Investigating the role of 'random walks' in particle diffusion

Several recent experiments identify unusual patterns in particle diffusion, hinting at some underlying complexity in the process which physicists have yet to discover. Through new analysis published in The European Physical Journal B, Adrian Pacheco-Pozo and Igor Sokolov at Humboldt University of Berlin show how this behavior emerges through strong correlations between the positions of diffusing particles traveling along similar trajectories.
