Active matter, which ranges from molecular motors to groups of animals, exists at different
length scales and timescales, and various computational models have been proposed to …

Locomotion and transport of microorganisms in fluids is an essential aspect of life. Search
for food, orientation toward light, spreading of off-spring, and the formation of colonies are …

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 matter systems are driven out of thermal equilibrium by a lack of generalized Stokes-
Einstein relation between injection and dissipation of energy at the microscopic scale. We …

Phase segregation is ubiquitously observed in immiscible mixtures, such as oil and water, in
which the mixing entropy is overcome by the segregation enthalpy,–. In monodispersed …

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

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

We establish the complete phase diagram of self-propelled hard disks in two spatial
dimensions from the analysis of the equation of state and the statistics of local order …

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 …

Active particles that are self-propelled by converting energy into mechanical motion
represent an expanding research realm in physics and chemistry. For micrometer-sized …
