Random walks in random environments constitute a pivotal area of research at the interface of probability theory, statistical physics and mathematical modelling. This field investigates stochastic ...

Imperfections in the regular atomic arrangements in crystals determine many of the properties of a material, and their diffusion is behind many microstructural changes in solids. However, imaging ...

Research in random walks and search strategies in anomalous transport addresses the fundamental processes underpinning non-standard diffusion phenomena seen in heterogeneous and complex systems.

Journal of Applied Probability, Vol. 28, No. 4 (Dec., 1991), pp. 717-726 (10 pages) Recent results on the winding angle of the ordinary two-dimensional random walk on the integer lattice are reviewed.
