Exact solution of the totally asymmetric simple exclusion process: Shock profiles

TLDR
In this paper, the microscopic structure of macroscopic shocks in the one-dimensional, totally asymmetric simple exclusion process is obtained exactly from the complete solution of the stationary state of a model system containing two types of particles.
Abstract
The microscopic structure of macroscopic shocks in the one-dimensional, totally asymmetric simple exclusion process is obtained exactly from the complete solution of the stationary state of a model system containing two types of particles-“first” and “second” class. This nonequilibrium steady state factorizes about any second-class particle, which implies factorization in the one-component system about the (random) shock position. It also exhibits several other interesting features, including long-range correlations in the limit of zero density of the second-class particles. The solution also shows that a finite number of second-class particles in a uniform background of first-class particles form a weakly bound state.

An exactly soluble non-equilibrium system : the asymmetric simple exclusion process

Nonequilibrium steady states of matrix-product form: a solver's guide

TL;DR: The general problem of determining the steady state of stochastic nonequilibrium systems such as those used to model biological transport and traffic flow is considered, and a unified, pedagogical account of the various means by which the statistical mechanical calculations of macroscopic physical quantities are actually performed is presented.

Statistical mechanics of driven diffusive systems

TL;DR: In this paper, the authors focus on steady states "far from equilibrium" where such schemes break down, and propose a simple non-equilibrium model, referred to as the standard model.

Exact solution of a 1d asymmetric exclusion model using a matrix formulation

TL;DR: In this paper, a new approach based on representing the weights of each configuration in the steady state as a product of noncommuting matrices is presented, and the whole solution of the fully asymmetric exclusion problem is reduced to finding two matrices and two vectors which satisfy very simple algebraic rules.

An exact solution of a one-dimensional asymmetric exclusion model with open boundaries

TL;DR: In this paper, a simple asymmetric exclusion model with open boundaries is solved exactly in one dimension by deriving a recursion relation for the steady state, which gives the closed expressions for the average occupations of all sites.

Finite-size effects and shock fluctuations in the asymmetric simple-exclusion process.

TL;DR: This work considers a system of particles on a lattice of L sites, evolving according to the asymmetric simple-exclusion process, and finds that fluctuations of the shock position about its average value grow like ${\mathit{L}}^{1/2}$ or £1/3$ depending upon whether particle-hole symmetry exists.
