Doping evolution of the charge excitations and electron correlations in electron-doped superconducting La${}_{2-x}$Ce${}_x$CuO${}_4$

J. Q. Lin, Jie Yuan, Kui Jin +10

Electron correlations play a dominant role in the charge dynamics of the cuprates. We use resonant inelastic x-ray scattering (RIXS) to track the doping dependence of the collectiv…
