Numerical studies of inelastic light scattering in correlated materials
Abstract/Contents
- Abstract
- The mechanism of high temperature superconductivity has been a puzzle for almost three decades. With the rapid development of synchrotron light sources, photon spectroscopies such as x-ray absorption (XAS), inelastic x-ray scattering (IXS) and resonant inelastic x-ray scattering (RIXS), have shown to provide more and more useful information for the study of elementary excitations in strongly correlated ma- terials. In particular, RIXS at the Cu K-edge has been shown to be a probe of charge excitations. RIXS at the Cu L-edge in hole-doped cuprates has been shown to measure high energy collective spin excitations which persist well into the overdoped regime. We perform numerical simulations to study light scattering cross-sections using the single and multi-orbital Hubbard models. Our calculations highlight the ability to obtain spin and charge dynamical structure factors using Cu L or K-edge RIXS, respectively, and the importance of incident energy dependence (or the res- onant pro le) and the full in uence of light polarization. Our results ll in the gap between theoretical understanding and inelastic light scattering experiments on correlated materials, and further provides useful information for understanding the superconducting mechanism.
