Active escape dynamics: the effect of persistence on barrier crossing
Lorenzo Caprini, Umberto Marini Bettolo Marconi, Andrea Puglisi +1
We study a system of non-interacting active particles, propelled by colored noises, characterized by an activity time , and confined by a double-well potential. A straightforwar…
Active chiral particles under confinement: surface currents and bulk accumulation phenomena
Lorenzo Caprini, Umberto Marini Bettolo Marconi
In this work, we study the stationary behavior of an assembly of independent chiral active particles under confinement by employing an extension of the active Ornstein-Uhlenbeck mo…
Active particles under confinement and effective force generation among surfaces
Lorenzo Caprini, Umberto Marini Bettolo Marconi
We consider the effect of geometric confinement on the steady-state properties of a one-dimensional active suspension subject to thermal noise. The random active force is modeled b…
Activity induced delocalization and freezing in self-propelled systems
Lorenzo Caprini, Umberto Marini Bettolo Marconi, Andrea Puglisi
We study a system of interacting active particles, propelled by colored noises, characterized by an activity time τ, and confined by a single-well anharmonic potential. We assume p…
Comment on "Entropy Production and Fluctuation Theorems for Active Matter"
L. Caprini, U. Marini Bettolo Marconi, A. Puglisi +1
This is a comment to a letter by D. Mandal, K. Klymko and M. R. DeWeese published as Phys. Rev. Lett. 119, 258001 (2017).
Cluster crystals for Brownian particles with combined soft and hard-core repulsive interactions
Lorenzo Caprini, Emilio Hernandez-Garcia, Cristobal Lopez
Particle systems interacting with a soft repulsion, at thermal equilibrium and under some circumstances, are known to form cluster crystals, i.e. periodic arrangements of particle…
Linear response and correlation of a self-propelled particle in the presence of external fields
Lorenzo Caprini, Umberto Marini Bettolo Marconi, Angelo Vulpiani
We study the non-equilibrium properties of non interacting active Ornstein-Uhlenbeck particles (AOUP) subject to an external nonuniform field using a Fokker-Planck approach with a…
