Self-propelled particles include both self-phoretic synthetic colloids and various
microorganisms. By continually consuming energy, they bypass the laws of equilibrium …

Osmosis is a universal phenomenon occurring in a broad variety of processes and fields. It
is the archetype of entropic forces, both trivial in its fundamental expression–the van't Hoff …

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 …

Active colloids are microscopic particles, which self-propel through viscous fluids by
converting energy extracted from their environment into directed motion. We first explain …

Active materials are characterized by continuous injection of energy at the microscopic level
and typically cannot be adequately described by equilibrium thermodynamics. Here we …

We study experimentally and numerically a (quasi-) two-dimensional colloidal suspension of
self-propelled spherical particles. The particles are carbon-coated Janus particles, which are …

Spontaneous formation of colonies of bacteria or flocks of birds are examples of self-
organization in active living matter. Here, we demonstrate a form of self-organization from …

Differently from passive Brownian particles, active particles, also known as self-propelled
Brownian particles or microswimmers and nanoswimmers, are capable of taking up energy …

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 …

Pressure is the mechanical force per unit area that a confined system exerts on its container.
In thermal equilibrium, it depends only on bulk properties—such as density and temperature …
