Sandpile models and random walkers on finite lattices
Yehiel Shilo, Ofer Biham
Abelian sandpile models, both deterministic, such as the Bak, Tang, Wiesenfeld (BTW) model [P. Bak, C. Tang and K. Wiesenfeld, Phys. Rev. Lett. {\bf 59}, 381 (1987)], and stochasti…
Exact results for hydrogen recombination on dust grain surfaces
Ofer Biham, Azi Lipshtat
The recombination of hydrogen in the interstellar medium, taking place on surfaces of microscopic dust grains, is an essential process in the evolution of chemical complexity in in…
Epitaxial growth of Cu on Cu(001): experiments and simulations
Itay Furman, Ofer Biham, Jiang-Kai Zuo +2
A quantitative comparison between experimental and Monte Carlo simulation results for the epitaxial growth of Cu/Cu(001) in the submonolayer regime is presented. The simulations ta…
Electromigration-Induced Flow of Islands and Voids on the Cu(001) Surface
Hanoch Mehl, Ofer Biham, Oded Millo +1
Electromigration-induced flow of islands and voids on the Cu(001) surface is studied at the atomic scale. The basic drift mechanisms are identified using a complete set of energy b…
Models for adatom diffusion on fcc(001) metal surfaces
H. Mehl, I. Furman, O. Biham +1
We present a class of models that describe self diffusion on several fcc(001) metal substrates within a common framework. The models are found to apply well for Cu(001), Ag(001), A…
Symmetries and Universality Classes in Conservative Sandpile Models
O. Biham, E. Milshtein, S. Solomon
The symmetry properties which determine the critical exponents and universality classes in conservative sandpile models are identified. This is done by introducing a set of models,…
