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…
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…
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…
Modelling transcriptional silencing and its coupling to 3D genome organisation
Massimiliano Semeraro, Giuseppe Negro, Davide Marenduzzo +1
Timely up- or down-regulation of gene expression is crucial for cellular differentiation and function. While gene upregulation via transcriptional activators has been extensively i…
Work fluctuations for a confined Brownian particle: the role of initial conditions
Giovanni Battista Carollo, Massimiliano Semeraro, Giuseppe Gonnella +1
We study the large fluctuations of the work injected by the random force into a Brownian particle under the action of a confining harmonic potential. In particular, we compute anal…
