Abstract

We argue that the photoelectric effect in high-temperature superconductors is not only a source of external valuable information, but one of the most important and interesting open problems in today's physics. Even without a complete picture of this phenomenon, very important conclusions can be obtained from an empirical analysis of photoemission data, notably on the parity and on the link between superconductivity and Anderson localization. But a complete theoretical framework is urgently needed. Its development can contribute to the conceptual revolution that might be necessary to understand high-temperature superconductivity, as the Drude-Fermi-Landau revolution was necessary to understand metallic conductivity.
