Spontaneous symmetry breaking in active droplets provides a generic route to motility
E. Tjhung, D. Marenduzzo, M. E. Cates
We explore a generic mechanism whereby a droplet of active matter acquires motility by the spontaneous breakdown of a discrete symmetry. The model we study offers a simple represen…
Facilitated diffusion on confined DNA
G. Foffano, D. Marenduzzo, E. Orlandini
In living cells, proteins combine 3D bulk diffusion and 1D sliding along the DNA to reach a target faster. This process is known as facilitated diffusion, and we investigate its dy…
Bulk rheology and microrheology of active fluids
G. Foffano, J. S. Lintuvuori, A. N. Morozov +3
We simulate macroscopic shear experiments in active nematics and compare them with microrheology simulations where a spherical probe particle is dragged through an active fluid. In…
Phase separation and rotor self-assembly in active particle suspensions
J. Schwarz-Linek, C. Valeriani, A. Cacciuto +4
Adding a non-adsorbing polymer to passive colloids induces an attraction between the particles via the `depletion' mechanism. High enough polymer concentrations lead to phase separ…
Colloids in active fluids: Anomalous micro-rheology and negative drag
G. Foffano, J. S. Lintuvuori, K. Stratford +2
We simulate an experiment in which a colloidal probe is pulled through an active nematic fluid. We find that the drag on the particle is non-Stokesian (not proportional to its radi…
Self-Assembly and Nonlinear Dynamics of Dimeric Colloidal Rotors in Cholesterics
J. S. Lintuvuori, K. Stratford, M. E. Cates +1
We study by simulation the physics of two colloidal particles in a cholesteric liquid crystal with tangential order parameter alignment at the particle surface. The effective force…
