Nonequilibrium critical relaxation of structurally disordered systems in the short-time regime: Renormalization group description and computer simulation

Monte Carlo renormalization group of dilute 3D Ising dynamics

“…The description of such systems requires the development of special analytical and numerical methods. The effects produced by weak quenched disorder on critical phenomena have been studied for many years [3][4][5][6][7][8]. According to the Harris criterion [3], the disorder affects the critical behavior only if α > 0, the specific-heat exponent of the pure system, is positive.…”
