Field-induced vacancy localization in a driven lattice gas: Scaling of steady states
(American Physical Society, 2000-01)
With the help of Monte Carlo simulations and a mean-field theory, we investigate the ordered steady-state structures resulting from the motion of a single vacancy on a periodic lattice which is filled with two species of ...
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 ...
Viability of competing field theories for the driven lattice gas
(American Physical Society, 2000-05)
It has recently been suggested that the driven lattice gas should be described by an alternate held theory in the limit of infinite drive. We review the original and the alternate field theory, invoking several well-documented ...
finger formation in a driven diffusive system
(American Physical Society, 1991-05)
A driven diffusive lattice gas is studied in a rectangular geometry: particles are fed in at one side and extracted at the other, after being swept through the system by a uniform driving field. Being periodic in the ...
