Random walks on disordered networks

  title={Random walks on disordered networks},
  author={Tomaso Aste},
Random walks are studied on disordered cellular networks in 2-and 3dimensional spaces with arbitrary curvature. The coefficients of the evolution equation are calculated in term of the structural properties of the cellular system. The effects of disorder and space-curvature on the diffusion phenomena are investigated. In disordered systems the mean square displacement displays an enhancement at short time and a lowering at long ones, with respect to the ordered case. The asymptotic expression… CONTINUE READING
