Active particles contain internal degrees of freedom with the ability to take in and dissipate
energy and, in the process, execute systematic movement. Examples include all living …

In these notes we provide an introductory description of the physics of active matter, focusing
on theoretical aspects, and on some methods which are often used in the field. We discuss a …

These lecture notes are designed to provide a brief introduction into the phenomenology of
active matter and to present some of the analytical tools used to rationalize the emergent …

The study of systems with sustained energy uptake and dissipation at the scale of the
constituent particles is an area of central interest in nonequilibrium statistical physics …

This review summarizes theoretical progress in the field of active matter, placing it in the
context of recent experiments. This approach offers a unified framework for the mechanical …

The statistical mechanics and microhydrodynamics of active matter systems have been
studied intensively during the past several years, by various soft matter physicists, chemists …

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 …

Active systems are self-driven systems that live, or function, far from thermodynamic
equilibrium. A paradigmatic example is provided by a suspension of interacting self-motile …

Large-scale collective behavior in suspensions of active particles can be understood from
the balance of statistical forces emerging beyond the direct microscopic particle interactions …

Systems at equilibrium like molecular or colloidal suspensions have a well-defined thermal
energy kBT that quantifies the particles' kinetic energy and gauges how “hot” or “cold” the …
