Control of dynamical structures and transport in driven colloidal systems (B02)

本项目旨在发展胶体系统中动力学现象的控制策略。在即将到来的资助期内，我们将重点关注a）剪切下振荡动力学和局部结构的开环和反馈控制，B）延迟反馈力下的传输，以及c）中尺度时空动力学的反馈控制。新的方面涉及控制和热力学的相互作用，以及主动系统的控制。我们采用了一系列的方法，包括随机延迟方程，福克-普朗克方程，基于粒子的模拟和连续理论。结果将在流变学，纳米摩擦学和单粒子操纵领域的相关。

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.
