A Mathematical foundations

After successful participation, students are able to:
1. understand the implications of Schrödinger's equation and how to describe states with wave functions
2. solve Schrödinger's equation for one-dimensional problems and interpret the solution
3. apply the bra-ket formalism
4. solve the hydrogen atom and other basic problem in three-dimensions
5. explain the concept of spin and the Stern-Gerlach experiment
6. solve problems that involve two quantum states
7. solve problems using approximate methods
8. understand the concept of density matrices and quantum entanglement

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.

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 also 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 source 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.

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 both exam period directly following the lecture period and subject to the condition that the student passes the mid-term of

• obtaining 60% of the total points of the problem sets.
• The bonus will not be applied to the second exam period, if the exam was attempted and not passed in the first exam period.
