Event details

In the study of the flow of concentrated suspensions and other 'crowded' soft matter systems, a concept that has recently excited much speculation and even a certain amount of science is so-called 'jamming'--the conversion of a liquid into a solid by application of stress. I shall discuss various experiments on jamming in colloids, demonstrating in particular an unexpected 'self-filtration' effect in concentrated hard-sphere suspensions, hopefully convincing you that this is a consequence of 'jamming'. There may also be time for a historical digression on the charming idea that jamming may explain the entire universe.

This is a weekly series of informal talks given primarily by members of the soft condensed matter and statistical mechanics groups, but is also open to members of other groups and external visitors. The aim of the series is to promote discussion and learning of various topics at a level suitable to the broad background of the group. Everyone is welcome to attend..
