Dynamics of active particles with space-dependent swim velocity
Lorenzo Caprini, Umberto Marini Bettolo Marconi, René Wittmann +1
We study the dynamical properties of an active particle subject to a swimming speed explicitly depending on the particle position. The oscillating spatial profile of the swim veloc…
Correlated escape of active particles across a potential barrier
Lorenzo Caprini, Fabio Cecconi, Umberto Marini Bettolo Marconi
We study the dynamics of one-dimensional active particles confined in a double-well potential, focusing on the escape properties of the system, such as the mean escape time from a…
Excess and loss of entropy production for different levels of coarse-graining
Pierpaolo Bilotto, Lorenzo Caprini, Angelo Vulpiani
We investigate the effect of coarse-graining on the energetics properties of a system, focusing on entropy production. As a case of study, we consider a one-dimensional colloidal p…
Hydrodynamics of simple active liquids: the emergence of velocity correlations
Umberto Marini Bettolo Marconi, Andrea Puglisi, Lorenzo Caprini
We derive the Hydrodynamics for a system of N active, spherical, underdamped particles, interacting through conservative forces. At the microscopic level, we represent the evolutio…
A handy fluctuation-dissipation relation to approach generic noisy systems and chaotic dynamics
Marco Baldovin, Lorenzo Caprini, Angelo Vulpiani
We introduce a general formulation of the fluctuation-dissipation relations (FDR) holding also in far-from-equilibrium stochastic dynamics. A great advantage of this version of the…
Collective effects in confined Active Brownian Particles
Lorenzo Caprini, Claudio Maggi, Umberto Marini Bettolo Marconi
We investigate a two-dimensional system of active particles confined to a narrow annular domain. Despite the absence of explicit interactions among the velocities or the active for…
Generalized Fluctuation-Dissipation relations holding in non-equilibrium dynamics
Lorenzo Caprini
We derive generalized Fluctuation-Dissipation Relations (FDR) holding for a general stochastic dynamics that includes as subcases both equilibrium models for passive colloids and n…
