We study the emergence and dynamics of pulled fronts described by theFisher-Kolmogorov-Petrovsky-Piscounov (FKPP) equation in the microscopicreaction-diffusion process A + A <-> A$ on the lattice when only a particle isallowed per site. To this end we identify the parameter that controls thestrength of internal fluctuations in this model, namely, the number ofparticles per correlated volume. When internal fluctuations are suppressed, weexplictly see the matching between the deterministic FKPP description and themicroscopic particle model.Comment: 4 pages, 4 figures.
