Chiral active matter in external potentials
Lorenzo Caprini, Hartmut Löwen, Umberto Marini Bettolo Marconi
We investigate the interplay between chirality and confinement induced by the presence of an external potential. For potentials having radial symmetry, the circular character of th…
Inhomogeneous entropy production in active crystals with point imperfections
Lorenzo Caprini, Hartmut Löwen, Umberto Marini Bettolo Marconi
The presence of defects in solids formed by active particles breaks their discrete translational symmetry. As a consequence, many of their properties become space-dependent and dif…
Entropons as collective excitations in active solids
Lorenzo Caprini, Umberto Marini Bettolo Marconi, Andrea Puglisi +1
The vibrational dynamics of solids is described by phonons constituting basic collective excitations in equilibrium crystals. Here we consider an active crystal composed of self-pr…
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…
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…
