The emergence of collective motion in systems of active matter is a ubiquitous and intriguing phenomenon that is found in systems such as flocks of birds, motor proteins, and bacterial suspensions. These systems consist of self-driven particles, in which each unit is capable of converting stored or ambient energy into movement through a medium. The motion of each particle is not set by an external field, but is rather set by the orientation of the particle itself. Interactions between active particles or the particles and their medium, gives rise to highly correlated collective motion and orientational order. In this talk, I will overview the general principles of collective motion of active matter, and discuss several examples in both living and non-living systems. I will also discuss theoretical models which attempt to describe the unusual statistics and pattern formation of systems of active matter.
The talk is from 3-4 pm (snacks at 2:30!). Make sure to follow the Graduate Seminar Series on Facebook.
