#### Coarsening of "clouds" and dynamic scaling in a far-from-equilibrium model system

(American Physical Society, 2007-04)

A two-dimensional lattice gas of two species, driven in opposite directions by an external force, undergoes a jamming transition if the filling fraction is sufficiently high. Using Monte Carlo simulations, we investigate ...

#### 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 ...

#### Position and length operators in a theory with minimal length

(AIP Publishing, 2007-05)

Relations between the notions of fundamental and minimal lengths, and duality, in a system with minimal length uncertainty relations are examined. Self-adjoint versions of operators relevant to the problem, and their ...

#### Bound states of hydrogen atom in a theory with minimal length uncertainty relations

(AIP Publishing, 2007-05)

The following properties of bound states of hydrogen atom in a theory with noncommuting position operators are investigated: their number, multiplicities, accidental degeneracy, localization, and dependence on the values ...

#### 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 ...

#### Exact dynamics of a reaction-diffusion model with spatially alternating rates

(American Physical Society, 2005-05)

We present the exact solution for the full dynamics of a nonequilibrium spin chain and its dual reaction-diffusion model, for arbitrary initial conditions. The spin chain is driven out of equilibrium by coupling alternating ...

#### 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 ...

#### Inhomogeneous exclusion processes with extended objects: The effect of defect locations

(American Physical Society, 2007-11)

We study the effects of local inhomogeneities, i.e., slow sites of hopping rate q < 1, in a totally asymmetric simple exclusion process for particles of size l >= 1 (in units of the lattice spacing). We compare the simulation ...

#### 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 ...
