Clustering and pattern formation in chemorepulsive active colloids
Benno Liebchen, Davide Marenduzzo, Ignacio Pagonabarraga +1
We demonstrate that migration away from self-produced chemicals (chemorepulsion) generates a generic route to clustering and pattern formation among self-propelled colloids. The cl…
Hydrodynamic oscillations and variable swimming speed in squirmers close to repulsive walls
Juho S. Lintuvuori, Aidan T. Brown, Kevin Stratford +1
We present a lattice Boltzmann study of the hydrodynamics of a fully resolved squirmer, radius R, confined in a slab of fluid between two no-slip walls. We show that the coupling b…
Light-induced self-assembly of active rectification devices
J. Stenhammar, R. Wittkowski, D. Marenduzzo +1
Self-propelled colloidal objects, such as motile bacteria or synthetic microswimmers, have microscopically irreversible individual dynamics - a feature they share with all living s…
Active Model H: Scalar Active Matter in a Momentum-Conserving Fluid
Adriano Tiribocchi, Raphael Wittkowski, Davide Marenduzzo +1
We present a continuum theory of self-propelled particles, without alignment interactions, in a momentum-conserving solvent. To address phase separation we introduce a scalar conce…
Field-controlled columnar and planar patterning of cholesteric colloids
Giuseppe D'Adamo, D. Marenduzzo, C. Micheletti +1
We study how dispersions of colloidal particles in a cholesteric liquid crystal behave under a time-dependent electric field. By controlling the amplitude and shape of the applied…
Topological Patterns in Two-dimensional Gel Electrophoresis of DNA Knots
Davide Michieletto, Davide Marenduzzo, Enzo Orlandini
Gel electrophoresis is a powerful experimental method to probe the topology of DNA and other biopolymers. While there is a large body of experimental work which allows us to accura…
A minimal physical model captures the shapes of crawling cells
E. Tjhung, A. Tiribocchi, D. Marenduzzo +1
Cell motility in higher organisms (eukaryotes) is crucial to biological functions ranging from wound healing to immune response, and also implicated in diseases such as cancer. For…
Motility-induced phase separation and coarsening in active matter
Giuseppe Gonnella, Davide Marenduzzo, Antonio Suma +1
Active systems, or active matter, are self-driven systems which live, or function, far from equilibrium - a paradigmatic example which we focus on here is provided by a suspension…
