The Berkeley Overview of Computational Nanoscience, is designed to introduce a broad range of computational tools under a self-contained nanoHUB tool. This friendly introduction to classical, quantum, and statistical methods provides easy-to-understand interfaces to powerful codes including molecular dynamics, Monte Carlo methods, density functional theory, and quantum chemistry. The tool can be used in conjunction with the Berkeley Computational Nanoscience course lectures, also available on the nanoHUB, which introduce the techniques and present in-class demonstrations and homework assignments designed for use with the Berkeley Nanotechnology Tool Kit.
