The Sariçiçek howardite fall in Turkey: Source crater of HED meteorites on Vesta and impact risk of Vestoids
Ozan Unsalan, Peter Jenniskens, Qing-Zhu Yin +76
The Sariçiçek howardite meteorite shower consisting of 343 documented stones occurred on 2 September 2015 in Turkey and is the first documented howardite fall. Cosmogenic isotopes…
Why is so hard to grow a perfect crystal? - 2D and 3D Monte Carlo simulations
Bogdan Ranguelov, Alexander Karamanov
We focus our attention on Monte Carlo simulations of crystallization, which is one of the most important processes occurring in nature and technology of materials. Special attentio…
Step Bunching In Conserved Systems: Scaling And Universality
Bogdan Ranguelov, Vesselin Tonchev, Chaouqi Misbah
We study the step bunching process in three different 1D step flow models and obtain scaling relations for the step bunches formed in the long times limit. The first one was introd…
Diffusion Limited Aggregation with modified local rules
Bogdan Ranguelov, Desislava Goranova, Vesselin Tonchev +1
Results from a modified Diffusion Limited Aggregation (DLA) model are presented. The modifications of the classical DLA model are in the attachment to the cluster rules and in the…
Hybrid Models of Step Bunching
Diana Staneva, Bogdan Ranguelov, Vesselin Tonchev
We introduce two hybrid models of step bunching on vicinal crystal surfaces. The model equations for step velocity are constructed by the two possible exchanges of terms between th…
Self-Organization on Unstable Vicinal Surfaces with Competing Interactions
Vesselin Tonchev, Bogdan Ranguelov, Diana Staneva
Long-ranged step-step attractions destabilize the vicinal crystal surfaces. Their competition with shorter-ranged step-step repulsions results in self-organized patterns. The expon…
