TFY4210 Kvanteteori for mangepartikkelsystem

Spring 2012


Lecturer:
Associate professor John Ove Fjærestad (office: E5-126, email: john.fjaerestad@ntnu.no, phone: 93448)

Contents:
Lagrangian and Hamiltonian formalism for classical particles and fields. Special relativity, co- and contravariant indices. Symmetries and conserved quantities. Klein-Gordon and Dirac equation. Field quantization. Perturbation expansion and Feynman diagrams. Renormalization: cutoff regularization, bare vs. dressed quantities. Nonrelativistic systems: Second-quantized representation of one- and two-particle operators. Hubbard and Heisenberg lattice models. Spin-wave theory of ferro- and antiferromagnets. Broken symmetry, Goldstone modes.

Lectures:
Tuesdays 8:15-10:00 and Thursdays 15:15-16:00 in E5-103.

Tutorials:
Thursdays 14:15-15:00 in E5-103 (starting in week 3).
In each tutorial, one or two students will present solutions to that week's exercises (doing such a presentation is a requirement for being allowed to take the final exam).

Reference group:
Grunde H. Wesenberg (grundeh@stud.ntnu.no)
Leif Kristian Tungodden (tungodde@stud.ntnu.no)

Exam:
Monday 4 June, 09.00-13.00.
You may bring:
- an approved calculator
- Rottmann: Matematisk formelsamling/Mathematische Formelsammlung
- Barnett and Cronin: Mathematical Formulae for Engineering and Science Students

Pre-exam Q&A session:
A question-and-answer session will be held sometime in the week before the exam (date and time will be announced later).

Curriculum:
The curriculum ("pensum") for the exam is defined as the material that has been covered in lectures and tutorials, plus the typed solutions to the exercises. For the lecture material one may alternatively use the following sources/notes:
- Chs. 1-5 of lecture notes by J. O. Andersen.
- Ch. 17 of "Kvantemekanikk" by P. C. Hemmer.
- Interacting relativistic quantum field theories (mostly φ4 theory): 1, 2, 3, 4, 5
- Second quantization for nonrelativistic systems
- Noninteracting electrons
- Hubbard and Heisenberg models, spin-wave theory etc.
