Dense active systems are widespread in nature, examples range from bacterial colonies to
biological tissues. Dense clusters of active particles can be obtained by increasing the …

Within a simple model of attractive active Brownian particles, we predict flocking behavior
and challenge the widespread idea that alignment interactions are necessary to observe this …

We study how inertia affects the behavior of self-propelled particles moving through a
viscous solvent by employing the underdamped version of the active Ornstein–Uhlenbeck …

Motility-induced phase separation (MIPS), the phenomenon in which purely repulsive active
particles undergo a liquid-gas phase separation, is among the simplest and most widely …

We explore the emergence of nonequilibrium collective motion in disordered nonthermal
active matter when persistent motion and crowding effects compete, using simulations of a …

When driven by nonequilibrium fluctuations, particle systems may display phase transitions
and physical behavior with no equilibrium counterpart. We study a two-dimensional particle …

We investigate the effect of rotational inertia on the collective phenomena of underdamped
active systems and show that the increase of the moment of inertia of each particle favors …

We propose a new overarching model for self-propelled particles that flexibly generates a
full family of “descendants.” The general dynamics introduced in this paper, which we …

We perform large-scale computer simulations of an off-lattice two-dimensional model of
active particles undergoing a motility-induced phase separation (MIPS) to investigate the …

Recently, it has been discovered that systems of active Brownian particles (APB) at high
density organise their velocities into coherent domains showing large spatial structures in …
