Irreversible thermodynamics of Poisson processes with reaction.
A kinetic model is derived to study the successive movements of particles, described by a Poisson process, as well as their generation. The irreversible thermodynamics of this system is also studied from the kinetic model. This makes it possible to evaluate the differences between thermodynamical quantities computed exactly and up to second-order. Such differences determine the range of validit...
متن کاملField theoretic representation of a diffusion limited positive feedback reaction
We use a formalism developed in recent years to describe a reaction diffusion problem through a field theoretic representation starting from the master equation. This is accomplished using methods developed originally in Quantum Field Theory, specifically the coherent state representation of many particles. Such a field theoretic description can then be subject to Renormalization Group (RG) cal...
متن کاملField 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.
متن کاملSite mean-field theory for reaction-diffusion processes
We consider the branching and annihilating random walk A → 2A and 2A → 0 with reaction rates σ and λ, respectively, and hopping rate D, and study the phase diagram in the (λ/D, σ/D) plane. According to standard mean-field theory, this system is in an active state for all σ/D > 0, and perturbative renormalization suggests that this mean-field result is valid for d > 2; however, nonperturbative r...
