#### Prerequisites

- None

#### Corequisites

- Advanced Quantum Theory IV (MATH4061) OR Particle Theory (PHYS4181)

#### Excluded Combination of Modules

- None

#### Aims

- This module is an introduction to String Theory, including supersymmetry and Superstring Theory.
- To introduce superstring theory through its two-dimensional worldsheet conformal field theory.
- To quantise string theory and show that the superstring spectrum includes all elementary particles thus unifying the fundamental forces including gravity.

#### Content

- Classical String Theory.
- Quantisation of String worldsheet theory.
- String theory spectrum and spacetime interpretation.
- T-duality and D-branes.
- Supersymmetry.
- Superstring theory.

#### Learning Outcomes

Subject-specific Knowledge:

- Having studied the module students will know the basic principles of worldsheet (super)string theory.
- The relation between the (super)string worldsheet theory and spacetime fields which are de-scribed using quantum field theory in the corequisite modules.
- The concept of duality whereby apparently different theories are equivalent, with T-duality as an example.

Subject-specific Skills:

- Students will be able to apply a variety of advanced techniques in the area of string theory.
- Students will be able to how symmetries and constraints of the worldsheet theory lead, af-ter quantisation, to a specific spectrum with a spacetime interpretation.

Key Skills:

- The students will have developed the ability to operate in complex and specialised contexts close to the cutting edge of current research.

#### Modes of Teaching, Learning and Assessment and how these contribute to the learning outcomes of the module

- Lectures demonstrate what is required to be learned and the application of the theory to practical examples.
- Subject material assigned for independent study develops the ability to acquire knowledge and understanding without dependence on lectures.
- Assignments for self-study develop problem-solving skills and enable students to test and develop their knowledge and understanding.
- Formatively assessed assignments provide practice in the application of logic and high level of rigour as well as feedback for the students and the lecturer on students' progress.
- The end-of-year examination assesses the knowledge acquired and the ability to solve predictable and unpredictable problems.
