Optimal Control of Active Nematics [PDF]
Physical Review Letters, 2020 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 the use of two different control fields, (1) applied vorticity and (2) activity strength, to shape the dynamics of an extensile active nematic that is confined to a disk.

Driven active and passive nematics
Molecular Physics, 2015 We investigate similarities in the micro-structural dynamics between externally driven and actively driven nematics. Walls, lines of strong deformations in the director field, and topological defects are characteristic features of an active nematic ...

Active nematics with quenched disorder [PDF]
Physical Review E, 2020 We introduce a two-dimensional active nematic with quenched disorder. We write the coarse-grained hydrodynamic equations of motion for slow variables, viz. density, and orientation. Disorder strength is tuned from zero to large values. Results from the numerical solution of equations of motion as well as the calculation of two-point orientation ...

Rectified Rotational Dynamics of Mobile Inclusions in Two-Dimensional Active Nematics
Physical Review Letters, 2023 We investigate the dynamics of mobile inclusions embedded in 2D active nematics. The interplay between the inclusion shape, the boundary-induced nematic order, and the autonomous flow powers the inclusion motion.

Dynamical swirl structures powered by microswimmers in active nematics
Physica A: Statistical Mechanics and Its ApplicationsActive nematics, in their pure form, have demonstrated a plethora of dynamic and steady state behaviors, including large-scale dynamic structures, collective flows, and intricate multi-spatial temporal dynamics.
