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…
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…
Fluctuation Theorems for Heat exchanges between passive and active baths
Massimiliano Semeraro, Antonio Suma, Giuseppe Negro
In addition to providing general constraints on probability distributions, fluctuation theorems allow to infer essential information on the role played by temperature in heat excha…
Work fluctuations for a harmonically confined Active Ornstein-Uhlenbeck Particle
Massimiliano Semeraro, Giuseppe Gonnella, Antonio Suma +1
We study the active work fluctuations of an active Ornstein-Uhlenbeck particle in the presence of a confining harmonic potential. We tackle the problem analytically both for statio…
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…
