Percolation Criticality of Amorphous-Amorphous Transitions in Compressed Glasses
Julien Perradin, Simona Ispas, Ricardo V. Paredes +2
The low-to-high-density transition in compressed silica glass is investigated using percolation theory. Large-scale molecular dynamics simulations of SiO glasses, with system s…
Simulation of grains in a vibrated U-tube without interstitial fluid
J. R. Darias, I. Sánchez, G. Gutiérrez +1
We present a computational study using Molecular Dynamics of the development of an accumulation of grains in one side of a two dimensional U-tube under vertical vibrations. Studyin…
On the critical behavior of two-dimensional liquid crystals
Ana Isabel Fariñas-Sánchez, Robert Botet, Bertrand Berche +1
The Lebwohl-Lasher (LL) model is the traditional model used to describe the nematic-isotropic transition of real liquid crystals. In this paper, we develop a numerical study of the…
Identification and characterization of icosahedral metallic nanowires
Samuel Peláez, Carlo Guerrero, Ricardo Paredes +2
We present and discuss an algorithm to identify and characterize the long icosahedral structures (staggered pentagonal nanowires with 1-5-1-5 atomic structure) that appear in Molec…
Statistical analysis of Ni nanowires breaking processes: a numerical simulation study
P. García-Mochales, R. Paredes, S. Peláez +1
A statistical analysis of the breaking behavior of Ni nanowires is presented. Using molecular dynamic simulations, we have determined the time evolution of both the nanowire atomic…
Granular instability in a vibrated U tube
I. Sánchez, J. R. Darias, R. Paredes +2
We study experimentally the collective motion of grains inside a U shaped tube undergoing vertical oscillations, and we develop a very simple quantitative model that captures relev…
