String theory is a physical theory that unifies the known fundamental forces of nature at the quantum level. Point particles are replaced by fundamental strings. This concept has far reaching consequences, including extra dimensions, “stringy” dualities, and intricate mathematical structures. This course will cover the basic concepts and is intended to provide the foundations for further (self-)study and research projects in string theory. The course aims to be mostly self-contained and should be suitable also for students who do not necessarily have a background in physics.

- The classical bosonic string: Polyakov action, symmetries, equations of motion and their solution
- The quantised bosonic string: quantisation, spectrum and unification of forces, conformal anomaly and extra dimensions, compactification on a circle and T-duality
- Introduction to conformal field theory: basic concepts and application to string theory

- String theory touches many areas of mathematics and physics, so it does not make much sense to select specific topics as prerequisites. So there will be *no prerequisites*. However, if you have basic knowledge about any of the following topics, some of the concepts may be easier to understand for you: complex analysis (residue theorem), Fourier series, the wave equation, the harmonic oscillator, basic classical and/or quantum mechanics. No knowledge of advanced concepts of theoretical physics, such as general relativity or quantum field theory, is required.

- Two assignments, 20% each
- Written exam, 60%

*(Assessment subject to change)*

Lecture notes will be provided during the course.

- The course is mostly based on the book “Basic Concepts of String Theory” by Blumenhagen, Lust, Theisen. We will cover chapters 2-5 and, if time permits, some aspects of later chapters.

Johanna Knapp is a Lecturer in Mathematical Physics at the University of Melbourne. She got her PhD in Theoretical Physics in Vienna in 2007 and then moved to postdoc positions at the Max-Planck-Institute for Physics in Munich and the University of Tokyo. Before joining the University of Melbourne in 2017 she has held senior postdoc (comparable to Lecturer) positions at the Vienna University of Technology and the University of Vienna.
