Symmetry, Invariant Manifolds and Flow Reversals in Active Nematic Turbulence
Angel Naranjo, Rumayel Pallock, Caleb Wagner +1
We investigate the role of symmetry, exact coherent structures (ECSs), and their invariant manifolds in organizing flow reversals and turbulent dynamics in channel-confined two-dim…
Mechanochemical Topological Defects in an Active Nematic
Michael M. Norton, Piyush Grover
We propose a reaction-diffusion system that converts topological information of an active nematic into chemical signals. We show that a curvature-activated reaction dipole is suffi…
Exact coherent structures and phase space geometry of pre-turbulent 2D active nematic channel flow
Caleb G. Wagner, Michael M. Norton, Jae Sung Park +1
Confined active nematics exhibit rich dynamical behavior, including spontaneous flows, periodic defect dynamics, and chaotic `active turbulence'. Here, we study these phenomena usi…
Optimal Control of Active Nematics
Michael M. Norton, Piyush Grover, Michael F. Hagan +1
In this work we present the first systematic framework to sculpt active nematics systems, using optimal control theory and a hydrodynamic model of active nematics. We demonstrate t…
