QWalk Quantum Monte Carlo Tutorial: Tool Information Page
Each tool on nanoHUB has an information page that provides a description of the tool, related resources, and credits. For example, this page describes the Quantum Dot Lab: http://www.nanohub.org/tools/qdot
As a first step toward building that page for your tool, edit this page and fill in the sections below.

An accurate method to calculate the many body ground state of electrons
Quantum Monte Carlo methods solve the Schrodinger equation for many
electrons to high accuracy--exactly in some cases. In most implementations, it also has favorable scaling with system size, approximately the same as mean-field theories like density functional theory, although with a larger prefactor. This allows us to obtain accurate ground and excited state energies for realistic chemical systems. Quantities such as binding energies, reaction barriers, and band gaps are accurately simulated using QMC methods.
This tool is a tutorial on the most common QMC methods: Variational Monte Carlo and Diffusion Monte Carlo. It uses as a backend QWalk (www.qwalk.org), an open-source program that implements several QMC methods.
Are there any related seminars, tutorials, homework assignments, or other items on nanoHUB? Any other books or references that help explain the theory? If so, list them here:
