Collective motility and its imitations: flows in the cell, active grains, chemotactic colloids

Speaker : Professor Sriram Ramaswamy


Abstract :

The collective movement of self-propelled particles is one of the widely observed wonders of nature, and opens a new frontier at the interface of statistical mechanics and the life sciences. A coarse-grained theoretical description known as active hydrodynamics, inspired by the mechanics and flow properties of liquid crystals, has been a notably successful contribution of physicists to this area. The creation of particulate systems that imitate self-propulsion, by chemical or mechanical means, has been another exciting direction. After a summary of recent results on flows in living cells, my talk will turn to these imitations of motility, including experiments on vibrated layers of bits of wire and theoretical studies of catalyst-coated particles.
