Spatiotemporal control of structure and dynamics in a polar active fluid
Saptorshi Ghosh, Chaitanya Joshi, Aparna Baskaran +1
We apply optimal control theory to a model of a polar active fluid (the Toner-Tu model), with the objective of driving the system into particular emergent dynamical behaviors or pr…
Surfing, sweeping, and assembly of particles by a moving liquid crystal phase boundary
Tom Shneer, Jocelyn Ochoa, Alauna C. Wheeler +5
Non-equilibrium transport of particles embedded in a liquid crystal host can, by cooling through a phase transition, be exploited to create a remarkable variety of structures inclu…
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…
Effect of confinement on the mechanics of a swelling hydrogel bead
Chaitanya Joshi, Mathew Q. Giso, Jean-François Louf +2
We recast the problem of hydrogel swelling under physical constraints as an energy optimization problem. We apply this approach to compute equilibrium shapes of hydrogel spheres co…
Morpho -- A programmable environment for shape optimization and shapeshifting problems
Chaitanya Joshi, Daniel Goldstein, Cole Wennerholm +6
An emerging theme across many domains of science and engineering is materials that change shape, often dramatically. Determining their structure involves solving a shape optimizati…
Data-driven discovery of active nematic hydrodynamics
Chaitanya Joshi, Sattvic Ray, Linnea Lemma +5
Two-dimensional active nematics are often modeled using phenomenological continuum theories that describe the dynamics of the nematic director and fluid velocity through partial di…
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…
Conformational switching of chiral colloidal rafts regulates raft-raft attractions and repulsions
Joia Miller, Chaitanya Joshi, Prerna Sharma +4
Membrane-mediated particle interactions depend both on the properties of the particles themselves and the membrane environment in which they are suspended. Experiments have shown t…
