Field theory for reaction-diffusion processes with hard-core particles.
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 discuss a recent approach proposed by Park, Kim, and Park [Phys. Rev. E 62, 7642 (2000)]. As a test bench for our method, we show how to recover the equivalence between asymmetric diffusion of excluding particles and the noisy Burgers equation.
