项目摘要
The aim of this research project is the investigation of the collective nonequilibrium dynamics of active, i.e., self-propelled, colloidal particles on the basis of a suitable generalisation of microscopic classical dynamical density functional theory. Such active particles include interacting artificial microswimmers and swimming microorganisms. Their suspensions exhibit fascinating nonequilibrium phenomena like an almost complete loss of viscosity that are not known from suspensions of passive particles and that have not yet been explained by a microscopic theory. Due to their exceptional dynamical behaviour, suspensions of active particles have unique mechanical properties like active stiffening that allow for a number of special applications in materials science and technological processing. The results of this project are thus important not only for statistical physics, but also for technology and biology. The project will be carried out in the group of Prof. Dr. Michael E. Cates at the University of Edinburgh.
本研究项目的目的是调查积极的集体非平衡动力学,即,自推进,胶体粒子的基础上,一个适当的概括微观经典动力学密度泛函理论。这种活性颗粒包括相互作用的人工微泳者和游动微生物。它们的悬浮液表现出迷人的非平衡现象,如几乎完全失去粘性,这是被动粒子悬浮液所不知道的,也尚未被微观理论解释。由于其特殊的动力学行为,活性颗粒悬浮液具有独特的机械性能,如活性硬化,允许在材料科学和技术加工中的许多特殊应用。因此,该项目的结果不仅对统计物理学,而且对技术和生物学都很重要。该项目将在Michael E.爱丁堡大学的凯茨。
