Computational Nanoscience, Lecture 17: Tight-Binding, and Moving Towards Density Functional Theory
5.0 out of 5 stars
24 Mar 2008 | Teaching Materials | Contributor(s): Elif Ertekin, Jeffrey C Grossman
The purpose of this lecture is to illustrate the application of the Tight-Binding method to a simple system and then to introduce the concept of Density Functional Theory. The motivation to...
Computational Nanoscience, Lecture 12: In-Class Simulation of Ising Model
This is a two part lecture in which we discuss the spin-spin correlation function for the the Ising model, correlation lengths, and critical slowing down. An in-class simulation of the 2D Ising...
