Mott physics revealed in high temperature superconductors by resonant inelastic X-ray scattering experiments
ORAL
Abstract
In recent resonant inelastic X-ray scattering (RIXS) experiments, energy dispersions of measured spin-wave or paramagnon excitations of cuprates show no signs of softening up to 40\% hole doping or substantially hardening after only 15\% electron doping. In this talk the anomalous result is explained by a simple explanation based one the t-J model. It reveals the presence of the strong correlation of Mott physics in highly doped cuprates. Some predictions will be also presented.
