Replica symmetry breaking condition exposed by a random matrix calculation

room M128

We consider the statistical mechanics of a single classical particle placed in an N dimensional gaussian random potential. This is a model system showing several features of glassy systems. The connection between replica symmetry breaking and the complexity of stationary points and minima is revealed in this model by random matrix methods.
