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…
Dynamics of Motility-Induced clusters: coarsening beyond Ostwald ripening
Claudio B. Caporusso, Leticia F. Cugliandolo, Pasquale Digregorio +3
We study the dynamics of clusters of Active Brownian Disks generated by Motility-Induced Phase Separation, by applying an algorithm that we devised to track cluster trajectories. W…
Hydrodynamic effects on the liquid-hexatic transition of active colloids
Giuseppe Negro, Claudio Basilio Caporusso, Pasquale Digregorio +3
We study numerically the role of hydrodynamics in the liquid-hexatic transition of active colloids at intermediate activity, where motility induced phase separation (MIPS) does not…
Unified analysis of Topological Defects in 2D systems of Active and Passive disks
Pasquale Digregorio, Demian Levis, Leticia F. Cugliandolo +2
We provide a comprehensive quantitative analysis of localized and extended topological defects in the steady state of 2D passive and active repulsive Brownian disk systems. We show…
Motility-Induced Microphase and Macrophase Separation in a Two-Dimensional Active Brownian Particle System
Claudio B. Caporusso, Pasquale Digregorio, Demian Levis +2
As a result of nonequilibrium forces, purely repulsive self-propelled particles undergo macrophase separation between a dense and a dilute phase. We present a thorough study of the…
Full phase diagram of active Brownian disks: from melting to motility-induced phase separation
Pasquale Digregorio, Demian Levis, Antonio Suma +3
We establish the complete phase diagram of self-propelled hard disks in two spatial dimensions from the analysis of the equation of state and the statistics of local order paramete…
