''Granular matter'' is encountered everywhere in our surroundings (sand, salt, rice, powders, ...) and in industrial processes. Despite this, the modelling of the statics and the dynamics of this form of matter remains, until today, a challenge. In this seminar, I will try to give a flavour of some recent models which have been proposed to describe the flow of granular matter (''avalanches''). I will also present some predictions on the course of avalanches. Rather than enumerate (alleged) certainties, the talk will hopefully give a sense of a science which is still in the making.
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..
