#### 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 ...

#### 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 ...

#### 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 ...

#### 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 ...

#### 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 ...

#### 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 ...

#### 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 ...

#### 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 ...

#### Effects of receptor clustering on ligand dissociation kinetics: Theory and simulations

(CELL PRESS, 2005-12-01)

Receptor-ligand binding is a critical first step in signal transduction and the duration of the interaction can impact signal generation. In mammalian cells, clustering of receptors may be facilitated by heterogeneous zones ...

#### 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 ...
