Failure of t-J models in describing doping evolution of spectral weight in x-ray scattering, optical and photoemission spectra of the cuprates
t-J models x-ray scattering optical and photoemission spectra cuprates
2010/11/19
We have analyzed experimental evidence for an anomalous transfer of spectral weight from high
to low energy scales in both electron and hole doped cuprates as a function of doping. X-ray
scattering,...
