| Abstract | As an increasingly important probe of charge dynamics for systems of strong correlation, resonant inelastic X-ray scattering (RIXS) has the ability to highlight various many-body excitations that can be characterized in terms of photon momentum transfer as well as energy loss. Here we perform exact diagonalization method with multi-orbital Hubbard hamiltonian, to uncover the nature of the excitations seen in recent RIXS experiments on the parent compounds of cuprate high temperature superconductors: La2CuO4 (LCO), Nd2CuO4 (NCO), and Sr2CuO2Cl2 (SCOC). By comparing and contrasting our simulation results with experiment, we can study the influence of different orbitals on the RIXS spectrum, and also determine the orbital character of the excitations in different regions of the Brillouin zone. |
