Instabilities, motion and deformation of active fluid droplets
Carl A. Whitfield, Rhoda J. Hawkins
We consider two minimal models of active fluid droplets that exhibit complex dynamics including steady motion, deformation, rotation and oscillating motion. First we consider a dro…
Immersed Boundary Simulations of Active Fluid Droplets
Carl A. Whitfield, Rhoda J. Hawkins
We present numerical simulations of active fluid droplets immersed in an external fluid in 2-dimensions { using} an Immersed Boundary method to simulate the fluid droplet interface…
Stress reorganisation and response in active solids
Rhoda J. Hawkins, Tanniemola B. Liverpool
We present a microscopic model of a disordered viscoelastic active solid, i.e. an active material whose long time behaviour is elastic as opposed to viscous. It is composed of fila…
A model for the orientational ordering of the plant microtubule cortical array
Rhoda J. Hawkins, Simon H. Tindemans, Bela M. Mulder
The plant microtubule cortical array is a striking feature of all growing plant cells. It consists of a more or less homogeneously distributed array of highly aligned microtubules…
Pushing off the walls: a mechanism of cell motility in confinement
R. J. Hawkins, M. Piel, G. Faure-Andre +4
We propose a novel mechanism of cell motility, which relies on the coupling of actin polymerization at the cell membrane to geometric confinement. We consider a polymerizing viscoe…
