SUMMARY:Directed motion in active matter: Frictiotaxis and flocking
DESCRIPTION:Active Matter Seminar \nSpeaker: Ricard Alert\, Max Planck Institute for the Physics of Complex Systems \nTitle: Directed motion in active matter: Frictiotaxis and flocking \nAbstract: A key feature of active matter is its ability to move directionally\, both as individual particles and collectively. I will discuss two examples of directed motion: one in cell migration\, and one in collections of self-propelled colloids. First\, I will show that cells lacking cell-substrate adhesions migrate along friction gradients. We call this phenomenon frictiotaxis\, which is a new type of cell guidance. Second\, I will present a new mechanism for flocking whereby self-propelled particles can align and move collectively despite turning away from each other.
