Nonequilibrium-DMFT based RIXS investigation of the two-orbital Hubbard model

Resonant inelastic X-ray scattering (RIXS) detects various types of high- and low-energy elementary excitations in correlated solids, this tool will play an increasingly important role investigations time-dependent phenomena photo-excited systems. While theoretical frameworks for the computation equilibrium RIXS spectra are well established, development appropriate methods nonequilibrium simulations active research field. Here, we apply a recently developed dynamical mean field theory (DMFT) based approach to compute response two-orbital Mott insulators. The results demonstrate feasibility multi-orbital calculations sensitivity quasi-elastic fluorescence-like features d-d excitation peaks on population Hubbard bands.
