All of this makes quantum fluctuationsvery important. Their phase diagram is thus a challenge for the usual tools ofsolid state physics. I will show how aperspective that takes into account both the localized and delocalized aspectsof conduction electrons can explain, at least qualitatively, most experiments.More specifically, I will show that the work of several groups using clusterextensions of dynamical mean-field theory sheds light on phenomenacharacteristic of this class of systems: the pseudogap, the quantum-critical phenomenaand d-wave superconductivity. In another talk,Part II, I will argue that we know what leads to the largest transitiontemperature.
