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 …

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

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 …

Active systems evade the rules of equilibrium thermodynamics by constantly dissipating
energy at the level of their microscopic components. This energy flux stems from the …

Cilia and flagella are fundamental units of motion in cellular biology. These beating, hair-like
organelles share a common basic structure but maintain widely varying functions in systems …

Active matter physics is about systems in which energy is dissipated at some local level to
produce work. This is a generic situation, particularly in the living world but not only. What is …

Liquids composed of self-propelled particles have been experimentally realized using
molecular, colloidal or macroscopic constituents,,,,. These active liquids can flow …

The collective mobility of active matter (self-propelled objects that transduce energy into
mechanical work to drive their motion, most commonly through fluids) constitutes a new …

We show that the flocking transition in the Vicsek model is best understood as a liquid-gas
transition, rather than an order-disorder one. The full phase separation observed in flocking …

Because of its nonequilibrium character, active matter in a steady state can drive engines
that autonomously deliver work against a constant mechanical force or torque. As a generic …
