Field-theory for reaction-diffusion processes with hard-core particles
F. van Wijland
Abstract
We show how to build up a systematic bosonic field-theory for a general reaction-diffusion process involving hard-core particles in arbitrary dimension. We criticize a recent approach proposed by Park, Kim and Park (Phys. Rev. E 62 (2000)). As a testbench for our method, we show how to recover the equivalence between asymmetric diffusion of excluding particles and the noisy Burgers equation.
