From Disks to Channels: Dynamics of Active Nematics Confined to an Annulus
Chaitanya Joshi, Zahra Zarei, Michael M. Norton +3
Confinement can be used to systematically tame turbulent dynamics occurring in active fluids. Although periodic channels are the simplest geometries to study confinement numericall…
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…
The Symmetry Basis of Pattern Formation in Reaction-Diffusion Networks
Ian Hunter, Michael M. Norton, Bolun Chen +4
In networks of nonlinear oscillators, symmetries place hard constraints on the system that can be exploited to predict universal dynamical features and steady-states, providing a r…
Machine Learning Forecasting of Active Nematics
Zhengyang Zhou, Chaitanya Joshi, Ruoshi Liu +6
Active nematics are a class of far-from-equilibrium materials characterized by local orientational order of force-generating, anisotropic constitutes. Traditional methods for predi…
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…
