Metastability and nucleation of bubbles in active chiral systems
Raphael Maire, Alessandro Petrini, Umberto Marini Bettolo Marconi +1
Bubbles frequently emerge in dense chiral active fluids, yet it remains unclear whether they result from an instability of the homogeneous state or from rare nucleation events with…
Effective equilibrium states in the colored-noise model for active matter II. A unified framework for phase equilibria, structure and mechanical properties
René Wittmann, Umberto Marini Bettolo Marconi, Claudio Maggi +1
Active particles driven by colored noise can be approximately mapped onto a system that obeys detailed balance. The effective interactions which can be derived for such a system al…
Effective equilibrium states in the colored-noise model for active matter I. Pairwise forces in the Fox and unified colored noise approximations
René Wittmann, Claudio Maggi, Abhinav Sharma +3
The equations of motion of active systems can be modeled in terms of Ornstein-Uhlenbeck processes (OUPs) with appropriate correlators. For further theoretical studies, these should…
Models of granular ratchets
G. Costantini, A. Puglisi, U. Marini Bettolo Marconi
We study a general model of granular Brownian ratchet consisting of an asymmetric object moving on a line and surrounded by a two-dimensional granular gas, which in turn is coupled…
