Lecture course in the Winter Semester 2022/23

String Theory


News

Registration for exercise sessions now open via the Physics Übungsgruppenverwaltungssystemportal

First lecture on October 18

Description

This course is a basic introduction to string theory. Topics to be covered include: Quantization of the bosonic string, string interactions, the superstring, space-time effective actions, string compactifications, D-branes and string dualities, AdS/CFT correspondence. (We won't do all of this.)

Prerequisites: Thorough knowledge of classical theoretical physics, including quantum mechanics and relativity as ingredients of quantum field theory. An understanding of particle physics and some mathematical background will also be useful.

Credits: This course is listed as a specialization module in the physics Master programme, and as an "Aufbaumodul" in the mathematics Master focus area "Modular forms, complex analysis, and mathematical physics".
The course will be evaluated based on a 24h take-home final exam. Tentative submission deadline: February 14, 2023 @ noon. To be admitted to the exam, you have to be registered (via the Physics Übungsgruppenverwaltungssystemportal) for the exercise sessions and submit valid solutions to at least 50% of homework problems.
We intend to upload problems sets on Mondays at noon (give or take). Submission deadline is the following Monday, at noon (sharp).
