Addressing Molecular Dynamics Time-scale Issues to Study Atomic-scale 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...
Atomistic Simulations of Reliability
06 Jul 2010 | | Contributor(s):: Dragica Vasileska
Discrete impurity effects in terms of their statistical variations in number and position in the inversion and depletion region of a MOSFET, as the gate length is aggressively scaled, have recently been researched as a major cause of reliability degradation observed in intra-die and die-to-die...
Illinois MatSE485/Phys466/CSE485 - Atomic-Scale Simulation
out of 5 stars
27 Jan 2009 | | Contributor(s):: David M. Ceperley
THE OBJECTIVE is to learn and apply fundamental techniques used in (primarily classical) simulations in order to help understand and predict properties of microscopic systems in materials science, physics, chemistry, and biology. THE EMPHASIS will be on connections between the simulation results...

Mesoscopic Simulations of Nitromethane
12 Sep 2011 | | Contributor(s):: Jean-Bernard Maillet
We present recent developments on the dissipative particle model that allow simulating the physico-chemical behavior of a molecular material at the mesoscale level. Several ingredients have been added to the previous model, in particular concerning the intermolecular force field and the...
