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…
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…
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…
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…
