Sažetak
An aerogel of volume fraction c is modeled on a 3D lattice using diffusion-limited cluster-cluster aggregation in cubic boxes of sizes up to 20 × 20 × 20. A set of q-state Potts variables are disposed on the nonoccupied sites and their order-disorder phase transition is studied by means of a Monte Carlo technique for q=3 and q=4. It is found that the transition changes from first to second order above a nonzero threshold value of c. A comparison is made with the case of randomly occupied sites. The possible application to recent experimental results is discussed.
