CONCEPTS IN 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 oneelectron band theory in the presence of perturbation effective Hamiltonian theory elementary excitations and the various types of collective elementary excitation excitons spin waves and phonons the Fermi liquid ferromagnetic spin waves antiferromagnetic spin waves and the theory of broken symmetryThe book can be used in conjunction with a survey course in solid state physics or as the basis of a first graduatelevel course It can be read by anyone who has had basic grounding in quantum mechanics
