Topological delocalisation of confined 3D active nematics
Louise C. Head, Pasquale Digregorio, Davide Marenduzzo +3
Defect lines in 3D active nematic systems are intriguing topological singularities whose out-of-equilibrium dynamics remain elusive in confined settings. Here, we numerically study…
Morphology, Polarization Patterns, Compression, and Entropy Production in Phase-Separating Active Dumbbell Systems
Lucio Mauro Carenza, Claudio Basilio Caporusso, Pasquale Digregorio +3
Polar patterns and topological defects are ubiquitous in active matter. In this paper, we study a paradigmatic polar active dumbbell system through numerical simulations, to clarif…
Arrested phase separation and chiral symmetry breaking in active dumbbells under shear
Lucio Mauro Carenza, Giuseppe Negro, Pasquale Digregorio +2
Through molecular dynamics simulations, we investigate the phase separation and aggregation dynamics of active dumbbell particles in two-dimensions subjected to shear. We find that…
Transverse Self-Propulsion Enhances the Aggregation of Active Dumbbells
Pasquale Digregorio, Daniela Moretti, Claudio Basilio Caporusso +5
We investigate a two-dimensional system of active Brownian dumbbells using molecular dynamics simulations. In this model, each dumbbell is driven by an active force oriented perpen…
Chaotic and periodical dynamics of active chiral droplets
Livio Nicola Carenza, Giuseppe Gonnella, Davide Marenduzzo +1
The interplay between the chirality of many biological molecules and the energy injected at small length-scales as the result of biological processes is at the base of the life of…
Morphology and flow patterns in highly asymmetric active emulsions
Giuseppe Negro, Livio Nicola Carenza, Pasquale Digregorio +2
We investigate numerically, by a hybrid lattice Boltzmann method, the morphology and the dynamics of an emulsion made of a polar active gel, contractile or extensile, and an isotro…
