TLDR
Steady states of driven lattice gases with open boundaries are investigated, and two types of phase transitions involving nonanalytic changes in the density profiles and the particles number fluctuation spectra are encountered upon varying the feeding rate and the particle interactions.Abstract:
Steady states of driven lattice gases with open boundaries are investigated. Particles are red into the system at one edge, travel under the action of an external field, and leave the system at the opposite edge. Two types of phase transitions involving nonanalytic changes in the density profiles and the particle number fluctuation spectra are encountered upon varying the feeding rate and the particle interactions, and associated diverging length scales are identified. The principle governing the transitions is the tendency of the system to maximize the transported current.read more

Traffic and related self-driven many-particle systems

Statistical physics of vehicular traffic and some related systems
TL;DR: In this paper, a critical review of particle-hopping models of vehicular traffic is presented, focusing on the results obtained mainly from the so-called "particle hopping" models, particularly emphasizing those formulated in recent years using the language of cellular automata.

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.

Kinetic roughening phenomena, stochastic growth, directed polymers and all that. Aspects of multidisciplinary statistical mechanics
TL;DR: Kinetic interfaces form the basis of a fascinating, interdisciplinary branch of statistical mechanics as mentioned in this paper, which can be unified via an intriguing nonlinear stochastic partial differential equation whose consequences and generalizations have mobilized a sizeable community of physicists concerned with a statistical description of kinetically roughened surfaces.
