Advanced theory and computation of the properties of minerals and materials using first-principles methods. Such methods use fundamental physics and chemistry to predict and understand behavior of materials, and are complementary to experimental studies. This course will consist of three parts: (1) lectures on methods and their applications starting with fundamentals and working up to state of the art techniques; (2) discussion seminars on the development of first-principles methods and current state of the art studies from the literature; (3) computer laboratories to learn to use and develop computational, and critically analyze results of codes for computing materials properties. The emphasis will be on periodic bulk systems, but methods to study defects, surfaces, and interfaces will also be covered. Materials to be studied include those important at high pressures in geophysics and important technological materials. A range of methods based on density functional theory will be studied for solving the electronic problem. For studying finite temperature properties, molecular dynamics and Monte Carlo techniques using ab initio models and effective Hamiltonians will be included. State of the art issues will be discussed, including how to treat systems with important electron correlation and path integral methods.
This course will not be offered in subsequent years. Instructor: Cohen.
