Spontaneous velocity alignment in Motility-induced Phase Separation
Lorenzo Caprini, Umberto Marini Bettolo Marconi, Andrea Puglisi
We study a system of purely repulsive spherical self-propelled particles in the minimal set-up inducing Motility-Induced Phase Separation (MIPS). We show that, even if explicit ali…
How a local active force modifies the structural properties of polymers
Laura Natali, Lorenzo Caprini, Fabio Cecconi
We study the dynamics of a polymer, described as a variant of a Rouse chain, driven by an active terminal monomer (head). The local active force induces a transition from a globule…
A comparative study between two models of active cluster-crystals
Lorenzo Caprini, Emilio Hernàndez-Garcìa, Cristòbal Lòpez +1
We study a system of active particles with soft repulsive interactions that lead to an active cluster-crystal phase in two dimensions. We use two different modelizations of the act…
Irreversibility and typicality: A simple analytical result for the Ehrenfest model
Marco Baldovin, Lorenzo Caprini, Angelo Vulpiani
With the aid of simple analytical computations for the Ehrenfest model, we clarify some basic features of macroscopic irreversibility. The stochastic character of the model allows…
The Entropy Production of Ornstein-Uhlenbeck Active Particles: a path integral method for correlations
Lorenzo Caprini, Umberto Marini Bettolo Marconi, Andrea Puglisi +1
By employing a path integral formulation, we obtain the entropy production rate for a system of active Ornstein-Uhlenbeck particles (AOUP) both in the presence and in the absence o…
Transport of active particles in an open-wedge channel
Lorenzo Caprini, Fabio Cecconi, Umberto Marini Bettolo Marconi
The transport of independent active Brownian particles within a two-dimensional narrow channel, modeled as an open-wedge, is studied both numerically and theoretically. We show tha…
