Where is the quantum critical point in the curprate superconductors?

The existence of one (or more) quantum critical point has been one of the central issue in the puzzle of the cuprate superconductors. In this article, Subir Sachdev, a world-renowned expert in this area, discusses where such quantum criticality might exist in the cuprate phase diagram based on electrical transport measurements.
