Localized and itinerant character of electron states in the photoemission from CuGeO 3

It is shown that electron correlation among Cu d-electrons explains the photoemission data of CuGeO 3 and is responsible for the insulating behaviour and of the observed complex satellite structures. The analysis and interpretation of the experiments require the use of a multi-band Hamiltonian which...

Summary:It is shown that electron correlation among Cu d-electrons explains the photoemission data of CuGeO 3 and is responsible for the insulating behaviour and of the observed complex satellite structures. The analysis and interpretation of the experiments require the use of a multi-band Hamiltonian which explicitly includes both on site electron correlation and a detailed description of the single-particle band states.
