  • Speaker: Carlos Rascon (University of Edinburgh)
  • Location: Room 2511,

Event details

The talk will consist of two parts. The first (and longer) one aims to be a basic introduction to polydispersity in condensed-matter systems: what is polydispersity?, why does it exist?, what are the consequences?, how are the phase diagrams modified?. The second part will focus on a simple theoretical description of these systems and, in particular, on the peculiar Landau expansion of the free energy at the critical point (at a mean-field level). As one could expect, the second part of the talk will contain formulae (not very long though).

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..
