Nonlinear world of commercial photonic systems

Active materials, such as bacteria, molecular motors and self-propelled colloids, are Nature’s engines. They continuously transform chemical energy from their environment to mechanical work. Dense active matter shows mesoscale turbulence, the emergence of chaotic flow structures characterised by high vorticity and self-propelled topological defects.

The ideas of active matter are suggesting new ways of interpreting cell motility and cell division. I shall discuss recent results indicating that active topological defects may help to regulate turnover in epithelial cell layers and contribute to controlling the structure of bacterial colonies.

Julia Yeomans is Professor of Physics at the University of Oxford and Pauline Chan Fellow at St Hilda’s College. She applies techniques from theoretical and computational physics to problems in soft condensed matter and biophysics. Among her current research interests are how cells move and divide and how biofilms form. Julia is a Fellow of the Royal Society and was awarded the EPJE-de Gennes Lecture Prize.
