The course

This page describes the PDF notes (330 pages) from the fall 2013 session of the University of Toronto Condensed Matter Physics course (PHY487H1F), taught by Prof. Stephen Julian, which I took as a non-degree student.

The official course description at the time was:

Introduction to the concepts used in the modern treatment of solids. The student is assumed to be familiar with elementary quantum mechanics. Topics include: bonding in solids, crystal structures, lattice vibrations, free electron model of metals, band structure, thermal properties, magnetism and superconductivity (time permitting)

Mathematica notebooks associated with the class are also available.
