Course prerequisites and required pre-readings
Students who would like to participate in our course should be familiar with the following topics:
- Quantum mechanics (a must)
- Statistical Mechanics
- Basic concepts and mathematical formalism of quantum mechanics (quantum states, evolution, measurements)
- Basic concepts (light-matter interaction) from quantum optics and laser physics
- Condensed-matter / solid-state physics
- Many-body physics
- The second-quantisation formalism of the BCS theory
The overview of these topics can be found in the pre-readings listed below. We strongly recommend to read them before the course.
