Active biological systems reside far from equilibrium, dissipating heat even in their steady
state, thus requiring an extension of conventional equilibrium thermodynamics and statistical …

Active systems on curved geometries are ubiquitous in the living world. In the presence of
curvature, orientationally ordered polar flocks are forced to be inhomogeneous, often …

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 …

We consider the effect of geometric confinement on the steady-state properties of a one-
dimensional active suspension subject to thermal noise. The random active force is modeled …

We derive a general lower bound on distributions of entropy production in interacting active
matter systems. The bound is tight in the limit that interparticle correlations are small and …

Purely repulsive active particles spontaneously undergo motility-induced phase separation
(MIPS) into condensed and dilute phases. Remarkably, the mechanical tension measured …

We study a system of non-interacting active particles, propelled by colored noises,
characterized by an activity time τ, and confined by a double-well potential. A straightforward …

A run-and-tumble particle in a one-dimensional box (infinite potential well) is studied. The
steady state is analytically solved and analyzed, revealing the emergent length scale of the …

We computationally studied the phase behavior and dynamics of binary mixtures of active
particles, where each species had distinct activities leading to distinct velocities, fast and …

The properties of an active fluid, for example, a bacterial bath or a collection of microtubules
and molecular motors, can be accessed through the dynamics of passive particle probes …
