We investigate with a range of models and techniques the physics of life. From bacteria swimming in complex geometries, to birds moving in concert.
A simple pile of sands contains a nearly endless number of collective states, patterns and nonequilibrium transitions. We study driven and freely cooling systems as a paradigmatic example of nonequilibrium physics.
Liquid crystals are today ubiquitous in the display technology, but they exhibit fascinating physics. We explore the interface between hydrodynamics, topological defects and phase transitions in nematic, smectic and cholesteric phases.
