There is a long-standing debate about whether glasses are mainly formed because they are very dense (e.g. for entropic reasons, such as in hard-sphere-like colloidal glasses), or because interparticle attractions favour arrest (e.g. in ''real'' glasses which are formed by cooling). Colloid-polymer mixtures encompass both areas, from ''repulsive'' to ''attractive'', and I will discuss how that, backed up with some mode-coupling theory, might help to understand what role the interparticle potential plays in glass formation.
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..
