Addressing Molecular Dynamics Timescale Issues to Study Atomicscale Friction
12 Oct 2010   Contributor(s):: Ashlie Martini
This presentation will include an introduction to several accelerated molecular dynamics methods. However, particular focus will be given to parallel replica (ParRep) dynamics in which atomistic simulations are run parallel in time to extend their total duration. The ParRep method is based on the...

Ripples and Warping of Graphene: A Theoretical Study
19 May 2010   Contributor(s):: Umesh V. Waghmare
We use firstprinciples density functional theory based analysis to understand formation of ripples in graphene and related 2D materials. For an infinite graphene, we show that ripples are linked with a low energy branch of phonons that exhibits quadratic dispersion at long wavelengths. Many...
