Amr. Cadilhe et al., EXACT-SOLUTIONS OF LOW-DIMENSIONAL REACTION-DIFFUSION SYSTEMS, International journal of modern physics b, 11(1-2), 1997, pp. 109-114
We briefly review some common diffusion-limited reactions with emphasi
s on results for two-species reactions with anisotropic hopping. Our r
eview also covers single-species reactions. The scope is that of provi
ding reference and general discussion rather than details of methods a
nd results. Recent exact results for a two-species model with anisotro
pic hopping and with 'sticky' interaction of like particles, obtained
by a novel method which allows exact solution of certain single-specie
s and two-species reactions, are discussed.
