A wide range of experimental systems including gliding, swarming and swimming bacteria,
in vitro motility assays, and shaken granular media are commonly described as self …

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

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 …

Activity and autonomous motion are fundamental in living and engineering systems. This
has stimulated the new field of'active matter'in recent years, which focuses on the physical …

We study a system of purely repulsive spherical self-propelled particles in the minimal setup
inducing motility-induced phase separation (MIPS). We show that, even if explicit alignment …

Studies of active matter, from molecular assemblies to animal groups, have revealed two
broad classes of behaviour: a tendency to align yields orientational order and collective …

It is known that purely repulsive self-propelled colloids can undergo bulk liquid-vapor phase
separation. In experiments and large-scale simulations, however, more complex steady …

Unlike in thermodynamic equilibrium where coexisting phases always have the same
temperature, here we show that systems comprising “active” self-propelled particles can self …

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 …

Because of its nonequilibrium character, active matter in a steady state can drive engines
that autonomously deliver work against a constant mechanical force or torque. As a generic …
