Active fluids exhibit spontaneous flows with complex spatiotemporal structure, which have
been observed in bacterial suspensions, sperm cells, cytoskeletal suspensions, self …

Active colloids are self-propelled particles moving in viscous fluids by consuming fuel from
their surroundings. Here, we review the numerical and theoretical modeling of active …

Swarm robotics deals with the design, construction, and deployment of large groups of
robots that coordinate and cooperatively solve a problem or perform a task. It takes …

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 …

The soil bacterium Myxococcus xanthus lives in densely packed groups that form dynamic
three-dimensional patterns in response to environmental changes, such as droplet-like …

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 …

Active matter agents consume internal energy or extract energy from the environment for
locomotion and force generation. Already, rather generic models, such as ensembles of …

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

The human eye is bored by monotonous landscapes. We are depressed by gray skies,
unending plains under the wing of an airliner, featureless urban sprawl, geometric …

Self-assembly is a ubiquitous process in synthetic and biological systems, broadly defined
as the spontaneous organization of multiple subunits (macromolecules, particles, etc.) into …
