Abstract:

After 18 years of work, we still do not have a reliable theory for the high-temperature superconductors; even the mechanism that is responsible for the pairing of electrons that leads to superconductivity is disputed. One reason for this is the anomalous nature of the normal state, and in this talk I will review the physical properties of the so-called pseudo-gap phase, which corresponds to the under-doped normal state. In particular, I will present our recent work showing how such behaviour is not limited to low-dimensional systems.
