### Event details

The random energy model (REM) is the simplest model that shows non-trivial spin glass behaviour. It can be solved exactly using a fairly intuitive approach. In this theory club talk I will define the REM and analyse its spin glass transition. I will then relate this back to the spin glass concepts that I introduced in my previous talk. In particular, the structure of the free energy landscape, relation to replica symmetry breaking and the Sherrington-Kirkpatrick model.

The REM is related to a number of other interesting areas including; polymers in a random medium, extreme value statistics and genealogies in models of evolution.

This is a roughly weekly series of didactical blackboard talks focussing on some theoretical aspect of Condensed Matter, Biological, and Statistical Physics..
