The last few years have seen many developments in the study of ?frustrated? systems, such as spin glasses and random fields. In addition, the application of the

The book introduces some useful and little known techniques in statistical mechanics and field theory including multiple Legendre transforms, supersymmetry, Fou

A comprehensive account of the theory, experimental work and computer modelling of spin glasses.

Disordered magnetic systems enjoy non-trivial properties which are different and richer than those observed in their pure, non-disordered counterparts. These pr

In the eighties, a group of theoretical physicists introduced several models for certain disordered systems, called "spin glasses". These models are simple and
