ABINIT: First-Time User Guide
09 Jun 2009 | | Contributor(s):: Benjamin P Haley
This first-time user guide provides an introduction to using ABINIT on nanoHUB. We include a very brief summary of Density Functional Theory along with a tour of the Rappture interface. We discuss the default simulation (what happens if you don't change any inputs, and just hit "simulate") as...

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...
Carbon Nanotube Fracture
PDF document: nanotubes.pdf
Due to their mechanical properties, carbon nanotubes (CNTs) hold promise as nanoreinforcements in a variety of composites. As a result, numerous theoretical and...

Semi-empirical Molecular Orbital calculations.
Computational Nanoscience, Lecture 4: Geometry Optimization and Seeing What You're Doing
13 Feb 2008 | | Contributor(s):: Jeffrey C Grossman, Elif Ertekin
In this lecture, we discuss various methods for finding the ground state structure of a given system by minimizing its energy. Derivative and non-derivative methods are discussed, as well as the importance of the starting guess and how to find or generate good initial structures. We also briefly...
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...
ECE 495N F07 Homework 1 (Lectures 1-6)
17 Oct 2007 | | Contributor(s):: Saptarshi Das
25 May 2008 | | Contributor(s):: Masahiko Suenaga
Facio is a 3D-graphics program for molecular modeling and visualization of quantum chemical calculations(GAMESS and Gaussian).It is a GUI for FMO (Fragment MO) calculation. Selected features include:(1) From a PDB file, create GAMESS/FMO input with 4 mouse clicks.(2) Manual fragmentation for the...
Forces That Govern Life: On the Way to Understanding Intermolecular Interactions
19 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...
