Abstract

Several experiments by different authors have established the existence of an 'anomalous' photoemission effect in one-dimensional systems, including one-dimensional metallic crystals and other examples of one-dimensional metals. The effect consists of the suppression of the photoemission signal at energies close to the Fermi level -- whereas for metals one would expect to see a Fermi edge. Increasing evidence exists, in our opinion, that this phenomenon is due to the decoupling of charge and spin coordinates and to a departure from the Fermi-liquid framework. If confirmed, this conclusion would be extremely relevant to high-temperature superconductivity, since it would pave the way to the use of a similar concept for non-Fermi- liquid theories of high-temperature superconductors.
