Two glassy states of 'sticky hard spheres'

We have studied a system of hard spheres with short-range attraction using colloid-polymer mixtures. The glass transition line was found to be re-entrant. Dynamic light scattering measurements suggest that there are two qualitatively different glassy states. One is driven by repulsion (caging), the other by attraction (bonding). Mode coupling theory and simulations also agree with this picture.
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..
