Energy Scale of the Self-Energy in High-TC Superconductors
arXiv:cond-mat/0405400
Abstract
The contradictions between some recent statements about the origin and the doping dependence of a sharp peak in the electron self-energy obtained from optics and ARPES are discussed. It is shown that the conclusion of Hwang et al. about disappearance of a mass renormalization in the highly overdoped regime is unfounded.
