Active Matter: a new approach to mechanobiology?
- 👤 Speaker: Julia Yeomans (University of Oxford)
- 📅 Date & Time: Thursday 03 November 2022, 14:00 - 15:00
- 📍 Venue: Details of video conferencing will be distributed nearer the time.
Abstract
Active materials such as bacteria, molecular motors and self-propelled colloids are Nature’s engines. They extract energy from their surroundings at a single particle level and use this to do work. Active matter is becoming an increasingly popular area of research because it provides a testing ground for the ideas of non-equilibrium statistical physics, because of its relevance to the collective behaviour of living creatures, from cells to starlings, and because of its potential in designing nanomachines.
Dense active matter shows mesoscale turbulence, the emergence of chaotic flow structures characterised by high vorticity and self-propelled topological defects. I will discuss the physics of defects in active materials and describe examples where the concepts of active matter are being used to describe biological processes.
Series This talk is part of the Theory of Condensed Matter series.
