The boundary naturally represents the reactants' container, but is applicable to exciton dynamics in a doped TMMC crystal. We show that a density excess, which extends into the system diffusively from the boundary, is formed in two dimensions and below. This implies a surprising result for the magnetisation near a fixed spin in the coarsening of the one-dimensional critical Ising model. The universal, dimensionally-dependent functional forms of this density excess are given by an exact solution and the field-theoretic renormalisation group.", "revisions": [ { "version": "v1", "updated": "1999-02-28T13:59:40.000Z" } ], "analyses": { "keywords": [ "reaction-diffusion processes", "boundary effects", "density excess", "general single-species reaction/coalescence process", "dimensionally-dependent functional forms" ], "tags": [ "journal article" ], "note": { "typesetting": "TeX", "pages": 0, "language": "en", "license": "arXiv", "status": "editable" } } }
