**COURSE DESCRIPTION:**

This is an introductory course in Solid State Physics for physics graduate students who have not previously taken an equivalent undergraduate course. It aims to develop a good understanding of the basic principles and behavior of solid state systems as well as introduce some of the theoretical tools used in understanding such systems. Topics to be discussed include the electron energy bands, quasiparticles, classical waves in a medium, quantized waves, interactions of quasiparticles, group theory, susceptibility, many-body perturbation theory, and coherence and correlation in quantum systems.

**COURSE OBJECTIVES:**

By the end of this course, the student should:

- have familiarity with some of the basic principles and theoretical approaches to understand solid state systems, their components, and the consequences of the interactions among these components.
- be able to explain how some of the physical properties of solid state materials arise from the structure and interactions of their constituents.
- be able to perform theoretical calculations and derivations of certain phenomena and the properties of specific solid state materials.
- be able to identify some of the essential, but simplifying, components of a physical system that could lead to the dominant features observable in an experiment
