论文摘要
我们使用连续模拟来研究摩擦对主动列表中缺陷排序的影响。即使在无摩擦系统中，+1/2缺陷也倾向于并排对齐，而对方反平行，反映其形成并与流量涡流循环的倾向。增加的摩擦增强了缺陷 - 缺陷相互作用的有效性，并且缺陷形成了动态发展，大规模，位置和定向订购的结构，可以解释为-1/2缺陷首选的六角形包装之间的竞争，以及由+1/2 Defects首选的矩形包装。
We use continuum simulations to study the impact of friction on the ordering of defects in an active nematic. Even in a frictionless system, +1/2 defects tend to align side-by-side and orient antiparallel reflecting their propensity to form, and circulate with, flow vortices. Increasing friction enhances the effectiveness of the defect-defect interactions, and defects form dynamically evolving, large scale, positionally and orientationally-ordered structures which can be explained as a competition between hexagonal packing, preferred by the -1/2 defects, and rectangular packing preferred by the +1/2 defects.
