Forces That Govern Life: On the Way to Understanding Intermolecular Interactions
20 Jul 2017 | | Contributor(s):: Lyudmila V. Slipchenko
This talk will overview our recent work on the Effective Fragment Potential (EFP) method. EFP is a model potential designed for describing non-covalent interactions. The absence of fitted parameters and a natural partitioning of the interaction energy into Coulomb, polarization, dispersion, and...

Calculating Resonances Using a Complex Absorbing Potential
out of 5 stars
13 Mar 2008 | | Contributor(s):: Robin Santra
The Siegert (or Gamow) wave function associated with a resonance state is exponentially divergent at large distances from the scattering target. A complex absorbing potential (CAP) provides a computationally simple and efficient technique for calculating the complex Siegert energy of a resonance...
Dynamics on the Nanoscale: Time-domain ab initio studies of quantum dots, carbon nanotubes and molecule-semiconductor interfaces
31 Jan 2008 | | Contributor(s):: Oleg Prezhdo
Device miniaturization requires an understanding of the dynamical response of materials on the nanometer scale. A great deal of experimental and theoretical work has been devoted to characterizing the excitation, charge, spin, and vibrational dynamics in a variety of novel materials, including...
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...
Renormalization Group Theories of Strongly Interacting Electronic Structure
20 Apr 2007 | | Contributor(s):: Garnet Chan, NCN at Northwestern University
Our work is in the area of the electronic structure and dynamics of complex processes. We engage in developing new and more powerful theoretical techniques which enable us to describe strong electronic correlation problems.Of particular theoretical interest are the construction of fast...
