Event details

This journal club talk will describe recent work of Wolynes and others [1-3] which predicts the formation of a glassy state in systems whose ordered phase consists of stripes. An example of such a phase is a lamellar liquid crystal -- and indeed the model used by Wolynes et al is virtually identical to one normally used to describe the transition to lamellae. But this is very odd because, experimentally, the lamellar phase usually forms quite easily without ever getting stuck in glassy state. So, is the prediction of the stripy glass just an artefact of the approximations, or does it have real physics in it?

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..
