Active particles confined in deformable droplets

Javier Diaz, Ignacio Pagonabarraga

AI总结:

本文采用模型研究了软约束下活性粒子与液滴变形的相互作用,揭示活性粒子能增强液滴界面形状涨落并发现两种液滴破裂机制。

摘要:

活性粒子在液滴或囊泡等软约束下呈现出引人入胜的现象,因为集体运动伴随着环境的变形而出现。采用一个模型系统地研究液滴形态和粒子分布与活性和浓度的关系,揭示出活性粒子能够引发液滴界面相对于热涨落增强的形状涨落,这与最近的实验观察相一致。可以识别出丰富的相行为,具有两种不同的液滴破裂机制。

英文摘要:

Active particles under soft confinement such as droplets or vesicles present intriguing phenomena, as collective motion emerges alongside the deformation of the environment. A model is employed to systematically investigate droplet morphology and particle distribution in relation to activity and concentration,revealing that active particles have the capacity to induce enhanced shape fluctuations in the droplet interface with respect to the thermal fluctuations, aligning with recent experimental observations. A rich phase behaviour can be identified with two different mechanism of droplet breakage.
