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…
Strain stiffening due to stretching of entangled particles in random packings of granular materials
Eric Brown, Kevin A. Mitchell, Alice Nasto +2
Stress-strain relations for random packings of entangling chains under triaxial compression can exhibit strain stiffening and sustain stresses several orders-of-magnitude beyond ty…
Controlling chaos: Periodic defect braiding in active nematics confined to a cardioid
Fereshteh L. Memarian, Derek Hammar, Md Mainul Hasan Sabbir +3
This work examines self-mixing in active nematics, a class of fluids in which mobile topological defects drive chaotic flows in a system comprised of biological filaments and molec…
