KAC Memorial Lecture: The phase diagrams of the high temperature superconductors

Subir Sachdev
Harvard University

The last three decades have witnessed the discovery of many new superconductors, with properties dramatically different from the conventional low temperature superconductors described by the Bardeen-Cooper-Schrieffer theory. These new superconductors can have much higher critical temperature, and all display antiferromagnetism in their phase diagrams. I will highlight important experimental discoveries of the past two years, and argue that they support a unifying theory and phase diagram for these new superconductors. The quantum critical point describing the loss of antiferromagnetism in a metal plays a central role in this theory.
