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…
Topological localisation and motility of active knots
Andrea Bonato, Davide Marenduzzo, Enzo Orlandini +1
Nonequilibrium active polymers provide a minimal framework to investigate biopolymers such as DNA and chromatin under the action of molecular motors. Here we study active ring poly…
Flow of deformable droplets: self-pinned glasses and string-like flow
Achille Quarante, Michael Chiang, Davide Marenduzzo +1
We investigate, through numerical simulations, the rheology of a dry suspension of deformable droplets under pressure-driven flow. The system exhibits two force-driven dynamical tr…
Spontaneous phase separation and pattern formation in a lyotropic nematic mixture
A. Bensabat, O. Skelton, J. Arlt +5
Lyotropic liquid crystals can display rich phase behaviour and self-organisation, yet the physical principles underlying their self-assembly into large scale patterns remains under…
Cluster size determines internal structure of transcription factories in human cells
Massimiliano Semeraro, Giuseppe Negro, Giada Forte +4
Transcription is a fundamental cellular process, and the first step of gene expression. In human cells, it depends on the binding to chromatin of various proteins, including RNA po…
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…
