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…
Active polar fluid flow in finite droplets
Carl A. Whitfield, Davide Marenduzzo, Raphaël Voituriez +1
We present a continuum level analytical model of a droplet of active contractile fluid consisting of filaments and motors. We calculate the steady state flows that result from a sp…
Analysis of a non local model for spontaneous cell polarisation
Vincent Calvez, Rhoda Hawkins, Nicolas Meunier +1
In this work, we investigate the dynamics of a non-local model describing spontaneous cell polarisation. It consists in a drift-diffusion equation set in the half-space, with the c…
Spontaneous contractility--mediated cortical flow generates cell migration in 3-dimensional environments
R. J. Hawkins, R. Poincloux, O. Bénichou +3
We present a generic model of cell motility generated by acto-myosin contraction of the cell cortex. We identify analytically dynamical instabilities of the cortex and show that th…
