Learning and Teaching Methods
In the lecture the subjects will be explained in details, the theory will be constructed and examples and applications will be worked out. Discussion with students will be encouraged. The students will be guided through the literature.
In the exercises the students will be in small groups and the content of the exercises will be discussed together. In the exercise the learning content is deepened and understood using problem examples and calculations. Thus the students will be able to explain and apply the learned physics knowledge independently.

Description of exams and course work
There will be a written exam of 90 minutes duration. Therein the achievement of the competencies given in section learning outcome is tested exemplarily at least to the given cognition level using calculation problems and comprehension questions.
For example an assignment in the exam might be:
- Derive the Linblad equation
- Use the open quantum system formalism to solve a two state system problem
- Calculate the classical limit of a path integral formulation
- Solve the Dirac equation in a central potential
- Calculate the relativistic corrections to the hydrogen spectrum
- Calculate properties of a system of identical particles
- Use the Fock space and second quantization to calculate properties of a system of bosons or fermions
In the exam no learning aids are permitted.
Participation in the exercise classes is strongly recommended since the exercises prepare for the problems of the exam and rehearse the specific competencies.
There will be a bonus (one intermediate stepping of "0,3" to the better grade) on passed module exams (4,3 is not upgraded to 4,0). The bonus is applicable to both exam period directly following the lecture period and subject to the condition that the student passes the mid-term of of obtaining 60% of the total points of the problem sets.
The exam may be repeated at the end of the semester.
