Elasticity tunes mechanical stress localization around active topological defects
Lasse Bonn, Aleksandra Ardaševa, Amin Doostmohammadi
Mechanical stresses are increasingly found to be associated with various biological functionalities. At the same time, topological defects are being identified across a diverse ran…
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…
Spontaneous Self-Constraint in Active Nematic Flows
Louise C. Head, Claire Dore, Ryan Keogh +5
Active processes drive and guide biological dynamics across scales -- from subcellular cytoskeletal remodelling, through tissue development in embryogenesis, to population-level ba…
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…
Spontaneous flows and dynamics of full-integer topological defects in polar active matter
Jonas Rønning, Julian Renaud, Amin Doostmohammadi +1
Polar active matter of self-propelled particles sustain spontaneous flows through the full-integer topological defects. We study theoretically the effect of both polar and dipolar…
