Stationary correlations for a far-from-equilibrium spin chain
(American Physical Society, 2002-10)
A kinetic one-dimensional Ising model on a ring evolves according to a generalization of Glauber rates, such that spins at even (odd) lattice sites experience a temperature T(e) (T(o)). Detailed balance is violated so that ...
Driven diffusive systems: How steady states depend on dynamics
(American Physical Society, 2004-06)
In contrast to equilibrium systems, nonequilibrium steady states depend explicitly on the underlying dynamics. Using Monte Carlo simulations with Metropolis, Glauber, and heat bath rates, we illustrate this expectation for ...
Strongly anisotropic roughness in surfaces driven by an oblique particle flux
(American Physical Society, 2006-05)
Using field theoretic renormalization, an MBE-type growth process with an obliquely incident influx of atoms is examined. The projection of the beam on the substrate plane selects a "parallel" direction, with rotational ...
Steady states of a nonequilibrium lattice gas
(American Physical Society, 2005-09)
We present a Monte Carlo study of a lattice gas driven out of equilibrium by a local hopping bias. Sites can be empty or occupied by one of two types of particles, which are distinguished by their response to the hopping ...
