MCW07 Electronic Level Alignment at Metal-Molecule Contacts with a GW Approach

05 Sep 2007 | Online Presentations | 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 systems, …

The basics of quantum Monte Carlo

15 Jun 2007 | Online Presentations | 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 …
