Gerard Toulouse had always been interested in the spin glass problem. In 1977, subsequent to the work I discussed in my last column (September 1988, page 9), Gerard, then at the Ecole Normale Superieure in Paris, began to discuss the problem with the powerful "Cargese" group of theoretical physicists in Paris and Rome: Cyrano de Dominicis, Giorgio Parisi and Miguel Virasoro in particular, and later Bernard Derrida, Nick Sourlas and others. Gerard was the originator of the formal theory of… 
Binomial Spin Glass.
TLDR
A fundamental noncommutativity of the thermodynamic and continuous coupling limits that leads to the presence or absence of degeneracies depending on the precise way the limits are taken is uncovered.
Frustration and Fluctuations in Systems with Quenched Disorder
As Phil Anderson noted long ago, frustration can be generally defined by measuring the fluctuations in the coupling energy across a plane boundary between two large blocks of material. Since that
