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 …

Physical interfaces widely exist in nature and engineering. Although the formation of passive
interfaces is well elucidated, the physical principles governing active interfaces remain …

The collective motion of synthetic active colloids is an emerging area of research in soft
matter physics and is important both as a platform for fundamental studies ranging from non …

We study wetting droplets formed of active Brownian particles in contact with a repulsive
potential barrier, in a wedge geometry. Our numerical results demonstrate a transition …

While bacterial swarms can exhibit active turbulence in vacant spaces, they naturally inhabit
crowded environments. We numerically show that driving disorderly active fluids through …

The transport of active particles may occur in complex environments, in which it emerges
from the interplay between the mobility of the active components and the quenched disorder …

We show that incompressible polar active fluids can exhibit an ordered, coherently moving
phase even in the presence of quenched disorder in two dimensions. Unlike such active …

We experimentally and numerically study the flow of programmable active particles (APs)
with tunable cohesion strength through geometric constrictions. Similar to purely repulsive …

Recently it was predicted, on the basis of a lattice gas model, that scalar active matter in a
gravitational field would rise against gravity up a confining wall or inside a thin capillary—in …
