On thursday I am giving a Physics Colloquium in the Faculty of the University, "Bad metals, good superconductors, and quantum spin liquids."
Here is the current version of my slides. I am concerned the talk is not at a basic enough level for the general audience. I highlight four key concepts stimulated by the discovery of cuprate superconductivity:
- Mott insulator
- Superconductivity resulting from purely repulsive electronic interactions
- Quantum spin liquids
- Bad metals
These all find a nice realisation in organic charge transfer salts.
