| Abstract: | A basic overview will be given on the various experimental observations in the pseudogap regime of the cuprate superconductors. Even after 24 years, the pseudogap phase is not yet fully understood, and there are two very different views on the origin of this phase. In one view, the pseudogap phase is modeled as a precursor to superconductivity. This model presumes the existence of uncorrelated pre-formed pairs of electrons above the superconducting transition temperature Tc, which become phase correlated (and therefore superconducting) at Tc. In the other view, the pseudogap phase is either a competing order to superconductivity or a phenomenon which has nothing to do with superconductivity. All these will be presented and discussed briefly in view of the experimental data, and at the end, Tal’s contribution to this field will be explained and highlighted. |
