Condensed Matter Physics III Electrons and Phonons in Solid State Materials Physics 422-3 - Spring quarter, 2018 Professor J. A. Sauls Lectures: TuTh: 11:00 - 12:30 Room: TBA, Tech Institute

This course is the third quarter in a graduate level course sequence on condensed matter and materials physics. This material in this quarter will be pretty self contained and focused primarily on kinetic theory, charge and heat transport by electrons and phonons in semiconductors, metals and superconductors. Thus, graduate quantum mechanics (412-1,2) and statistical mechanics (416-0) are useful preparation. The last 1/3 of the lectures will discuss the BCS theory of electron-phonon mediated superconductivity and the electromagnetic and transport properties of superconductors. Topics

• Quantized Atomic Vibrations: Theory of Phonons in Solids • Anharmonic Vibrations: Phonon-Phonon Interactions • Semi-Classical Dynamics of Electrons in Metals and Semiconductors • Electron-Phonon Scattering - Quasiparticles I • Electron-Electron Scattering - Quasiparticles II • Electron-Impurity Scattering - Electronic Diffusion • Boltzmann, Sommerfeld, and Landau’s Kinetic Theory of Electrons in Metals • Electrical and Thermal Conductivity • Electrical Transport in Weak Magnetic Fields • Thermo-Electric and Thermo-Magnetic Effects • High-Frequency Conductivity - Skin Effects • Quantum Effects at High Magnetic Fields • Phonon Propagation in Metals - Acoustic Attenuation • Electron-Phonon-Electron Interactions: Cooper Instability • BCS Theory of Superconductivity • Electromagnetic Response of Superconductors
