Course overview and goals
This course focuses on the electronic properties of solids, especially quantum mechanical properties. Solid is a many-body system consisting of electrons and nuclei. Despite only two ingredients, the electrons in solid show rich states and physical properties. In this course, we learn basic concepts and theoretical methods to study the electronic states in the solid.
