Multi-Gaussian modes of diffusion in a quenched random medium
arXiv:1011.1992 · doi:10.1103/PhysRevE.82.041125
Abstract
We have studied a model of a random walk in a quenched random environment. In addition to featuring anomalous diffusion and localization, for special regimes of disorder parameters the particle density decomposes into multi-Gaussian structure while its cumulative distribution is normal. We explain the observed fine structure of the density and point out its significance to experiments.
