<p>This unit aims to provide an overview of advanced topics in Condensed Matter Physics, in particular superconductivity, low-dimensional quantum systems, and nanoscale physics. The unit develops the basic frameworks required to understand topological phases of matter and other emergent phenomena in Condensed Matter systems and at the nanoscale/atomic-scale and related modern techniques to probe such phenomena and physical properties. The unit also presents experimental developments in the field that have occurred in the last few years, giving students a flavour of modern research work in academia or industry. </p>
