Introduction to mathematical physics, fall 2013
Basic measure theory and analysis. Introductory courses to quantum mechanics or functional analysis are useful, but not necessary.
Weeks 36-42 and 44-50, Monday 14-16 and Thursday 14-16 in room C124. Exercises on Mondays, 16-18 in room CK111.
- Suggestions for topics of the final exam project are now available below. After you have finished your report, please send it to the lecturer, preferably by e-mail as a PDF attachment (you can also leave it in my pigeon hole in the mail room). I will contact you after the grading is done and we can then agree about the time of the oral exam.
- Problem sheets and lecture notes can be downloaded from below.
The main aim of the course is to present mathematical background for quantum mechanics, in particular, to explain how the time-dependent Schrödinger equation can be understood as an evolution equation on the Hilbert space of square integrable functions.
Contents: Schrödinger equation with various potentials and boundary conditions, Wigner function, unbounded operators, self-adjointness, basics of Fourier-analysis and of distribution theory, tensor product spaces, multi-particle systems and their creation operator formalism

"Final exam" = projects
As the final exam, you need to complete a project about a topic related to the course, and take part in an oral exam. A written summary of the project should be returned to the lecturer, and when its grading has been finished, we will meet to discuss the results. During the discussion there will be an easy oral exam. The exam consists of five questions related to the central concepts listed in the summary.
Below are some possible topics for the final exam project. After you have chosen your topic, please contact the lecturer to get more detailed instructions. Ideally, the report from the project should be 3-7 pages (certainly not more than 10) and contain at least one theorem with a proof based on results which are either proven in the lecture notes, or for which you can provide a reference, e.g., in a textbook.
- Relativistic Hamiltonians (see Section 11.5.b and Exercise 12.4.)
- Quantum particles in external magnetic fields (Section 11.5.a)
- Rotations and spin in quantum mechanics (Section 2.20.)
- Quadratic forms and semibounded operators (Proof of Theorem 10.5.)
- Fock space dynamics of lattice fermions (Section 13)
- Spectrum of the Hydrogen atom (Teschl, Chapter 10)
- Time-dependent Hamiltonians and Dyson series
- Trotter product formula and "Feynman path integrals" (Suggestions and instructions in Project8-v2.pdf .)
