Abstract
We study the soft percolation model in three dimensions, where the connecti vity between two sites distributed randomly falls off with distance r as (1 - (r/r(0))(0))(alpha)(theta = 1,3) when r(0) is a cutoff length. For both models, the diffusivity critical exponent is shown to depend on ct, deviati ng from the universal value for the ordinary process of alpha = 0. (C) 1999 Elsevier Science B.V.
