquids and soft matter. Often, it is interface-dominated, i.e., controlled by capillarity and/or wettability. Examples include (driven) droplets on homo; and heterogeneous substrates, (active) liquid crystals and colloidal suspensions, self-propelled droplets, and multicomponent multilayer. An important objective is to understand the structure-forming interaction of the various interdependent advective and diffusive transport processes and phase transitions. The inclusion of chemical reactions and chemo-mechanical coupling naturally leads to questions related to cell locomotion, tissue growth and morphogenesis, and the motion of micro swimmers.
