Momentum Dependence of Resonant Inelastic X-Ray Scattering Spectrum in Insulating Cuprates
Momentum Dependence of Resonant Inelastic X-Ray Scattering Spectrum in Insulating Cuprates
The resonant inelastic x-ray scattering spectrum in insulating cuprates is examined by using the exact diagonalization technique on small clusters in the two-dimensional Hubbard model with second and third neighbor hopping terms. When the incident photon energy is tuned near the Cu $K$ absorption edges, we find that the features …
