Langevin equations for reaction-diffusion processes
Abstract
For reaction-diffusion processes with at most bimolecular reactants, we derive well-behaved,
numerically-tractable, exact Langevin equations that govern a stochastic variable related to the
response field in field theory. Using duality relations, we show how the particle number and other
quantities of interest can be computed. Our work clarifies long-standing conceptual issues encountered
in field theoretical approaches and paves the way to systematic numerical and theoretical
analyses of reaction-diffusion problems
