We discuss a reaction–diffusion model in one dimension subjected to an external driving force. Each lattice site may be occupied by at most one particle. The particles hop with rates (1±η)/2 to the right or left nearest neighbor site if it is vacant, and annihilate with rate one if it is occupied. The representation of an uncorrelated random initial state in terms of free fermions allows the calculation of multiple time‐dependent higher order correlation functions of the local density. We… 
Integrable dissipative exclusion process: Correlation functions and physical properties.
A one-parameter generalization of the symmetric simple exclusion process on a one-dimensional lattice where annihilation and creation of pairs can occur and the variance of the lattice current is computed for a finite-size system.
Effect of bias in a reaction-diffusion system in two dimensions.
A single species reaction diffusion system on a two-dimensional lattice where the particles A are biased to move towards their nearest neighbors and annihilate as they meet and the results indicate the presence of a continuous phase transition at the diffusive point.
Alternating kinetics of annihilating random walks near a free interface
The kinetics of annihilating random walks in one dimension, with the half-line x>0 initially filled, is investigated. The survival probability of the nth particle from the interface exhibits
Dynamics of the directed Ising chain
The study by Glauber of the time-dependent statistics of the Ising chain is extended to the case where each spin is influenced unequally by its nearest neighbours. The asymmetry of the dynamics
Multi-Species Screening in Anti-Ferromagnetic Pair-Annihilation Model Simulations
Pair-annihilation process models capture the behaviour of important reactions amongst fundamental physical but also chemical systems. We develop a lattice-based pairannihilation model based on
Segregation in diffusion-limited multispecies pair annihilation
The kinetics of the q species pair annihilation reaction (Ai + Aj → ∅ for 1 ≤ i < j ≤ q) in d dimensions is studied by means of analytical considerations and Monte Carlo simulations. In the long-time
The duality relation between Glauber dynamics and the diffusion - annihilation model as a similarity transformation
In this paper we address the relationship between zero temperature Glauber dynamics and the diffusion - annihilation problem in the free fermion case. We show that the well known duality
Reaction-diffusion mechanisms and quantum spin systems
We present a brief tutorial introduction into the quantum Hamiltonian formalism for stochastic many-body systems defined in terms of a master equation for their time evolution. These models describe
Stochastic non-equilibrium systems
Recent advances in the theory of non-equilibrium systems are reviewed. The emphasis is on collective behaviour, particularly non-equilibrium stochastic dynamics and steady state phase transitions.


Diffusion-annihilation in the presence of a driving field
We study the effect of an external driving force on a simple stochastic reaction-diffusion system in one dimension. In our model each lattice site may be occupied by at most one particle. These
Finite-size scaling studies of one-dimensional reaction-diffusion systems. Part I. Analytical results
We consider two single-species reaction-diffusion models on one-dimensional lattices of lengthL: the coagulation-decoagulation model and the annihilation model. For the coagulation model the system
Diffusion-annihilation and the kinetics of the Ising model in one dimension
The relationship between the one-dimensional kinetic Ising model at zero temperature and diffusion-annihilation in one dimension is studied. Explicit asymptotic results for the average domain size,
Exact solutions of anisotropic diffusion-limited reactions with coagulation and annihilation
We report exact results for one-dimensional reaction-diffusion modelsA+A→inert,A+A→A, andA+B→inert, where in the latter case like particles coagulate on encounters and move as clusters. Our study
Statics and dynamics of a diffusion-limited reaction: Anomalous kinetics, nonequilibrium self-ordering, and a dynamic transition
We solve exactly the one-dimensional diffusion-limited single-species coagulation process (A+A→A) with back reactions (A→A+A) and/or a steady input of particles (B→A). The exact solution yields not

It is argued that the spatial anisotropy introduces no appreciable changes as compared to the isotropic case, and these conjectures are supported by numerical simulations for slow reaction rates.
We look for similarity transformations which yield mappings between different one-dimensional reaction-diffusion processes. In this way results obtained for special systems can be generalized to

At higher initial exciton densities the diffusion process, and thus the reaction rate, is significantly influenced by the heat produced in the fusion reaction, and this is supported by Monte Carlo simulations.
Equivalences between stochastic systems
Time-dependent correlation functions of (unstable) particles undergoing biased or unbiased diffusion, coagulation and annihilation are studied. This is achieved by similarity transformations between
Second quantization representation for classical many-particle system
The second quantization method is applied to classical many-particle systems and is especially useful for the system in which the number of the composite molecules changes with time, e.g. the system including chemical reaction.
