CMSA Active Matter Seminar: Directed motion in active matter: Frictiotaxis and flocking

SEMINARS, CMSA EVENTS

Speaker:

Ricard Alert - Max Planck Institute for the Physics of Complex Systems

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.

This seminar will be held in person and on Zoom.
