“…40 Such obstacle-induced MIPS of active Brownian particles (ABPs) occurs at concentrations below the threshold value for MIPS in the bulk. 41 Collisions and pushes between particles cause collective rotation of the aggregate around the obstacle.

“…Are the consequences similar to the case of one obstacle being put in a bath of spherical ABPs? 41 Will the obstacle stimulate the aggregation of APs and will the APs orbit the obstacle collectively and form a sustained vortex? To answer these questions, we study, using two-dimensional simulations, a simple system composed of one circular obstacle and a bunch of APs.…”
Filaments driven by bound motor proteins and chains of self-propelled colloidal particles are typical example active polymers (APs). Due to deformability, APs exhibit very rich dynamic behaviors and collective assembling...

We study the absorption process of self-propelled particles into a finite-size dense porous medium, which is mimicked by an obstacle array. We find that, dependent on the competition of the...
The study of active systems, especially in the presence of a chemical background field, is garnering significant attention. Traditionally, the self-propelled velocity of active colloids was assumed to be constant,...
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
