After successful completion of the course, students are able to

• Describe lattice vibrations of a solid via phonons
• Interpret a phonon band structure, and the role of anharmonic corrections
• Explain the symmetries of a solid and their connection to the properties of the solid
• Explain the electronic structure of a solid and its relation to the properties of the solid

• Second Quantization
• Quasi-Particle transformations (Bogoliubov-Valatin)
• Jellium model
• Electronic band structure
• Group theory

During the lecture the definitions and methods are motivated, explained and illustrated with the help of case studies. Online-tools should be used supplementary.

The first lecture will be held on Tuesday October 18th 2022, 11 am in Sem DB 03

Course material will be available via TUWEL

Oral individual exam on appointment. During estimated 30 minutes questions should be answered and different models discussed.
