ABSTRACT
We investigate numerically the kinetics of diffusion limited annihilation reactions in disordered binary square lattices where the reacting particles are constrained to diffuse on a concentration p of the lattice sites. We find that the asymptotic decay of the particle concentration in the percolative regime is of the form c(t,p)-cr(p)∝t-ds/2, where cr(p) is the concentration of residual particles. We recover well known results such as ds(p>=pc)=d=2 with logarithmic corrections, and ds(pc)=1.34±0.02. For p
