B2: Feedback control of dynamical structures and transport in driven colloidal systems

Principal investigator:

Prof. Dr. Sabine Klapp

Project summary:

The present project aims at manipulating time-dependent phenomena in driven, correlated colloidal systems by closed-loop control. We focus on the control of a) oscillatory dynamics and excitations under shear and b) transport of low-dimensional colloidal systems subject to time-dependent fields. We advance control strategies with and without time delay based on particle computer simulations and Fokker-Planck equations, with the control targets being the particle’s coordinates, density fields, or global material properties such as stress. The results will be relevant in the areas of (micro)rheology, nanotribology and single-particle manipulation.
