Learning Outcomes

On successful completion of this module students should be able to:

1. Identify and classify phase transitions in a variety of physical contexts.
2. Demonstrate familiarity with the physics and materials science of Soft Matter systems (e.g. polymers).
3. Summarise the key underlying physics of Superconductivity; to include the Meissner effect, type I and II superconductivity, and macroscopic quantum coherence according to Bardeen-Cooper-Schrieffer (BCS) theory.
4. Demonstrate familiarity with the concepts of the Landau theory of phase transitions.
5. Identify appropriate order parameters to describe phase transitions and suggest experimental techniques to track phase transitions.
6. Describe and explain the distinctive properties of nanoscale materials and nanoparticles.

Brief description

This module builds on the fundamental condensed matter physics developed in PH32410 and exposes students to some advanced topics and current research. Topics include soft matter, superfluidity, superconductivity, nanomaterials and phase transitions. Technological applications of functional materials such as organic electronics, thin-film photovoltaics, switchable devices and superconducting magnets are introduced alongside the physics supporting them.
