Autonomous route to the strange attractor: the many life stages of the chaotic bubblewheel
Michael Zhao, Saverio E. Spagnolie
A body floating atop a supersaturated fluid may accumulate bubbles along its underbelly, which can render the body rotationally unstable. But rotation can strip the surface of thes…
Morphogenesis of bacterial colonies in liquid crystalline environments
Sebastian Gonzalez La Corte, Thomas G. J. Chandler, Saverio E. Spagnolie +2
Natural bacterial habitats are often complex fluids with viscoelastic and anisotropic responses to stress; for example, they can take the form of liquid crystals (LCs), with elonga…
Active nematic response to a deformable body or boundary: elastic deformations and anchoring-induced flow
Thomas G. J. Chandler, Saverio E. Spagnolie
A body immersed in a nematic liquid crystal disturbs the fluid's preferred molecular configuration and increases its stored elastic energy. In an active nematic, the fluid componen…
Arrested development and traveling waves of active suspensions in nematic liquid crystals
Jingyi Li, Laurel Ohm, Saverio E. Spagnolie
Active particles in anisotropic, viscoelastic fluids experience competing stresses which guide their trajectories. An aligned suspension of particles can trigger a hydrodynamic ben…
Geometric dependence of curvature-induced rigidity
Hanzhang Mao, Thomas G. J. Chandler, Mark Han +1
Bending the edge of a thin elastic material promotes rigidity far from its clamped boundary. However, this curvature-induced rigidity can be overwhelmed by gravity or other externa…
Exact and approximate solutions for elastic interactions in a nematic liquid crystal
Thomas G. J. Chandler, Saverio E. Spagnolie
Anisotropic fluids appear in a diverse array of systems, from liquid-crystal displays to bacterial swarms, and are characterized by orientational order. Large colloidal particles i…
