Connection between Dispersive Transport and Statistics of Extreme Events
K. W. Kehr, K. P. N. Murthy, H. Ambaye
A length dependence of the effective mobility in the form of a power law, B ~ L^(1-1/alpha) is observed in dispersive transport in amorphous substances, with 0 < α< 1. We deduce th…

Diffusion Coefficients of Single and Many Particles in Lattices with Different Forms of Disorder
K. W. Kehr, T. Wichmann
A survey is given on asymptotic diffusion coefficients of particles in lattices with random transition rates. Exact and approximate results for single particles are reviewed. A rec…
