Glass transition in models with controlled frustration.
A class of models with self-generated disorder and controlled frustration is studied. Between the trivial case, where frustration is not present at all, and the limit case, where frustration is present over every length scale, a region with local frustration is found where glassy dynamics appears. We suggest that in this region, the mean field model might undergo a p -spin like transition, and increasing the range of frustration, a crossover from a 1 -step replica symmetry breaking to a continuous one might be observed.
