This is a hands on course about the computation of electronic properties of molecules and solids using the density functional theory (DFT). The goal is to learn how to use a DFT code such as Quantum Espresso (QE) and produce reliable results. Students pick a material of their choice and study during the course of the semester its various properties using a DFT code. They report their methods and findings to the rest of the class at the end of the semester.
