Overview of Disordered Systems and some Progress with the Replica Method
This talk will give an overview of some of the ideas that have proved useful in understanding disordered systems. It will then describe some progress in understanding the replica method in the context of the random energy model, the simplest disordered system where replica symmetry is broken. Disordered systems include materials such as glasses and spin glasses. Problems outside of physics, such as classic optimisation problems, neural networks and genealogy models, can also be considered as disordered systems and have been addressed using replicas and other techniques.
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..
