Applied Math Seminar (AMS)

Self-propelled Topological Defects

Speaker: Julia Yeomans, University of Oxford

Location: TBA

Date: Friday, May 7, 2021, 2:30 p.m.

Synopsis:

 

Active materials such as bacteria, molecular motors and eukaryotic cells continuously transform chemical energy taken from their surroundings to mechanical work. Dense active matter shows mesoscale turbulence, the emergence of chaotic flow structures characterised by high vorticity and self-propelled topological defects. I shall describe the physics of active defects, discussing active microfluidics, active disclinations and examples of topological defects in biological systems.
