摘要: A fundamental theoretical characterization of a many-body system such as that defined by the Hubbard Hamiltonian is single particle Green’s function G. Single electron spectroscopies provide means to measure spectral weight G and so these are in principle very powerful experimental testing predictions for model. This article gives an overview problems opportunities associated with application spectroscopy this problem.
