ACTIVE AND PASSIVE LIQUID CRYSTALS
We have a long-standing interest in the hydrodynamics of liquid crystals. Research over the past few years has included:
More recently we have been studying the hydrodynamic equations of active nematics, systems that produce their own energy. These equations are thought to be relevant to the motion of bacterial suspensions and solutions of molecular motors, and to the flocking and swarming behaviour observed across length scales from birds to bacteria. There are many open questions: identifying the correct continuum theory for a given active system; how to relate hydrodynamic and microscopic parameters; understanding the rheological behaviour of the active fluids.
