Field Theory of Critical Behaviour in Driven Diffusive Systems with Quenched Disorder
We present a field theoretic renormalization group study for the critical behaviour of a uniformly driven diffusive system with quenched disorder, which is modelled by different kinds of potential barriers between sites. Due to their symmetry properties, these different realizations of the random potential barriers lead to three different models for the phase transition to transverse order and ...
متن کامل1 Critical behavior of a non - equilibrium interacting particle system driven by an oscillatory field
Firstand second-order temperature driven transitions are studied, in a lattice gas driven by an oscillatory field. The short time dynamics study provides upper and lower bounds for the first-order transition points obtained using standard simulations. The difference between upper and lower bounds is a measure for the strength of the firstorder transition and becomes negligible small for densiti...
متن کاملA Diffusive System Driven by a Battery or by a Smoothly Varying Field
We consider the steady state of a one dimensional diffusive system, such as the symmetric simple exclusion process (SSEP) on a ring, driven by a battery at the origin or by a smoothly varying field along the ring. The battery appears as the limiting case of a smoothly varying field, when the field becomes a delta function at the origin. We find that in the scaling limit the long range pair corr...
متن کاملCritical Behavior of Target Space Mean Field Theory
Recently, the free energy of the target space mean field (TSMF) matrix model has been calculated in the low temperature phase, order-by-order in a low temperature expansion. The TSMF model is a matrix model whose discrete target space has an infinite coordination number, and whose free energy assumes a universal form, corresponding to baby universes joined into a tree. Here the free energy is s...
متن کاملRenormalized field theory and particle density profile in driven diffusive systems with open boundaries.
Renormalized field theory and particle density profile in driven diffusive systems with open boundaries Abstract We investigate the density profile in a driven diffusive system caused by a plane particle source perpendicular to the driving force. Focussing on the case of critical bulk density ¯ c we use a field theoretic renormalization group approach to calculate the density c(z) as a function...
