#### Learning and Teaching Methods

Lecture: black-board presentation

Open tutorial: The open tutorial provides the opportunity for solving the exercises for oneself or as a group. The open tutorial is overseen by different tutors an leaves room for further discussions and exchange with other students.

Tutorial: The tutorial is held in small groups. In the tutorial the weekly exercises are presented by the students and the tutor. They also provide room for discussions and additional explanations to the lectures.

#### Media

Blackboard or powerpoint presentation

#### Literature

D.J. GRIFFITHS, Introduction to Quantum Mechanics, Prentice Hall.

Good introductory materials.

F. SCHWABL, Quantenmechanik, Springer.

Highler level of detail and good presentation

J.L. BASDEVANT, J. DALIBARD, Quantum Mechanics, 2005.

Cleanly worked out; discusses both the mathematical basics as well as conceptual questions. Focuses allso an new experiments and applications.

R. SHANKAR, Principles of Quantum Mechanics, 2011.

Includes a mathematical description. Quite detailed.

M. LE BELLAC, Quantum Physics, 2012. Sorgfältige Darstellung, aber auf

quite high-level. Not useful as the only sorce for the first contact with Quantum Mechanics

J.J. SAKURAI, J.J. NAPOLITANO Modern Quantum Mechanics, 2010.

Good textbook which is also on a higher level.

R.P. FEYNMAN, R.B. LEIGHTON, M. SANDS, Feynman Vorlesungen über Physik III: Quantenmechanik, 1988.

Feynmans remarkable style with very detailed explanations. Not as systematic as other books.

### Module Exam

#### 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:

- set-up and solution of the Schrödinger equation for a particle in a potential and interpretation of the solutions
- interpretation of the physical consequences of a given wave function

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 the exam period directly following the lecture period (not to the exam repetition) and subject to the condition that the student passes the mid-term of obtaining 80% of the total points of the problem sets.

#### Exam Repetition

The exam may be repeated at the end of the semester.
