- The Phase Diagrams of the High Temperature Superconductors
- Time: 4:00 pm
- Place: 2241 Chamberlin Hall (coffee at 3:30 pm)
- Speaker: Subir Sachdev, Harvard
- Abstract: 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. I will also note the still mysterious "strange metal" region of the phase diagram, and its recent holographic description by methods drawn from string theory.
