Introduction:

We will go through the following chapters: Chap. 2 Structure, Chap. 3 Length Scales, Review of Linear Algebra, Chap.6 Quantum Mechanics Review, Chap. 7 & 8 Model Quantum Mechanics Problem, Chap. 9 Density of states, Chap. 10 Bands, Chap. 11 Time-Dependent Perturbation Theory and Chap. 12 lnterband Transitions. We will adjust the pace of the course and materials covered according to the average level of the students. In general, we expect the students to put in significant effort to grasp the basics.
