摘要
活力物质是一类典型的非平衡态体系,已成为软凝聚态物理新近发展的一个重要研究方向.活力物质由微驱动粒子组成,驱动力独立地施加在体系中的每个粒子上.文章概述了作者平时研究中所关注的一些活力物质系统中出现的十分有意义的现象,着重介绍了活力物质系统的构成,以及活力物质的气液态、铁磁态、向列相态和凝胶状态中涌现出的非平衡结构及其特殊的动力学行为.
Active matter is a typical non-equilibrium system, which has become an important developing field in soft condensed matter physics. It is composed of micro-driven particles, where driving forces are applied on every particle independently. In this introductory article, we give a brief account of some specific active matter systems, where interesting phenomena are observed or predicted. We describe the structure, behavior and special dynamics of various active states, such as active liquid-gas, ferromagnetic, nematic, and gel states.
