The second-order phase transition induced by the quenched random dilution in the 3D model

We present the numerical study the effect of quenched random dilution on the first-order phase transition in the threedimensional three-state Potts model. The conversion from first- to second-order phase transition is there obtained at a finite threshold of concentration. The critical behaviour of the disorder-induced second-order phase transition is derived by the finite-size scaling analysis of the momenta of energy and of the largest cluster obtained by Monte Carlo simulations.
