Ludwig-Maximilians-Universität München
Wintersemester 2022/23

Announcements

Sec. 4.7. about crossover theory and finite-size scaling is left for self-study (refer also to [Cardy]). On Dec 5, we will start Sec. 5.

Exam date is fixed, see below.

Organization

• Lectures: In-person teaching, start on Oct. 17, 2022. Last lecture Tuesday Feb. 07, 2023.

– Mondays: 14:20  (Theresienstr. 37, A449)
– Tuesdays: 12:00  (Theresienstr. 41, C111)

• Tutorial sessions: Benedikt Schneider (Schneider.Benedikt@physik.uni-muenchen.de), start on Oct. 25, 2022.

– Tuesdays: 16:15 - 18:00 (Theresienstr. 37, A450)

– Weekly homework will be assigned in the Monday lecture and collected one week later at the start of the lecture. The homework will be graded according to a coarse grading scheme with 0, 1 or 2 points per problem. In the tutorial session, the homework will be handed back and the solutions will be discussed.

– A bonus on the final grade (1.3 -> 1.0, 1.7 -> 1.3, 2.0 -> 1.7 etc.) will be granted to candidates who (i) earned at least 50% of all available homework points and (ii) presented at least one homework problem at the board in the tutorial session.

•  Exam (9 ETCS): Tuesday Feb 14, 2023; 12:00 - 14:00 in room C111, closed book exam but double-sided sheet of notes allowed, no electronic devices allowed, 120 minutes.

Prerequisites

• Quantum Mechanics, Solid State Theory, Statistical Physics
• Condensed Matter Many-Body Physics and Field Theory I (TMP - TA 3)
(basics of quantum field theory, correlation functions, functional integral, generating functionals, perturbation theory)
