Molecular dynamics studies of surface dynamics and dynamic heterogeneity of supercooled metallic liquid
… to the interface. We found that the in-plane dynamics near the free surface is faster than the bulk, and surprisingly, the local structure near the free surface can be even more compact. Besides, the investigation on the exchange rate of atoms shows that the out-of-plane dynamics on the free …

Atomistic simulations of elastic-plastic deformation of amorphous polymers
… of strain rates and temperatures using Molecular Dynamics. The model exhibits many experimentally observed characteristics such as an initial elastic response followed by yield then volume preserving plastic deformation. The stress response was decomposed into intra and inter molecular components …

Theories of slow dynamics: from glassy colloidal suspensions to entangled macromolecular liquids
Motivated by the intriguing slowing down of dynamics in glassy and polymeric fluids, microscopic theories for the dynamical behavior of these systems are explored. Of particular interest is the relative importance of equilibrium structure and topological constraints on system dynamics, and theories …
