Optional for all degree programmes within Physics and Astronomy. Particles and Nuclei/A Quantum Approach to Solids (03 26017) and Condensed Matter Physics (03 01123) are advised pre-requisites, although Condensed Matter Physics (03 01123) may be taken concurrently.
The course aims to introduce Y4 students to a broad range of advanced subjects in Condensed Matter Physics. In the first part of the course, the students will learn in depth about theoretical and experimental approaches used to investigate the optical properties of the condensed matter. The students will be taught about optical response of semiconducting and superconducting materials in the bulk form and when their dimensionality is reduced to 2D and 1D. In the second part of the course, the students will learn about Quantum Hall observed in 2D electronic systems at low temperature and its fundamental importance in quantum electrodynamics. The course also provides background for understanding of the surface states which will be preceded by the presentation of Anderson localisation model. Finally, the course provides an introduction to the new topic of topology in condensed matter. Overall, the course will be kept simple and useful for students with very different backgrounds and motivation.
