B2: Control of dynamical structures and transport in driven colloidal systems

Principal investigator:

Prof. Dr. Sabine Klapp

Project summary:
The present project aims at developing control strategies for dynamical phenomena in colloidal systems. In the upcoming funding period we will focus on a) open-loop and feedback control of oscillatory dynamics and local structure under shear, b) transport under a time-delayed feedback force, and c) feedback control of spatiotemporal dynamics on the mesoscale. New aspects concern the interplay of control and thermodynamics, as well as control in active systems. We employ a spectrum of methods including stochastic delay equations, Fokker-Planck equations, particle-based simulations, and continuum theory. The results will be relevant in the areas of rheology, nanotribology and single-particle manipulation.
