Nano-patterning of surfaces by ion sputtering: Numerical study of the anisotropic damped Kuramoto-Sivashinsky equation
E. Vitral, D. Walgraef, J. Pontes +2
Nonlinear models for pattern evolution by ion beam sputtering on a material surface present an ongoing opportunity for new numerical simulations. A numerical analysis of the evolut…
Self-Assembled Nanostructure Formation in Chemical Vapor Deposition
Daniel Walgraef
When thin films are grown on a substrate by chemical vapor deposition, the evolution of the first deposited layers may be described, on mesoscopic scales, by dynamical models of th…
Elasticity effects on the stability of growing films
Daniel Walgraef
It is shown how the combination of atomic deposition and nonlinear diffusion may lead, below a critical temperature, to the growth of nonuniform layers on a substrate. The dynamics…
Polarization coupling and pattern selection in a type-II optical parametric oscillator
Gonzalo Izus, Maxi San Miguel, Daniel Walgraef
We study the role of a direct intracavity polarization coupling in the dynamics of transverse pattern formation in type-II optical parametric oscillators. Transverse intensity patt…
Patterns arising from the interaction between scalar and vectorial instabilities in two-photon resonant Kerr cavities
Miguel Hoyuelos, Daniel Walgraef, Pere Colet +1
We study pattern formation associated with the polarization degree of freedom of the electric field amplitude in a mean field model describing a nonlinear Kerr medium close to a tw…
