Optimal Navigation in Stochastic and Disordered Gridworlds
Kévin Bilaï Biloa, Olivier Pierre-Louis
Navigation in complex and noisy environments is a key issue in diverse fields from biology to engineering. Despite extensive progress in numerical optimization methods for computin…
Dewetting of a solid monolayer
Olivier Pierre-Louis, Anna Chame, Yukio Saito
We report on the dewetting of a monolayer on a solid substrate, where mass transport occurs via surface diffusion. For a wide range of parameters, a labyrinthine pattern of bilayer…
A contiuum model for low temperature relaxation of crystal steps
O. Pierre-Louis
High and low temperature relaxation of crystal steps are described in a unified picture, using a continuum model based on a modified expression of the step free energy. Results are…
Terrace-Width Distributions and Step-Step Repulsions on Vicinal Surfaces: Symmetries, Scaling, Simplifications, Subtleties, and Schrödinger
T. L. Einstein, Howard L. Richards, Saul D. Cohen +1
For more than three decades, measurement of terrace width distributions (TWDs) of vicinal crystal surfaces have been recognized as arguably the best way to determine the dimensionl…
Oscillatory Driving of Crystal surfaces: a Route to Controlled Pattern Formation
O. Pierre-Louis, M. I. Haftel
We show that the oscillatory driving of crystal surfaces can induce pattern formation or smoothening. The driving force can be of quite different origin such as a pulsed laser beam…
Electromigration of Single-Layer Clusters
O. Pierre-Louis, T. L. Einstein
Single-layer atom or vacancy clusters in the presence of electromigration are studied theoretically assuming an isotropic medium. A variety of distinctive behaviors distinguish the…
