Periodic orbits, pair nucleation, and unbinding of active nematic defects on cones
Farzan Vafa, David R. Nelson, Amin Doostmohammadi
Geometric confinement and topological constraints present promising means of controlling active materials. By combining analytical arguments derived from the Born-Oppenheimer appro…

Active topological defect absorption by a curvature singularity
Farzan Vafa, David R. Nelson, Amin Doostmohammadi
Using the Born-Oppenheimer approximation, we present a general description of topological defects dynamics in -atic materials on curved surfaces, and simplify it in the case of…

Statics and diffusive dynamics of surfaces driven by -atic topological defects
Farzan Vafa, L. Mahadevan
Inspired by epithelial morphogenesis, we consider a minimal model for the shaping of a surface driven by -atic topological defects. We show that a positive (negative) defect can…
