Living and Driven Matter


Active matter, in which sustained energy transduction takes place at the scale of the constituent particles, is an important part of the physicist's answer to the question "What Is Life?" This emerging area of nonequilibrium physics has yielded insights into mechanics and statistics in living matter with a surprising recurrence of similar themes across widely disparate scales. I will present a unifying theoretical framework and make a surprising connection to some striking phenomena in sedimentation. I will then present highlights of our recent work on the (in)stability of active fluids, density fluctuations in active nematics, and flocking and collective trapping in artificial motile matter.
