A new framework is developed to evaluate the time-dependent RIXS signal using nonequilibrium dynamical mean-field theory simulations, which can be applied to study time-resolved RIXS processes in multiorbital systems. This approach avoids the need to compute complex four-point correlation functions.
We develop a framework to evaluate the time-dependent resonant inelastic x-ray scattering (RIXS) signal with the use of nonequilibrium dynamical mean-field theory simulations. The approach is based on the solution of a time-dependent impurity model which explicitly incorporates the probe pulse. It avoids the need to compute four-point correlation functions and can in principle be combined with different impurity solvers. This opens a path to study time-resolved RIXS processes in multiorbital systems. The approach is exemplified with a study of the RIXS signal of a melting Mott antiferromagnet.
