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…
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…
Thermal convection in mono-disperse and bi-disperse granular gases: A simulation study
Daniela Paolotti, Alain Barrat, Umberto Marini Bettolo Marconi +1
We present results of a simulation study of inelastic hard-disks vibrated in a vertical container. An Event-Driven Molecular Dynamics method is developed for studying the onset of…
