We thank Ibercivis for the equivalent of 3 × 10^(6) CPU hours. The simulations were completed in the clusters Terminus (BIFI) and Horus (U. Extremadura). We also thank N. G. Fytas for a careful reading of the manuscript.We present a microcanonical Monte Carlo simulation of the site-diluted Potts model in three dimensions with eight internal states, partly carried out on the citizen supercomputer Ibercivis. Upon dilution, the pure model’s first-order transition becomes of the second order at a tricritical point. We compute accurately the critical exponents at the tricritical point. As expected from the Cardy-Jacobsen conjecture, they are compatible with their random field Ising model counterpart. The conclusion is further reinforced by comparison with older data for the Potts model with four states.engNumerical test of the Cardy-Jacobsen conjecture in the site-diluted Potts model in three dimensionsjournal articlehttp://doi.org/10.1103/PhysRevB.86.184428http://journals.aps.org/open access51-7353Field ising-model1st-order phase-transitionsAntiferromagnetic RP(2) modelCritical-behaviorZero-temperatureMonte-CarloEvaporation/Condensation transitionEquilibrium dropletsSystemsUniversality.Física (Física)Física-Modelos matemáticos22 Física
