In many situations it is possible to model a system by entities that diffuse and occasionally react upon encounter. Examples include chemical reactions, electron-hole recombination, annealing of defects in crystals, interacting excitons (solitons, photoexcited states, and so on), predator-prey models, and the spreading of ideas through social intercourse. For concreteness and without loss of generality, we shall refer to the interacting entities as particles.
