21. Mean Field Theory and Closing Thoughts

This lecture series constitutes a first undergraduate course in solid state physics delivered in an engaging and entertaining manner by Professor Steven H. Simon of Oxford University. Standard topics such as crystal structure, reciprocal space, free electrons, band theory, phonons, and magnetism are covered. The sequence of the lectures matches that of the book "The Oxford Solid State Basics" (OUP, 2013).
