Topological delocalisation of confined 3D active nematics
Louise C. Head, Pasquale Digregorio, Davide Marenduzzo +3
Defect lines in 3D active nematic systems are intriguing topological singularities whose out-of-equilibrium dynamics remain elusive in confined settings. Here, we numerically study…
Dynamics of individual active elastic filaments with chiral self-propulsion
Chanania Steinbock, Daniel A. Beller
We study the over-damped dynamics of individual one-dimensional elastic filaments subjected to a chiral active force which propels each point of the filament at a fixed angle relat…
Chaos-generating periodic orbits of topological defects in confined active nematics
Brandon Klein, Alejandro J. Soto Franco, Md Mainul Hasan Sabbir +5
Active nematics in two dimensions stir themselves efficiently through internally generated chaotic flows, largely driven by motile disclinations. We investigate how this ten…
Gliding microtubules exhibit tunable collective rotation driven by chiral active forces
Madhuvanthi Guruprasad Athani, Nathan Prouse, Niranjan Sarpangala +11
How chirality propagates across scales remains an open question in many biological and synthetic systems. An especially clear manifestation of this propagation is found in in vitro…
Modeling active nematics via the nematic locking principle
Kevin A. Mitchell, Md Mainul Hasan Sabbir, Sean Ricarte +2
Active nematic systems consist of rod-like internally driven subunits that interact with one another to form large-scale coherent flows. They are important examples of far-from-equ…
