Joint HET/RIKEN/YITP Seminar

"Quantum Criticality and the Cuprate Superconductors"

Presented by Subir Sachdev, Harvard University

Wednesday, April 28, 2010, 2:00 pm — Large Seminar Room, Bldg. 510

I will begin with a simple introduction to the theory of quantum criticality, as applied to experiments on certain insulating antiferromagnets. I will then survey the phenomenology of the cuprate high temperature superconductors, and show how ideas from quantum criticality have helped explain or predict the results of a number of recent experiments. The applications to the cuprates focus attention on key problems associated with the criticality of Fermi surfaces in two dimensions which remain unresolved. I will describe how these open problems are being addressed by the AdS/CFT correspondence discovered in string theory.
