SUMMARY:The Phase Diagrams of the High Temperature Superconductors\, P
 hysics Department Colloquium\, Subir Sachdev\, Harvard
DESCRIPTION:The last three decades have witnessed the discovery of man
 y new superconductors\, with properties dramatically different from th
 e conventional low temperature superconductors described by the Bardee
 n-Cooper-Schrieffer theory. These new superconductors can have much hi
 gher critical temperature\, and all display antiferromagnetism in thei
 r 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 &quot\;strange metal&quot\; region of the phase diagr
 am\, and its recent holographic description by methods drawn from stri
 ng theory.
