A di usion model based on a continuous time random walk scheme with a separable transition probability density is introduced. The probability density for long jumps is proportional to x -1- (a LÃ evy-like probability density). Even when the probability density for the walker position at time t; P(x;
The transport properties of L6vy walks are discussed in the framework of continuous time random walks (CTRW) with coupled memories. This type of walks may lead to anomalous diffusion where the mean squared displacement (r2(t))~ t ~ with ct ~ 1. We focus on the enhanced diffusion limit, ct > 1, in on
