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.

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