Modelling the effect of myosin X motors on filopodia growth
Katrin Wolff, Conrad Barrett-Freeman, Martin R. Evans +2
We present a numerical simulation study of the dynamics of filopodial growth in the presence of active transport by myosin X motors. We employ both a microscopic agent-based model,…
Colloidal templating at a cholesteric - oil interface: Assembly guided by an array of disclination lines
J. S. Lintuvuori, A. C. Pawsey, K. Stratford +3
We simulate colloids (radius m) trapped at the interface between a cholesteric liquid crystal and an immiscible oil, at which the helical order (pitch p) in the bulk con…
Scalar field theory for active-particle phase separation
Raphael Wittkowski, Adriano Tiribocchi, Joakim Stenhammar +3
Recent theories predict phase separation among orientationally disordered active particles whose propulsion speed decreases rapidly enough with density. Coarse-grained models of th…
Rheology of Cubic Blue Phases
Oliver Henrich, Kevin Stratford, Peter V. Coveney +2
We study the behaviour of cubic blue phases under shear flow via lattice Boltzmann simulations. We focus on the two experimentally observed phases, Blue Phase I (BPI) and Blue Phas…
Phase behaviour of active Brownian particles: The role of dimensionality
Joakim Stenhammar, Davide Marenduzzo, Rosalind J. Allen +1
Recently, there has been much interest in activity-induced phase separations in concentrated suspensions of "active Brownian particles" (ABPs), self-propelled spherical particles w…
Intracellular facilitated diffusion: searchers, crowders and blockers
C. A. Brackley, M. E. Cates, D. Marenduzzo
In bacteria, regulatory proteins search for a specific DNA binding target via "facilitated diffusion": a series of rounds of 3D diffusion in the cytoplasm, and 1D linear diffusion…
Enhanced diffusion of tracer particles in dilute bacterial suspensions
Alexander Morozov, Davide Marenduzzo
Swimming bacteria create long-range velocity fields that stir a large volume of fluid and move around passive particles dispersed in the fluid. Recent experiments and simulations h…
A continuum theory of phase separation kinetics for active Brownian particles
Joakim Stenhammar, Adriano Tiribocchi, Rosalind J. Allen +2
Active Brownian particles (ABPs), when subject to purely repulsive interactions, are known to undergo activity-induced phase separation broadly resembling an equilibrium (attractio…
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…
Spiral and never-settling patterns in active suspensions
X. Yang, D. Marenduzzo, M. C. Marchetti
We present a combined numerical and analytical study of pattern formation in an active system where particles align, possess a density-dependent motility, and are subject to a logi…
Threading Dynamics of Ring Polymers in a Gel
D. Michieletto, D. Marenduzzo, E. Orlandini +2
We perform large scale three-dimensional molecular dynamics simulations of unlinked and unknotted ring polymers diffusing through a background gel, here a three-dimensional cubic l…
Mechanically driven growth of quasi-two dimensional microbial colonies
F. D. C. Farrell, O. Hallatschek, D. Marenduzzo +1
We study colonies of non-motile, rod-shaped bacteria growing on solid substrates. In our model, bacteria interact purely mechanically, by pushing each other away as they grow, and…
Flexoelectric switching in cholesteric blue phases
A. Tiribocchi, M. E. Cates, G. Gonnella +2
We present computer simulations of the response of a flexoelectric blue phase network, either in bulk or under confinement, to an applied field. We find a transition in the bulk be…
