Ordering and Defect Dynamics in Passive and Active Nematopolars
Fabio Aprile, Massimiliano Semeraro, Giuseppe Gonnella
The coexistence of polar and nematic interactions, observed in a broad range of biological and synthetic active systems, gives rise to a rich phenomenology that continues to challe…
Thinning-by-spinning: shear rheology of dense chiral fluids
Lucio Mauro Carenza, Giuseppe Gonnella, Demian Levis +1
We investigate the linear and nonlinear rheology of dense chiral fluids composed of self-spinning particles under external shear. Using particle-based simulations of a two-dimensio…
Geometry and relaxation dynamics of nematic loops
F. Aprile, A. J. H. Houston, G. Gonnella +3
Disclination lines in three-dimensional nematic liquid crystals generically form closed loops whose topology is classified by homotopy theory. While this classification successfull…
Supercoiling DNA with a free end
Daniela Moretti, Giuseppe Gonnella, Antonio Suma +3
In this work, we combine coarse-grained Brownian dynamics simulations and mean-field theory to study supercoiling dynamics, as well as the steady-state profiles of twist and writhe…
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…
Phase Separation Kinetics in a Polar Active Field Model
Massimiliano Semeraro, Leticia F. Cugliandolo, Giuseppe Gonnella +1
A milestone of phase separation kinetics is the emergence of universal power laws governing the domain growth evolution. We investigate a phase-separating polar acti…
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…
