Electron-Electron Interactions, Magnetism, and Superconductivity: Lecture Notes for Introduction to Solid State Physics

Lecture notes used as part of a graduate-level Introduction to Solid State Physics course at Cornell University. I attempt to unify and update the discussion of magnetism and superconductivity relative to standard textbook treatments, and include connections to recent research. A few related homework problems are attached at the end.
