Event details

Despite it's simplicity, the hard sphere model produces complex bulk phase behaviour. I will introduce some Monte Carlo simulation methods used to study this system. In particular, I will concentrate on the Lattice Switch Monte Carlo method, which allows two different crystalline structures to be sampled in a single simulation by neatly circumventing the huge kinetic barrier between the phases. I will briefly outline the original work on the technique, and then describe the current development of the Lattice Switch method for binary hard sphere systems.
I will also look at some of the issues involved in writing parallel Monte Carlo algorithms, and summarize a new algorithm for efficient simulation of the hard sphere fluid on very large scales.

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..
