Sommaire:

I will give an outline of the different projects I was involved in during my previous postdoc, working with Rob Jack at the University of Bath. At first glance they may not appear to have much in common, but I hope to convince you of the common threads that connect them.
I will begin by talking about measuring amorphous order in stable glasses (produced using transition path sampling) using point-to-set correlations. This makes some interesting links between structure and dynamics in glassy states. Then I will talk about optimizing the nucleation and growth of clusters in a system of sticky spheres as a model of self assembly - how can one make the biggest crystals in the shortest time possible? I will also talk about simulating the formation of gels under the influence of gravity in the same system, with the eventual aim of comparing simulated and experimental results. Finally I will discuss some early work I have been doing to cook up a model of the kind of material that could be used to produce phase-change memory, where stable ordered and amorphous states are in competition with each other allowing lots of data to be stored in a very small physical volume.
