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 derive the long-time dynamics of a tracer immersed in a one-dimensional active bath. In
contrast to previous studies, we find that the damping and noise correlations possess long …

In active matter, particles typically experience mediated interactions, which are not
constrained by Newton's third law and are therefore generically non-reciprocal. Non …

We derive the fluctuation dynamics of a probe in weak coupling with a living medium,
modeled as particles undergoing an active Ornstein-Uhlenbeck dynamics. Nondissipative …

An active bath, made of self-propelling units, is a nonequilibrium medium in which the
Einstein relation D= μk BT between the mobility μ and the diffusivity D of a tracer particle …

We show that disordered boundaries destroy bulk phase separation in scalar active systems
in dimension d< dc= 3. This is in strong contrast with the equilibrium case where boundaries …

We study the impact of quenched random potentials and torques on scalar active matter.
Microscopic simulations reveal that motility-induced phase separation is replaced in two …

We show from experiments and simulations on vibration-activated granular matter that self-
propelled polar rods in an elastic medium on a substrate turn and move towards each other …

Across a variety of spatial scales, from nanoscale biological systems to micron-scale
colloidal systems, equilibrium self-assembly is entirely dictated by—and therefore limited by …
