MCW07 Electronic Level Alignment at Metal-Molecule Contacts with a GW Approach
out of 5 stars
05 Sep 2007 | | Contributor(s):: Jeffrey B. Neaton
Most recent theoretical studies of electron transport in single-molecule junctions rely on a Landauer approach, simplified to treat electron-electron interactions at a mean-field level within density functional theory (DFT). While this framework has proven relatively accurate for certain...
MCW07 Modeling Charging-based Switching in Molecular Transport Junctions
23 Aug 2007 | | Contributor(s):: Sina Yeganeh, , Mark Ratner
We will discuss several proposed explanations for the switching and negative differential resistance behavior seen in some molecular junctions. It is shown that a proposed polaron model is successful in predicting both hysteresis and NDR behavior, and the model is elaborated with image charge...

Tools for Atomic-Scale Modeling
Molecular Modeling and Electronic Structure Calculations
28 Apr 2017 | | Contributor(s):: George C. Schatz, Baudilio Tejerina, Shelby Hatch, Jennifer Roden
This is a purely computational project that is concerned with using the nanoHUB tool QC-Lab to create and optimize molecules, and to study their spectroscopic and structural properties. The molecules studied are generally small molecules of interest to atmospheric chemistry, however the tool can...
Molecular Workbench: An Interface to the Molecular World
25 Jun 2006 | | Contributor(s):: Charles Xie
The Molecular Workbench software is a free, open-source modeling and authoring program specifically designed for use in science education. Powered by a set of real-time molecular simulation engines that compute and visualize the motion of particles interacting through force fields, in both 2D...

12 Aug 2008 | | Contributor(s):: Baudilio Tejerina
This package allows users to study and analyze of molecular properties using various electronic structure methods.
Perspectives on Computational Quantum Chemistry
20 Dec 2007 | | Contributor(s):: Martin P. Head-Gordon
This presentation was one of 13 presentations in the one-day forum, "Excellence in Computer Simulation," which brought together a broad set of experts to reflect on the future of computational science and engineering.
The basics of quantum Monte Carlo
15 Jun 2007 | | Contributor(s):: Lucas Wagner, Jeffrey C Grossman, Jeffrey B. Neaton
Quantum Monte Carlo is a highly accurate method to approximately solve the Schrodinger equation. I explain quantum Monte Carlo in a way that should be accessible to someone who is somewhat familiar with quantum mechanics. The discussion is mostly conceptual.Lucas Wagner is a postdoctoral...
