Concepts In Solids: Lectures On The Theory Of Solids

These lecture notes constitute a course on a number of central concepts of solid state physics: classification of solids; band theory; the developments in one-electron band theory with the presence of perturbation; effective Hamiltonian theory; elementary excitations and the various types of collective elementary excitation; the Fermi liquid; ferromagnetic spin waves; the antiferromagnetic spin wave; and the theory of broken symmetry.
