Active matter encompasses systems whose individual constituents dissipate energy to exert
propelling forces on their environment. These systems exhibit dynamical phenomena with …

Active systems are driven out of equilibrium by exchanging energy and momentum with their
environment. This endows them with anomalous mechanical properties that are reviewed in …

We study the statistical properties of active Ornstein-Uhlenbeck particles (AOUPs). In this
simplest of models, the Gaussian white noise of overdamped Brownian colloids is replaced …

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 a minimal model involving two species of particles interacting via quorum-sensing
rules. Combining simulations of the microscopic model and linear stability analysis of the …

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 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 …

Inertial effects affecting both the translational and rotational dynamics are inherent to a
broad range of active systems at the macroscopic scale. Thus, there is a pivotal need for …

In passive fluid-fluid phase separation, a single interfacial tension sets both the capillary
fluctuations of the interface and the rate of Ostwald ripening. We show that these …

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 …
