Scaling laws for random walks in long-range correlated disordered media
Scaling laws for random walks in long-range correlated disordered media
We study the scaling laws of diffusion in two-dimensional media with long-range correlated disorder through exact enumeration of random walks.The disordered medium is modelled by percolation clusters with correlations decaying with the distance as a power law, r -a , generated with the improved Fourier filtering method.To characterize this type …
