Fig. 3: Momentum distribution for time-resolved Resonant Inelastic X-ray Scattering (trRIXS) spectra.
From: Witnessing light-driven entanglement using time-resolved resonant inelastic X-ray scattering

From left to right: trRIXS spectra for the 1D momentum q ranging from 0 to π, at \(t=-5{t}_{{{{{{{{\rm{h}}}}}}}}}^{-1}\), t = 0, and \(t=5{t}_{{{{{{{{\rm{h}}}}}}}}}^{-1}\), respectively. The incident energy ωi is set as 1.8th and the upper insets show the time relative to the pump pulse, whose condition is the same as Fig. 2.
