Modeling density variations in two-dimensional microtubule-based active nematics
Kevin A. Mitchell, Sean Ricarte, Md Mainul Hasan Sabbir +2
A dense two-dimensional layer of aligned microtubules (MTs), powered by molecular motors, is a canonical laboratory model of active materials and a synthetic analog of biological s…
Measures of Chaotic Advection in Simulations of Active Nematics
Md Mainul Hasan Sabbir, Brandon Klein, Daniel A. Beller +1
Active nematics are non-equilibrium fluids composed of rod-like self-propelled units that collectively generate large-scale coherent flows. Here, we focus on a canonical experiment…
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…
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…
Maximally mixing active nematics
Kevin A. Mitchell, Md Mainul Hasan Sabbir, Kevin Geumhan +3
Active nematics are an important new paradigm in soft condensed matter systems. They consist of rod-like components with an internal driving force pushing them out of equilibrium.…
