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…
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…
