Abstract

The arguments presented in PRL. vol. 102, 056404 (2009) are discussed in the context of the vast literature on spectral weight transfer in doped Mott insulators. We show that the conclusions regarding spectral weight transfer in PRL. vol. 102, 056404 (2009) are, where novel, internally inconsistent and where correct, have been reached at least 18 years ago.
