SUMMARY:Active nematics and topological defects - Prof. Julia Yeomans\, Un
 iversity of Oxford

DESCRIPTION:Active systems\, such as the cytoskeleton and bacterial suspen
 sions\, provide their own energy and hence operate out of thermodynamic eq
 uilibrium. Continuum models describing active systems are closely related 
 to those describing liquid crystal hydrodynamics\, together with an additi
 onal ‘active’ stress term. We discuss the role of topological defects 
 in the turbulent-like flow which occurs in many dense active nematics\, an
 d relate our results to experiments on suspensions of microtubules and mol
 ecular motors.
