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…
Role of mass fluctuations in the diffusion of clusters of Brownian particles with activity
Daniela Moretti, Pasquale Digregorio, Giuseppe Gonnella +1
Motivated by the anomalous diffusion observed in clusters of active Brownian particles (ABPs), where the center-of-mass diffusion coefficient scales as with respec…
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…
Two-states Brownian particle in a Harmonic Potential
Giovanni Battista Carollo, Giuseppe Gonnella, Daniela Moretti +3
We study the behaviour of a Brownian particle in the overdamped regime in the presence of a harmonic potential, assuming its diffusion coefficient to randomly jump between two dist…
