Heterogeneities in amorphous systems under shear
J. -L. Barrat, Anael Lemaitre
The last decade has seen major progresses in studies of elementary mechanisms of deformation in amorphous materials. Here, we start with a review of physically-based theories of pl…
Superdiffusive, heterogeneous, and collective particle motion near the jamming transition in athermal disordered materials
Claus Heussinger, Ludovic Berthier, Jean-Louis Barrat
We use computer simulations to study the microscopic dynamics of an athermal assembly of soft particles near the fluid-to-solid, jamming transition. Borrowing tools developed to st…
On the study of local stress rearrangements during quasistatic plastic shear of a model glass: do local stress components contain enough information?
Michel Tsamados, Anne Tanguy, Fabien Leonforte +1
We present a numerical study of the mechanical response of a 2D Lennard-Jones amorphous solid under steady quasistatic and athermal shear. We focus here on the evolution of local s…
Microscopic elasticity of complex systems
J. -L. Barrat
Lecture Notes for the Erice Summer School 2005 Computer Simulations in Condensed Matter: from Materials to Chemical Biology. Perspectives in celebration of the 65th Birthday of Mik…
Diffusion of gold nanoclusters on graphite
L. J. Lewis, P. Jensen, N. Combe +1
We present a detailed molecular-dynamics study of the diffusion and coalescence of large (249-atom) gold clusters on graphite surfaces. The diffusivity of monoclusters is found to…
Kinetics of shape equilibration for two-dimensional islands
Pablo Jensen, Nicolas Combe, Hernán Larralde +3
We study the relaxation to equilibrium of two dimensional islands containing up to 20000 atoms by Kinetic Monte Carlo simulations. We find that the commonly assumed relaxation mech…
