An exactly solvable lattice model for inhomogeneous interface growth

, 1996
We study the dynamics of an exactly solvable lattice model for inhomogeneous interface growth. The interface grows deterministically with constant velocity except along a defect line where the growth process is random. We obtain exact expressions for the

Singularities and Avalanches in Interface Growth with Quenched Disorder

, 1995
A simple model for an interface moving in a disordered medium is presented. The model exhibits a transition between the two universality classes of interface growth phenomena. Using this model, it is shown that the application of constraints to the local

Nothing moves a surface: vacancy mediated surface diffusion [PDF]

, 2000
We report scanning tunneling microscopy observations, which imply that all atoms in a close-packed copper surface move frequently, even at room temperature.

Flame propagation in random media

, 1994
We introduce a phase-field model to describe the dynamics of a self-sustaining propagating combustion front within a medium of randomly distributed reactants.

Line Shape Broadening in Surface Diffusion of Interacting Adsorbates with Quasielastic He Atom Scattering [PDF]

, 2007
The experimental line shape broadening observed in adsorbate diffusion on metal surfaces with increasing coverage is usually related to the nature of the adsorbate-adsorbate interaction.

Non-stochastic behavior of atomic surface diffusion on Cu(111) at all temperatures

, 2004
Atomic diffusion is usually understood as a succession of random, independent displacements of an adatom over the surface's potential energy landscape. Nevertheless, an analysis of Molecular Dynamics simulations of self-diffusion on Cu(111) demonstrates ...

Multi-surface coding simulations of the restricted solid-on-solid model in four dimensions [PDF]

, 2013
We study the Restricted Solid on Solid (RSOS) model for surface growth in spatial dimension d=4 by means of a multi-surface coding technique that allows to analyze samples to analyze samples of size up to $256^4$ in the steady state regime.

Dynamics of Ordering of Isotropic Magnets

, 1999
We study the dynamics of ordering of the nonconserved and conserved Heisenberg magnet. The dynamics consists of two parts - an irreversible dissipation into a heat bath and a reversible precession induced by a torque due to the local molecular field. For

Surfactant effect in heteroepitaxial growth. The Pb - Co/Cu(111) case

, 2001
A MonteCarlo simulations study has been performed in order to study the effect of Pb as surfactant on the initial growth stage of Co/Cu(111). The main characteristics of Co growing over Cu(111) face, i.e.

Novel diffusion mechanism on the GaAs(001) surface: the role of adatom-dimer interaction [PDF]

, 1997
Employing first principles total energy calculations we have studied the behavior of Ga and Al adatoms on the GaAs(001)-beta2 surface. The adsorption site and two relevant diffusion channels are identified.
