| Active particles are able to self propel themselves in a systematic way by extracting and dissipating energy from their surroundings. Systems of interacting active particles describe the collective motion observed in systems as diverse as animal groups (bird flocks, fish school, etc.), bacteria, molecular motors, as well as driven granular matter. In this talk I will describe the different classes of active matter which emerge from minimal models for collective motion, which capture the essential features of this fascinating kind of matter, and discuss some results concerning their out-of-equilibrium properties. |
