Active Matter and Nonequilibrium Statistical Physics

Abstract

Abstract Active matter encompasses systems whose individual constituents irreversibly dissipate energy to exert self-propelling forces on their environment. From molecular motors to bacteria, from crawling cells to large animals, active entities are found at all scales in the biological world. Over the past twenty years, scientists have managed to engineer synthetic active particles in the lab, paving the way towards smart active materials. This book gathers a pedagogical set of lecture notes that cover topics in nonequilibrium statistical mechanics and active matter. These lecture notes stem from the first summer school on Active Matter delivered at the Les Houches school of Physics. The lectures covered four main research directions: collective behaviours in active-matter systems, passive and active colloidal systems, biophysics and active matter, nonequilibrium statistical physics—from passive to active.
