Abstract
This talk will summarise some of the key elements in the phenomenology and physics of high-temperature superconductors (HTS). HTS are characterised by a rich phase behaviour as a function of doping with several singular points associated with a metal/insulator transition, a van Hove singularity and possibly several quantum critical points. Characteristic length scales are very short while several relevant energy scales are comparable in magnitude and large. This makes for an exceedingly complex milieu in which superconductivity arises. Is this complexity essential to the phenomenon of remarkably high-temperature superconductivity? Contrary to expectation it will be shown that many aspects of the essential physics of these materials are surprisingly conventional.
Series This talk is part of the Quantum Matter Seminar series.
